Who do you trust with an automatic transmission when you are building this kind of a machine with this kind of power plant.For Corvette conspiracy it is an easy question to answer We trust Zack Farah of Gear Star performance transmissions because we need our transmissions to function perfectly and reliably every time.

Thanks Zack!

Hello Zack, Thank you very much for the great job you did on my Marauder no more slipping between 1st and 2nd gear. it hits hard on the 2-3 shift and 1-2 is just insane I really like it the difference is unreal, the car has a Kenny Bell package on it and for the 1st time I feel we are really putting the power to the ground. I can cruise at 35MPH and punch it will just smoke the tires.


Zack, I just wanted to drop you a line to let you know that the transmission you built for my '06 Silverado is unbelievable it shifts perfectly and works real nice. thank you for the great service.


Attn Zack Farah, I would like to thank you for the service I received at your shop. I had a problem with my C-4 and Mark & Larry were very helpful in solving the problem in a timely manner. I like doing business with a company where service is not a 'BUZZ' word. I will highly recommend "Gearstar" to anyone who wants to deal with a reliable shop. PS. I ran 10:55 at 128 MPH with a 1.45 60 FT Time Fast enough for a 71 year young grandfather!

I want to thank Gearstar for sending a technician over to our shop a couple of weeks ago to assist in connecting the kickdown linkage on your 200R transmission. The technician was extremely helpful in getting this car on its feet. His professionalism, attitude, and knowledge made it all possible. We look forward to our continued growing relationship with Gearstar and certainly wish you guys the best moving forward.

Zack, I just wanted to drop you a line to let you know that the transmission you built for my '06 Silverado is unbelievable. It shifts well and works perfectly. Thank you for the great service!
