TH700 700-R4 4L60 Shift Kit Valve Body Correction Kit GM vehicles 1985 and Up
The common complaints and failures are: 2-4 band and 3-4 clutch failure, an unreliable TV system is the root cause of the band and 3-4 clutch failure as well as late or early shifts. Other complaints are 1-2 slide bump, 2-3 cut-loose, low/reverse clutch failure, no 4th or falling out of 4th as well as 4-3-4-3 shuttle shifts and the infamous 3-2 downshift bang with the lever in the D3 range.
Features and benefits:
This kit features our patented BOOTSTRAPÂ® TV system that cures these complaints and failures. Once the TV system was functional, the surrounding systems needed to be calibrated to work with the all new TV system.
