I just want to say that you guys have one of the best if not the best customer service in the industry. Between Chester and Mark working with me on my transmission noises to my original order, the twin disc clutch and Tremec TKO-600 trans are doing great now. I didn't believe youguys when you told me to set the rear pinion angle down to match the motor, it goes against everything you read about driveline angles. It sounded like parts were scraping together in the transmission and all of a sudden it stopped. No noises whatsoever anymore, and smooth as could be. Thanks guys, I really do appreciate it. You even started building me a new transmission to correct the problem I thought I had! I very much appreciate everything.

I took a T-350 trans out of this car for a customer and installed a Tru-Shift Throttle Correction System 700-R4 / 200-4R. I bought all kinds of brackets but could never get it to shift right. I saw an ad in Street Scene magazine for the Bowler kit. I just installed it and can't believe how much nicer this car is now. I am ordering another one for a 64 Chevelle with a 200-4R in it.

I purchased a complete Bowler Tru-Street 4L80E Performance Transmission & Converter package and couldn’t be happier. The transmission is silky smooth with the perfect shift hardness and the install came together flawlessly. Jeff was extremely knowledgeable and friendly and provided his invaluable guidance with choosing the right combination, shipping was earlier than promised, and the post-sale tech support from Mark and Jeff was top-notch and exceeded my expectations. This company truly cares about their products and needs of their customers. I highly recommend Bowler Transmissions.

I've driven probably 20 or 30 Bowler equipped cars. They all shift smoothly and are extremely reliable. My favorite was an upgraded TKO600. They are nice transmissions from the factory but suffer from terrible gear clash from 3-4. Once Mark and his team did their magic, it would shift 3-4 at nearly 7000 rpm with no trouble whatsoever. Good stuff.

I am a classic car shop in CT. I have installed several of these transmissions in cars and always had trouble with the TV cable adjustments. I did them with shift feel, but always skeptical of ruining a customer's transmissions. I saw an ad for this kit in Street Scene magazine and decided to try one. The first one was in a 38 Chevy coupe, street rod. It worked so good I just installed one in a 64 Chevelle with a 383 stroker engine. The results were the same, they both shifted like a normal car.
