You just have to read the entire article and then seem my comments.
I make no judgement (like some of the other commenters) on whether Aaron is a “real car guy”, in fact I’m sure he is a ‘car guy’ – just one of ‘THOSE’ car guys. (If you are a real car guy you’ll know what I mean).

I’m going to take a lot of heat for what I’m about to say. While no manufacturer can expressly admit it, behind closed doors, deep within the bunkers in Detroit, Munich, Stuttgart, and Tokyo, most engineers will nod in agreement. With enough soul searching, quite a few of my fellow automotive writers will find themselves agreeing, too. The visceral allure of the manual transmission as we know and love it isn’t….
I’m a bit old school about driving like feeling the road (yeah even the pot holes!!) and not floating, making a car hit the curve just right and shoving the clutch pedal to the floor and find the next gear! That’s all part of the enjoyment for me. But paddle shifting is here to stay and I’ll be disappointed if the clutch pedal disappears from all new cars.
I’m sharing this article from Mind Over Motor as it hits on some key points I can relate too when it comes to this “new fangled” 🙂 way of changing gears.
Mind Over Motor
I am someone who has publicly lamented the decline of the manual transmission. But I’m also someone who has enjoyed the merits of modern paddle shift gearboxes in many cars.
I find myself very much split on this issue, so lets take a look at the various reasons why shifter paddles are replacing a gear lever and a third pedal in some of our favorite cars.
Note: To clear this up right away, by “paddle shift” I mean cars with automated manual gearboxes, either dual-clutch or single-clutch. I am in no way talking about anything like a Toyota Camry with the “sport package”, which has paddle shifters as a marketing gimmick.
1. More versatile on the road. (Having your cake and eating it too)
If you had something like a Lamborghini Diablo back in the mid 1990s chances are you had a lot of fun out on the open road. However, when you got into town and hit traffic, the heavy clutch made driving the car more of a $250,000 chore than an enjoyable way to spend a weekend afternoon. Considering the average speed of traffic on most roads is around 25-30mph, you’d be spending far more time putting along slowly than stretching the car’s legs. It’s a wonder why most owners hardly ever drove their exotic cars.
Today, Lamborghini only offers their cars with a paddle shift transmission. The sales numbers spoke for themselves, once paddle shift was offered back around 2004, demand for manual Lambos simply fell off.
Paddle shift basically solved all the issues described above with the Diablo. Now, in an Aventador, you can rip your way into town and then just put the car in automatic mode when you hit traffic. You have a car that is a ferocious supercar when you want one, but is also just as easy to drive as a Toyota Camry when you don’t. You are no longer writing a six-figure check to put yourself through misery. And I agree, that is a major plus, especially in cars that had very difficult manual gearboxes like most supercars did.

For most of us, we like our Mustangs to be well-rounded. Many of us can only afford one, so it needs to be able to do a few things other than just getting us from Point A to Point B. Fortunately, we can make a Mustang be good at a couple different types of performance without making wholesale changes. It’s pretty hard to make it great at several things at the same time, but we’re willing to make concessions in order to make it more than a one trick pony. We can take it to the drag strip, that’s easy. We can also take it road racing – which isn’t as easy – but we can still have a blast provided we have outfitted it accordingly with the right brakes. We can even take it drifting.
SPEC Clutches is a company that knows after the act of drag racing, drifting is something that comes natural to a Mustang. SPEC’s David Norton has been involved with drifting since the sport’s beginnings, and knows V8 power mixed with a tail-happy suspension, getting a Mustang to drift isn’t difficult.

With manual transmissions in demand, it isn’t surprising to find that a fair number of vehicles—particularly muscle-era vehicles—that left the factory with an automatic transmission are being rebuilt with a manual. Frederick estimated that about 60 percent of American Powertrain’s classic muscle car customers are replacing an automatic transmission with a manual.
“[The conversion] is time-consuming, but not terribly complicated,” Frederick said. “Most of the parts bolt in.”
“It isn’t for the faint-of-heart or for anyone short on patience, but it’s do-able,” Hill added. “It’s just a matter of working through the process.”
Obviously you’ll need a pedal assembly; fortunately, according to Hill, there are a lot of aftermarket units that work quite well.
“That also gives you the option of using a hydraulic release bearing instead of a mechanical clutch linkage, which, depending on the application, can have some advantages,” Hill said. “It’s going to take a longer or shorter drive shaft. It’s going to take a different yoke on that driveshaft. The power bushing in the motor for the transmission input shaft may have to be changed. The starter could be affected by the diameter of the flywheel you put into the vehicle.
“You start at the back of the crankshaft and start matching componentry as well as possible—and if you can’t match it, then you have to compensate for it,” Hill continued. “I don’t think we’ve ever run into something we couldn’t convert, as long as we’re talking about American muscle.”
Many of the same issues crop up even when swapping one manual for another—for example, the customer who has a 454 and a Muncie and wants to put a modern six-speed in it.
Like many other projects, it’s significantly easier with older (i.e., pre-computer) hardware. If either the engine or the transmission came with computer controls, it gets a little more involved. And keep in mind that even some modern manuals now have computer controls—the GM transmission that comes with the LS engine, for example, with its skip-shift function.
Of course, some customers will want to go the other way and replace a factory manual with a new, high-tech automatic.
“It’s most important to make sure you have all the correct components—and that you make the finished job look appealing to the customer,” said Poff of TCI. “It’s the mounting that’s most likely to give you trouble.”
According to the experts, you’ll need to ensure that you have the right crossmembers and that there’s enough room inside the tunnel.
“There is no one-size-fits-all solution; every application is unique,” added Poff. “But once the physical installation is accomplished, it’s pretty straightforward to make everything operational.”
Either way, Nichols suggested finding out from the customer how critical it is to keep the car looking original, versus the cost to locate and install all of the correct original components.
As with so much else in hot rodding, the best results generally come from purchasing and installing complete systems.
“That goes for any product from any company in this business,” Frederick said. “We say, ‘Look, we have a turnkey kit. We figured it all out, and all you to do it plug and play.’ Buy it all from one source and you know all the parts are going to work together.”
Meanwhile, manual-shift enthusiasts are upgrading to modern units packing more heavy-duty horsepower capacity—and more gear ratios.
“The generation that is now in their 60s can afford to build the cars that they wanted to build when they were in high school,” said Dick Hill, sales manager for Centerforce Clutches in Prescott, Arizona. And while those folks are not usually looking to build a race car, “they do want a four- or five-speed manual transmission,” he said.
More surprisingly, the trend extends beyond muscle cars and into traditional hot rods as well.
“I have friends who are building Deuce roadsters and they are putting LS motors in them, with a five- or six-speed manual transmission,” Hill said. “There are people who put Cadillac V-8s in 1949–1951 Mercs, and they want a stick. They want a three-pedal car. So that, too, is contributing to the growth of the high-performance clutch market.”
Hot rodders who already own or have owned multiple cars are now looking for something different.
“It’s like the people who buy their first Harley, they want it with every doo-dad they can get, where older bikers are turning back to the Knucklehead or even Flathead motors,” Hill said. “It’s the same with the hot rodder who already has two or three or four toys in the garage. The newest toy is going to be a stick car. And it’s for the same reason that someone will buy a brand-new Camaro, put 1,000 horsepower in it, and drive it on the street while blowing cold air and playing tunes. They want a manual not because they’re going to race it, but because they can have it. That’s what we hear all the time: ‘Because I can.’”
Rating the Ratios
American Powertrain of Cookeville, Tennessee, sells a broad range of high-performance drivetrain components, from complete crate engines to driveshafts and pedals. The company also distributes Tremec transmissions.
“The hot market right now is for the Magnum six-speed in a classic muscle car,” said Gray Frederick. “The Magnum is Tremec’s replacement for the T-56 is the aftermarket version of what you would get in a new Shelby GT500 or Camaro SS.” Frederick added that people are putting them into classic Mustangs Cougars, Camaros Firebirds, Barracudas and Challengers.
“The cars that people spend the most money on are the cars that [are] getting Magnum six-speeds,” Frederick added.
The Magnum is available with two sets of ratios, with the closer-ratio unit being the more popular of the two.
“The wide-ratio box has a 0.5 overdrive, which is very tall; a lot of engines can’t pull that much overdrive,” Frederick said.
But when it comes to overdrive, isn’t more better?
“That’s a myth,” Frederick said. “You can say, ‘Alright, I’m at the ragged edge of my cam, where if I’m on flat ground I can hold 70 mph all day.’ In a perfect world, that would be great. [I]n the real world, at some point you’re going to have to slow down for construction, and then speed up again; or you’re going to hit a rise, or something else that causes your engine to run out of breath. [T]hen you’re going to have to shift and that’s what you’re trying to avoid.
“You want to put it in sixth gear and leave it sixth gear,” he continued. “You don’t want to run down the highway at your cam’s peak performance, which would be 3,000–4,000 rpm. But you do want an rpm where your engine can pull your car up hills, and pass without dropping a gear. If every time you put your foot in the gas the engine lugs and you have to shift, that becomes very inefficient. We’re helping the customer understand that, even on the highway, you want to stay in your powerband. Otherwise the overdrive doesn’t do you any good.”
Frederick recommends the wide-ratio unit mostly for torquey big blocks.
“A Pontiac 455 will pull a stump out of the ground at 800 rpm; it doesn’t have trouble pulling a car at whatever rpm you’re running,” he said. “A Mopar 440 and some other big blocks with a lot of low-end grunt can usually handle the taller overdrive, too. And of course we’re dealing with a lot of electronically fuel-injected (EFI) engines now, and most of them have computers that can cope with low rpm very well.
They can retard the spark, they can meter the fuel differently, they can do all kinds of things.
“We help the customer choose a rearend ratio and a gear set that’s going to give them the best performance, from top to bottom,” Frederick said.
Pedal Pressure Another concern, according to Hill of Centerforce Clutches, is the physical effort once associated with a high-performance clutch.
“Our customers all ask, ‘How stiff is the pedal?’” he said. “That’s why we’ve been very successful, whether it’s a single-disc clutch for mild upgrade vehicle, or dual-disc unit that can hold 1,300 lbs./ft. of torque, we’ve been very successful in making them streetable.”
The average consumer, Hill said, could climb into a car with a Centerforce dual-disc clutch, push the pedal to the floor, and not realize that the car was modified.
“[T]he person who has a $75,000 Camaro or Corvette wants race-car performance without the race-car effort, so this is pretty significant,” he said.
Still, selecting the optimal clutch for any particular application is a complex task best left to experts.
“There are different linings and different friction materials on the pressure plate,” Hill said. “Heat is a factor. The first thing you have to know is how the vehicle is going to be used. Drag racers realize they are going to drive their car until they break it, where hot rodders don’t beat their cars up as bad. They are very proud of their cars and they want to drive them, not break them. And unless the car has been tubbed, a street machine generally runs smaller tires, so you want to tune the clutch for that.”
McLeod Racing of Placentia, California, offers its RST and RXT Street Twin clutches, both double-disc units that hold up to 1,000 horsepower, with the pedal pressure of a stock clutch, said President Paul Lee. Contributing to this low effort—and to easier installation—are McLeod’s hydraulic release bearings, “which fit most applications, replacing worn and/or outdated mechanical linkages,” he said.
“We’re selling more clutches for vehicles from the 1960s and 1970s, and installing a new hydraulic clutch in one of these cars can significantly reduce pedal effort,” said Rich Barsamian, national sales manager for Advanced Clutch Technology (ACT) in Lancaster, California. The company also offers a wide range of clutches for GM, Ford and Mopar applications, each rated for torque at the crankshaft.
When installing an aftermarket clutch, Barsamian suggested, “be sure to use the right amount of lube on the input shaft—it is possible to use too much. Be sure parts are free from dirt and oil, and washed in a non-petroleum-based cleaner such as acetone, alcohol or brake cleaner. Be sure to follow the correct torque and tightening sequence when installing the clutch cover—and do not use impact tools.”
This is a great article. If you are building a hot rod from scratch or you are taking your muscle car to a modern level you will find some good information in this piece. I toyed with the idea of putting a modern manual 5 speed trans in my 70 Mustang, but I opted for a rebuild Shelby 4 speed manual. (Check out all 3 parts.)
Derided as “slushboxes” in the days when hot rodding was young, automatic transmissions have long since closed the performance gap and won the respect of (at least some of) the most dedicated lead foots. Today, even the fuel-economy advantages of the old-standard stick shift are more memory than reality, as the shiftless set has drawn even with, or pulled slightly ahead of, the shifters. Backing up these advances is a great deal of detailed engineering, especially of the electronic variety.
But a lot of it’s simply due to more gears—a wider range of ratios, allowing for relaxed, low-rpm cruising with peak torque still available on demand. About 10 years ago, a four-speed automatic with a lockup converter was the hot ticket to optimize performance with economy. Now the OEMs are building five-, six- and seven-speed automatics—and hot rodders want them, too.
Not that the shift-for-yourself crowd has been caught napping—six gears are now the required minimum in any respectable OEM performance car, and that’s left three-pedal rodders craving more ratios, too.
More Is Better
“Enthusiasts in every segment of the hot rod and muscle car markets are removing traditional three-speed gearboxes and replacing them with modern four-, five- and six-speed transmissions,” said Stanley Poff, who heads product and sales for TCI Automotive in Ashland, Mississippi. “As they experience modern overdrive automatics in their daily drivers, they become more inclined to want the same driving experience in their hot rods.”
TCI’s new 6x Six-Speed can be adapted to most GM small-block, big-block or LS engines; Ford small and big blocks; and Chrysler small blocks, big blocks and late-model Hemis.
“We build it in a modified GM 4L80E case that’s been machined to accept modular bellhousings, and we keep all of the Reid Racing bellhousings in stock,” Poff said. “We can put together a complete package for all of those applications, including the transmission, bellhousing, EZ-TCU electronic control, cooler, shifter (conventional and/or paddle-type), TCI transmission fluid and a dipstick.”
TCI currently offers the 6x in two models, rated for 850 and 1,000 horsepower, respectively. Models for 1,250 and 1,500 horsepower are in the works, according to Poff.
The market has also responded well to the company’s EZ-TCU, he said.
“It allows you to retrofit a modern electronically controlled automatic transmission, such as our 6x, or the GM 4L60E, 4L65E, 4L70E, 4L80E or 4L85E, to a carbureted engine, or an engine with a self-tuning EFI system such as the FAST EZ-EFI,” Poff said.
TCI worked with FAST to develop the EZ-TCU.
“It follows the FAST model of being extremely user-friendly and easy to install even by people who lack either tuning or electronics experience,” Poff said. “We sell a lot of EZ-TCU units to people who want to put a crate engine and electronic transmission in a classic street rod or muscle car.”
Pete Nichols, sales manager for Hughes Performance in Phoenix, pointed to the classic muscle car market, where “more and more people are building these cars with significantly higher-than-stock levels of horsepower and torque,” he said. “That requires a premium, high-strength aftermarket torque converter and transmission assembly.”
To meet these demands, Hughes now builds all of its GM 700R-4, 200-4R and Ford AOD transmissions with the upgraded, constant-pressure valve bodies.
“These valve bodies contribute to improved shift quality and more consistent shift timing, while reducing the possibility of premature transmission failure due to a broken or incorrectly adjusted throttle-valve (TV) cable,” Nichols explained. “The new design also eliminates a lot of the complexity and hassle associated with the TV system on these transmissions, so retrofitting them into older cars is easier than before.”
Hughes has also introduced a custom bellhousing system that allows builders to bolt the popular GM 4L80E behind a wide variety of GM, Ford and Chrysler engines without using an adapter. The company offers custom 4L80E options for applications producing 500–1,500-plus flywheel horsepower, and for virtually any popular V-8 engine.
Nichols emphasized the need to properly flush the transmission cooler and cooler lines before installing a new torque converter.
“Debris gets easily trapped in the old cooler and then it gets flushed out during the initial run-in period, inevitably working its way into the valve body, governor, etc.,” he said, adding that getting a new cooler is the best way to prevent debris-related failures.

There will be hundreds of collector cars going up for auction at Barrett-Jackson this month, but few will be as interesting as this custom creation nicknamed the “Lockheed Lakester”. The car, registered for road use as a 1917 Crow Lakester Custom, was hand-built from the wing tip tank of a Lockheed Super Constellation and uses a mix of automotive and aircraft parts. Wedged inside the tank is a 1.8-liter turbocharged Hemi four-cylinder mated to a five-speed manual transmission, and the two-person cockpit features gunner seats and an air-speed indicator in lieu of a speedometer.
We’ll be bringing you live coverage of Barrett-Jackson later this month, so be sure to check back for more photos of the “Lockheed Lakester” and more in just a few weeks.
