Output Shafts:

The TKO-500 and TKO-600 transmissions have the stronger 31 spline C6 output shaft. This is true for all applications.

Input Shafts:

• All TKO-500 and TKO-600 transmissions have the 26 spline 1 1/8” input shaft
• We also offer varying input shaft lengths for various applications.  For example, the 3rd gen GM F-Body requires a longer input shaft. And we offer custom input shaft lengths for FE Ford, Mopar, etc. Call for details.

Shifter:

Standard on this transmission is a high performance billet aluminum short-throw shifter that can be positioned at 16.75” or 19.5” ! It’s a specially designed shifter with an isolator to reduce road noise. It also has a unique biasing system that is adjustable to accomodate varying driving preferences.   As with all TREMEC transmissions, the shifter stops are internal, eleminating the need for external stops. Use 8mm bolts for the shifter bar.

With Forte’s custom shifters, there are 8 different shifter location options!  They are as follows (all measurements are in inches from the front face of the trans):
