Keisler's Builder's Series Kit is a great lower-cost alternative to the PerfectShift Kit for the car owner who is not concerned with an original look or using the factory console. The Builder's Series Kit includes all the same high quality components as the PerfectFit Kit, but with a non-customized transmission. Requires modification of the factory transmission tunnel and may not work with a bench seat. The shifter will come up in the center of the tunnel instead of offset towards the driver like the factory shift position.

Enjoy low-rpm cruising, great fuel economy, and less engine wear with the TKO-600 5-speed overdrive!

NOTE:  Pedals and clutch master cylinder not included at this time, please call for details.

Kelvin and Christy Cannon - '70 Nova

It was a 2 year decision and after looking at all options, I went with the Keisler TKO kit and I like it a lot!

Rich Bryant - '65 Nova SS

Just wanted to send a quick note and say thank you!
I purchased a TKO 600 Kit from you and installed it in my 65 Chevy Nova SS
I got the Kit with the offset Shifter I put the Hurst Shifter lever and the 4speed knob on it and with the 4speed console you can not tell it is has a 5 speed in it. People ask all the time is it a 4speed and I just smile and say No it a 5 speed and I got it from Keisler Engineering!!!!
Boy what a difference it made in the way the car Drives and Shifts, I have a 410 Gear in the rear and it dropped the RPM down to 2100 At 70 MPH from 3300 before at only 55 to 60 mph.
I would say the hardest part of putting it in was dialing in the bell housing.

Thank you for a Great Product!!!!!
