Keisler's T45RS Essentials Kit is for the budget-minded enthusiast that doesn't require the extra strength of the TKO.  It includes all the basic items that are required to install the T45RS-425 into your GM, Ford, or Mopar.

Optional Keisler ClassicFit™ Offset Shifter is also now available for many vehicles! It provides the same correct shift lever attachment point as our TKO PerfectFit™ series. Modification of the 4-speed shifter hole is required for some applications. (Note: If you desire minor or no modification, please see our TKO PerfectFit™ series of transmission systems).

Enjoy low-rpm cruising, great fuel economy, and less engine wear with the Keisler T45RS-425 5-speed overdrive!

NOTE:  This transmission is not a direct bolt-in, and will require modification to your driveshaft, crossmember, and possibly your transmission tunnel.

Drivetrain component selection and installation instruction and support is critical to get the job done right. Rest assured, buying from Keisler - the leader in manual transmission systems - is the first step in the best driving improvement you will make to your vehicle.
