The newest addition to our extensive line of TCI high performance components, these two servo kits will enhance shift quality and extend durability of any 700-R4/4L60E/4L65E. Since the servo applies the 2-4 band in 2nd gear, releases it in 3rd and reapplies it in 4th, the servo plays a vital role in the operation of your transmission.

The TCI Part #376005 kit includes two CNC-machined, 6061-T6 billet aluminium pistons, seals and hardware necessary to give your servo 35% more 2nd gear apply area than the commonly used,stock Corvette-style servo. The Part #376006 kit contains a large diameter 4th apply piston and matching cover, also machined from 6061-T6 billet aluminium. The piston utilises a lip seal to improve fluid retention, and the increased surface area will assure that the band is held tight under the most severe conditions.

Easy to install with transmission in the vehicle. Kits may be usedindividually or combined to create the ultimate servo for your 700-R4/4L60E/4L65E transmission.
