TCI 374400 - TCI Throttle Valve Sleeve Kit for TH700-R4

Replaces stock assembly to prevent part-throttle downshifts from fourth to third gear until approximately 85% throttle has been applied (most OE setups force a part-throttle downshift around 50% throttle opening). Proper downshift performance can also be restored by replacing a worn, stock assembly. This kit uses existing OE plunger.

Note: Does not fit 4L60E or 2004R transmissions
