Keisler ClassicFit™ Shifter for Tremec TKO, 1964-1973 Mustang

Keisler ClassicFit" Offset Shifter is now available! It provides the same correct shift lever attachment point as our premium PerfectFit" series, but in a lower cost "bolt-on" package. Modification of the 4-speed shifter hole is required for some applications. (Note: If you desire minor or no modification, please see our PerfectFit" series of transmission systems.)

FAQ: What is the difference between Keisler ClassicFit" and Keisler PerfectFit"?

Keisler PerfectFit" is a version of the Tremec transmission that is heavily customized by Keisler. The aluminum main cases are machined to fit the larger Tremec transmission into the factory tunnel with minimal or no modification to the car. The PerfectFit" shifter is Keisler's custom design, and is physically relocated directly below the tunnel hole to give the shortest throws, which are also symmetric left to right and front to back. The Keisler PerfectFit" gives the best fit and shift quality of any custom Tremec solution on the market - Period.

Keisler ClassicFit" emulates the PerfectFit" shifter handle position, but the Tremec transmission is bone stock otherwise. With the Keisler ClassicFit", as with ANY bolt-on offset shifter, compromises are made to the overall result - mainly in the the amount of tunnel modification to fit the transmission case, the amount of the shifter hole modification, and shifter throws being slightly compromised because the pivot joint is on the centerline of the tunnel rather than being directly below the factory 4-speed hole. This is most important when converting a factory 4-speed car, and you don't want to modify the car any more than absolutely necessary.

The Keisler ClassicFit" shifter is designed to be the "best in class" custom offset bolt-on shifter at a price that is at or below comparable bolt-on shifter offerings from other companies.
