Product Description
A TransGo reprogramming kit for A904, A727, TF6 and TF8 three-speed TorqueFlite transmissions, with and without lock-up, in the aluminum case.
It targets shift-quality complaints on these 3-SPD units: bind-up between second and third gear, converter shudder, leaks at the vent or lever seal, and pump bushing wear from drain-back. The kit includes a re-engineered manual valve and an uprated rear servo spring for a firmer manual 1-2 shift.
