“I have always been a three pedal guy, and I wanted to add an overdrive to my factory four speed El Camino. The Classic Motorsports Group, formerly Classic Chevy 5-Speed kit made replacing the old Muncie with a modern Tremec a bolt-in operation with some minor floor pan modifications and trimming. The installation notes section of the website was very helpful, and the Classic Chevy Tech line helped us be sure we would have all of the parts we would need before we started the job. I couldn’t be happier with the conversion, and all of the components we purchased from Classic Chevy 5-speed were top notch.”

As the owner of Street Shop, Inc. we exclusively use Classic Motorsports Group’s Ultimate Fit TKO for our custom Corvette applications. We have been creating chassis and drivelines for Corvette "Retro-rods" for 7 years and have used transmissions from other manufacturers, however the quality, service, range of supporting components and knowledgeable sales staff at Classic Motorsports Group easily won over our business.

"I dealt with over 30 suppliers when I built the Silver Spur and Classic Motorsports Group was the absolute best in customer service. Jeff and Scott always responded quickly and honestly with both technical help and quality products delivered. I was on a deadline to make the SEMA show in Vegas and their dedication to customer service was off the chart! Every time I called they took care of my need immediately including confirming the product ordered along with the tracking information for shipment. Their transmission kit bolted in without a hitch and continues to work perfectly going through the gears. I am in the process of restoring a 1970 Chevelle and their transmission kit will be going in it also."

When Corvette Enthusiast contacted me and asked me to build the Carlisle Project “King Ray” Corvette for the 2006 Corvettes at Carlisle event, I happily agreed. I had a project plan in mind to build a 572 cubic inch powered 1967 Corvette with a Tremec TKO transmission.
I was specific: I wanted the Tremec to be supplied by Classic Motorsports Group.
From past experience I knew their product was of excellent quality but, more importantly, I knew their customer service and technical support was far superior to the competition.
Classic Motorsports Group is the only place to get your Tremec TKO for your Corvette.

I am very fortunate that I am able to build great cars as a profession. Recently, I had the opportunity to build two identical, 1969 Camaros each having the same drivetrain. I ordered the Classic Chevy 5-Speed Elite TKO kit for one car and I purchased the other “complete" TKO kit from a different company. Hands down, the Classic Motorsports Group kit was easier to install, it was more complete, and it include higher quality parts. I needed to utilize both companies tech lines – I called the “other” company about five times for various issues and I called the Classic Chevy 5-Speed line only one time and it was to say “thanks”. I will be using Classic Chevy for all of the future cars that I build where a manual transmission is required. Thanks Again.

Just thought I'd drop you a line to tell you how pleased I am with the gearbox which is now fitted and working perfectly. My mechanic who fitted the kit was very impressed with the fit and the quality of the whole package.Again thanks for the quick professonal service and I won't hesitate to recomend you and your company.
Kind regards

I just installed the TKO 600 in my 63 corvette and things all fit as advertised. Any questions I had were answered by your instructions such as floor sag and tunnel centering. A quality product that I would recommend to anybody that wants to drop their highway rpm’s and still have a good launch. Also, the TKO 600 can be installed by one person without removing the motor without a car lift and no transmission jack.

I just purchased the Tremec from Jim at Classic Chevy 5 Speed and can't say enough about his support. We probably phoned and emailed back and forth about 20 times (mostly my dumb questions), and Jim guided me along at every step. He even sent me photos that weren't on their website to further advise me on how to cut the hole for the shifter. The kit was everything I hoped it would be and I can't wait to get out and drive it.

I’m impressed. I got my ‘62 Corvette back from the installation shop and I couldn't be happier with it. After much research and many phone calls and emails I bought the Ultimate Fit Vette Kit from Classic Motorsports Group. I choose the Ultimate Fit Vette Kit with the specially modified TKO-600 transmission designed to fit the 1958-1962 Corvettes. It is a complete bolt-in kit. Other than removing the ashtray pocket so the larger Tremec could fit in the tunnel, there were no modifications required to the car and the shifter came up in the stock location. The McLeod designed shifter is second to none – it is the smoothest most positive shifter I've ever seen. With the 5th gear overdrive for low RPM highway cruising and the lower first gear ratio for great off-the-line performance, the TKO-600 has made my ‘62 a much more enjoyable car to drive. With this transmission I was able to drop my RPM's at 65 MPH from 3600 to 2300 and I actually gained more “pop” off the line with the lower first gear. In my opinion, Jeff & Scott at Classic Motorsports Group are the best. They were always available to answer my questions both before and after I made my purchase. I can't say enough about Classic Motorsports Group’s Ultimate Fit Vette kit and what it has done for my car.

Thanks again Classic Motorsports Group. After all of your advice about the swap and then taking the time to ask if I found the pilot bearing, comes as a pleasant surprise.  In the three years that I spent building my car and ordering parts, almost on a weekly basis, I have never come across a more helpful and customer oriented company as Classic Motorsports Group. I will definitely pass on my good experiences to those who inquire about my swap.

The second best money I ever spent is with Classic Motorsports Group (best spent money has been on my wife). The transmission is great and is smooth to operate. It dropped my rpm’s down by 1320 in 5 th gear so I can now cruise at 75 to 80 MPH effortlessly. I did the transmission swap in my basement garage by myself. The provided tunnel cutting template was perfect. Also, I love the slightly lower 1st gear my wife can drive the car with now as she can let the clutch out at idle and not kill the motor. The McLeod clutch and pressure plate package is great – smooth and soft on the leg muscle, but yet has great hookup for the occasional drag race. The custom driveshaft was perfect fit. I can’t say enough about your package and the customer service I have received from your company. Thanks so much.

For any of you out there considering a 5 speed swap for your car, allow me to share my own observations. There are several sources out there now where you can purchase a Tremec TKO transmission and the pricing is all fairly competitive. For me, as with any major purchase, it comes down to customer service. Classic Motorsports Group has been involved with research and installations of these products, and they are always willing to answer questions as they come up. They have engineered vehicle specific components that have made swaps as close to bolt in as is possible. They continue to be involved with research & development on new components, such as high performance shifters. They have always (including long before, and long after I purchased anything) been prompt with e-mail and phone responses to questions I have had. Most recently I had ordered a one piece speedometer cable from them, and it took a few days longer than any of us expected to arrive. Yesterday I had a message on my machine at home asking if I had received the cable, which I did that day. Personal touches like that go a long, long way. I am doing everything I can to get my friends who own muscle cars to install a Tremec - it is by far the best mod I have done to my car. The excellent customer service I received from Classic Motorsports Group just made the whole experience even better. Take all this for what it's worth, but for my money, there is no other vendor to consider for a Tremec swap.

I just recently purchased two TKO’s from Classic Motorsports Group (a 600 and a 500). They were informative and would answer any simple question I had. What a class act! Thanks.

It's the best money I have spent so far on my Chevelle. The guys at Classic Motorsports Group have been great! The McLeod shifter is the best offset shifter on the market today. I have no problem recommending the shifter and Classic Motorsports Group.

Once again, I cannot say enough good things about Jeff and Scott at Classic Motorsports Group. Unlike a lot of other companies, they listen to the customer and are committed to providing the best kits that they can. If they'd been up and running when I bought my TKO, everything would have come from them, instead of just the bits and pieces that they have figured out how to make better than the other guys.

I just wanted to say thanks for all of your help during this install. I really appreciate the fact that you always got back to me in a timely fashion and were very knowledgeable about this product.

I just got my TKO-600 from Classic Motorsports Group today. Thanks again, Jeff for all of your help - awesome service. I also can’t wait for the new offset shifter. I don’t know if you already purchased all of your adaptors, yokes, etc. yet but Classic Motorsports Group has some quality stuff. My integrated speedo cable fits like a glove.

I would highly recommend Classic Motorsports Group. I bought my TKO from a competitor, and I have received more help from Classic Chevy than from the company I bought my TKO. I haven't even been able to give Classic Chevy any business yet and they still help me out! They have been incredible. They are highly knowledgeable.
Tom

 Classic Motorsports Group was helpful at every step along the way, and went so far as to call me at home one night to give me the really good news that the TKO-600's had arrived much sooner than he had anticipated, and mine would go out the next day. If anyone out there is considering a TKO purchase, I can only say look no further than Classic Chevy 5 Speed.
John

The guys at Classic Motorsports Group were fantastic in helping me pick out the correct TKO conversion kit for my 65 SS Chevelle. Everything was as described and the install was a breeze. If you are considering installing a 5-speed in your muscle car, Jeff and Scott can help make the whole process painless. These guys have covered all of the bases for you.

Classic Motorsports Group is unbelievable! I have been working on a conversion on my 67 GTO and I purchased their TKO 600 kit. They have been so helpful and so punctual with call backs and delivery that I am basically blown away. I am in Kentucky and they are in California, and it is like they are right down the road. I talked to all the major dealers when I was looking at doing the conversion, and these guys are fully head and shoulders above the rest. I am just so happy to have found that there really are people left in the world that will do exactly what they say they will do, when they say they are going to do it.

Just wanted to let you know that my conversion from a Turbo-Hydro 350 to the TKO-600 in my 1971 Camaro Z28, using your Elite Kit, has been an extremely satisfying experience. The kit's completeness was perfect and the instructions/guide facilitated our being able to perform the conversion in one 10-hour day. I have put lots of miles on the vehicle and the performance and feel of the clutch and shifting just gets better and better. Thanks again for engineering a great conversion package. I now can enjoy comfortable and "easy on the gas" trips with a 3.42 rear end at 70 mph.

I just installed my TKO-600 kit from Classic Motorsports Group and I am very happy. The customer service was excellent. I was on the phone with Jeff, Jim and Scott several times with questions during my installation and they were all very helpful. I highly recommend them.

A few years ago, I built my replica AC COBRA powered by a 305ci Chevy but I was never very happy with my old T10 gearbox. This year I decided to swap the T10 and I found Classic Motorsports Group, formerly Classic Chevy 5-Speed on internet. I am probably the first French client of this very friendly company and I was very excited to deal with the Classic Motorsports Group team. As soon as we agreed on the terms of payment (probably unusual as an overseas client), the transaction was handled very quickly. From the day I finalized my order it only took 10 days for my new TKO to cross the ocean and arrive in Geneva. I ran into a few issues with my clutch set up but Scott from Classic Motorsports Group was always very friendly and helpful. I called several times with technical questions and the replies were always very quick and precise.

When funds permit, I will build a COBRA 289 FIA and I will definitely contact Classic Motorsports Group for another TKO transmission. I appreciate your service and prices.

Just a quick note to anyone considering the Tremec 5 speed setup. You won't find a better bunch of guys at Classic Chevy 5 Speed to work with. Almost without exception you'll probably have some issues with the install. Just today I had an install question....Jeff called me back in 15 minutes! You want answers and quick response.....Jeff and his group will not disappoint. They are car guys just like us. Look beyond price........you'll soon forget about what you paid for your setup when you start looking for answers.

“I am a professional mechanic that has been in the automotive field for over 30 years. My Classic Motorsports Group Tremec TKO 600 transmission conversion kit was complete and included very accurate installation instructions. It was one of the easiest drivetrain modifications I have ever done. I can also say that, I HAVE NEVER HAD THIS MUCH FUN DRIVING THIS CORVETTE BEFORE. The instructions are precise, the customer service is instant, and the follow up contact from the guys at Classic Motorsports Group is unequalled.”

I purchased my 5 speed about two months ago and I can tell you that I have never owned a vehicle that shifts as smooth as this one does. It is effortless, quiet, and very responsive. I show my 66GTO and sometimes I drive her up to Tahoe. Prior to installing my 5 speed I used to travel up there doing no more than 60 – 65 mph because my 4 speed was roaring at 3000 rpm. Now I can go up there in comfort and confidence and doing 2000rpm @ 70 mph God I love this transmission! Thanks for supplying a great product and helping with some of the questions we had.

The CC5S C4 TKO kit is superbly designed and engineered.  This transmission shifts excellent and can handle anything I throw at it.  Gone are worries about breaking my 4+3.  The TKO has increased my enjoyment of the car exponentially.  Previously, this car was driven once every week or two.  Now, I drive the car every day of the week!  I think up of reasons to drive.  First to second shifts are perfect and I can hit it hard.  The car just digs in and the drivetrain is solid.  The true test of a shifter design is the delicate second to third shift, and this shifter ALWAYS goes into third.  This trans is highly recommended and worth every penny and more.  It will change the whole character of your car.  The CC5S crew is extremely knowledgeable and are true enthusiasts who love their trade.  Thanks guys!
