Transmission Components

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

The TCI® Part #376005 kit (left) includes two CNC-machined, 6061-T6 billet aluminum pistons, sealsand hardware necessary to give your servo 35% more 2nd gear apply area than the commonly used,stock Corvette-style servo. The Part #376006 kit (right) contains a large diameter 4th apply piston andmatching cover, also machined from 6061-T6 billet aluminum. The piston utilizes a lip seal to improvefluid retention, and the increased surface area will assure that the band is held tight under the mostsevere conditions.

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