SK 4L60E
Fits General Motors 4L60E, 4L65E and 4L70E 1993-2010 "Except Hybrid units".
Includes our exclusive "ISO-CONV Valve" a one piece valve that replaces both the OEM Isolator and Converter Regulator valves. This transmission has been utilized in many different vehicles and our kit contains parts and items necessary for an extensive recalibration of this unit regardless of vehicle size, power, engine or axle combinations.
Addresses and Fixes trouble Code 1870. Trouble light & Hard 1-2 shift. No lockup and/or 4th. Corrects damaging harmonic extreme bounce in pressure gauge readings on PWM (Pulse Width Modulated) pump that causes pump failure and/or premature wear on valves and pump assembly. A no fuss solution! Convenient drop in ISO-CONV valve, No special tooling or machining necessary!
This kit is a must for this transmission, not only does it shift quick, clean, smooth and nice, but it addresses the most serious complaints that have plagued this unit over the years. With this kit durability and dependability are greatly increased, plus you or your customer will love the way it works.
For Performance and Heavy Duty vehicles use the 4L60E-HD2 Reprogramming Kit™. It has all the benefits of the SK 4L60E kit plus options for firmer shifts and our exclusive Gear Command feature.

Transmission removal necessary: No
The TransGo 4L60E SHIFT KIT® Valve Body Repair 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 and benefits:
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. It includes components as well as modifications that recalibrates the entire accumulation system. These changes work in concert with a slight increase in line pressure to greatly improve the overall durability and shift feel of the transmissions. 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. The kit also provides TCC regulator valve component options that will work with vehicles with or without active fuel management (AFM). Finally, the difference in driving characteristics once the kit is installed is remarkable. This kit is a favorite of professional transmission rebuilders worldwide.
