This kit is a favorite of professional transmission rebuilders worldwide. Finally, the difference in driving characteristics once the kit is installed is remarkable. 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. Presents: Fallow along as I get the last piece of the transmission together.

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 self-sufficient repair of the automatic transmission can’t be carried out.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. Dismantling transmission is time-consuming task, which is made only under the force of the special equipment.

Transmission 4L60E problemsĪt the same time, it must be said that due to the increased sizes the repair of automatic transmission 4L60E of this modification is more difficult. It means that you can repair the automatic gearbox GM 700R4.

If casting number on inner recess of servo piston housing is missing or illegible, measure to determine which servo is in use (Figure 1).

It differs by reliability and reparability. Sonnax servo release check valve comes ready to install in units with OE servos with casting numbers 8642554, 864259159. Altogether thes automatic gearbox makes a positive impression. It should be noted that certain functions of modification of transmission are controlled by electronics. This required the use of updated and enlarged in size solenoids. To ensure high-quality transmission’s lubrication solenoids channels were significantly increased. A principally new four-speed automatic transmission 4L60E was developed, which got a reinforced hydro block and a special pump’s design that allowed in a high-quality way to ensure engine lubrication. In the early 90s there was a problem of development of a heavy-duty automatic gearbox, which could be used in the Hummer cars equipped with the powerful petrol and diesel engines.
