best shift kit?
#5
I would recommend that you install the modified TransGo Perfomance Shift kit. This will upgrade the main boost valve for more main line pressure when needed, smoother part throttle shifts, better stabilized line pressure, slightly quicker 3-2 downshift, & firmer WOT shifts. This modified TransGo Performance Shift kit has been installed by hundreds of people successfully. What year is the transmission that the Shift kit is going into?
