This TransGo 700-JR SHIFT KIT® Valve Body Repair Kit fits 1988 to 1993 General Motors vehicles equipped with the 700R4/4L60 automatic transmission. This kit was designed for the 1988-1993 units with a type two valve body. For the type one valve bodies 1982-1987 use #SK 700.
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 BOOTSTRAP® 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.
