T45RS-350 Essentials Kit (350 LB-FT)

Overview-Ordering

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-350 into your GM, Ford, or Mopar.

Optional Keisler ClassicFit™ Offset Shifter is also now available! It provides the same correct shift lever attachment point as our TKO PerfectFit™ series.

Enjoy low-rpm cruising, great fuel economy, and less engine wear with the Keisler T45RS-350 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.

Robert Kostash - '69 Camaro RS Yenko Pro-Tour


The shop that completed the Pro-Tour project has used Keisler 5 speed and 6 speed kits numerous times...they were keen to do another Keisler TKO600 for my car.  I also highlighted the progress through the winter on Pro-Touring.com. The car now drives just super, with the tight shifting Tremec.  I just love the overdrive!

Joseph Coppola - '67 Camaro


You made my Camaro a real fun car to drive again.  I have had the car for 20 plus years.  I have been a racer and builder for years.  Six years ago, I started building the car again with my son.  I wanted a car that could be auto crossed and driven every day.  It has a built 383 dfi injected motor, TKO600, chassiworks front clip, and hotrods to hell 3 link in the rear along with a bunch of other trick things.  All the work was done in my garage.  I had a good jw's trani in her, but tough on the street and no good for auto cross.  Since putting in your trani kit, I can drive it anywhere.
