The kit also provides TCC regulator valve component options that will work with vehicles with or without active fuel management (AFM). Furthermore, the included drop-in USA-made TCC isolator and regulator valve features longer lands which restores the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of their bore.

These changes work in concert with a slight increase in line pressure to greatly improve the overall durability and shift feel of the transmissions. It includes components as well as modifications that recalibrates the entire accumulation system. The kit includes valve body, servo, pump and accumulator components and modifications designed to deliver increased durability while providing short smooth shifts as well as a more efficient TCC apply. The 3-4 clutch plate failure as well as the 2-3 flare up complaints are caused by an inconsistent pressure boost and poor overall calibration of the shift accumulation system.

The TCC slip code leads to the harsh 1-2 upshift as the ECM recognized the TCC slip and commands high line pressure to avoid further TCC slippage and damage. The torque converter clutch regulator valve bore is very prone to wear causing the TCC slip complaints and related code. Common complaints on this transmission are TCC slip or shudder, code P1870 or P0894, harsh 1-2 shift, double bump shifts, 2-3 flare up, burnt 3-4 clutch plates as well as inconsistent pressure boost problems. The TransGo 4L60E SHIFT KITВ® Valve Body Repair Kit fits 1993 to 2015 General Motors vehicles equipped with the 4L60E, 4L65E and 4L70E automatic transmission.
