Part #: SK 4L60E

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.
