| Reprogramming Kit; With Gear Command; For 4L60E, 4L65E, 4L70E, 4L75E Transmissions |
| This 4L60E-HD2 Reprogramming Kit fits 1993 to 2015 General Motors vehicles equipped with the 4L60E, 4L65E and 4L70E automatic transmission. 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 torque converter clutch regulator valve bore is very prone to wear causing the TCC slip complaints and related code. 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 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.
Features & Benefits:
This TransGo Reprogramming Kit includes valve body, servo, pump and accumulator components and modifications designed to deliver increased durability while providing firm shifts as well as a more efficient TCC apply. It includes components as well as modifications that recalibrates the entire accumulation system, clutch and band feed orifices. These changes work in concert with an aggressive line pressure curve to greatly improve the overall durability and shift feel of the transmission. . 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. Lastly, on 1993 to 2008, the gear command feature will allow for full gear lever controlled downshifts 3rd through 1st gear as well as holding manual 1st or 2nd gear to any speed or RPM.
This kit can be installed while the transmission is in the vehicle on 1993-2006 models only without the input speed sensor. 2007 and later models equipped with the input speed sensor require transmission removal. This kit also includes 7CS 3-4 clutch piston return spring kit for the input drum which reduces centrifugal 3-4 clutch apply and failure in 1st gear at 5500 RPM or higher, transmission removal required.

TransGo Shift Kit vs. Reprogramming Kit
Shift Kit® -- DESIGNED FOR DURABILITY
TransGo Shift Kit® valve body repair kits correct, prevent and reduce multiple transmission problems such as shift irregularities and durability issues. These kits are designed for normal everyday use and light duty towing.
Reprogramming Kit -- ENGINEERED FOR PERFORMANCE
TransGo Reprogramming Kit™ valve body performance kits are made for Heavy Duty and/or Performance applications, and include additional features such as:
- Gear Command™: Allows full control of downshifting and will hold any gear to any RPM. Retains automatic up shifts in the drive position. Certain units allow manual up shifts on driver command.
- Manual Shift Control: This feature fully converts the valve body to manual/stick shift operation – no automatic shifts. Most Manual Shift Control kits also allow you the ability to easily convert back to automatic.
- Tuneless: Patent-pending internal calibration technology “tuneless” allows install without the need for additional transmission tuning software or programmers.
