4T65E Automatic Transmission Valve Body Repair Kit

The TransGo SK4T65E SHIFT KIT® Valve Body Repair Kit is engineered to enhance the performance and durability of General Motors 4T65E automatic transmissions, compatible with models from 1997 onwards. This includes specific fitment for the Volvo 4T65E and the TipTronic transmission variant, often found in vehicles like the Pontiac Grand Prix. It is designed as a direct replacement for worn components, aiming to resolve common transmission issues. This kit offers a straightforward solution to improve drivability and reduce the likelihood of repeat failures. It features a new TransGo pressure regulator spring to ensure stable pressure, along with new accumulator springs and spacers to shorten shifts without introducing harshness. A new boost valve replaces the typically worn original, contributing to the transmission's overall longevity. The inclusion of a new, self-expanding 3rd clutch seal further enhances durability. The SK4T65E kit is specifically designed to correct and prevent problems such as codes P1811, P0741, and P0894. It also addresses common driver complaints including long or hard shifts, chatter during acceleration, and the absence of 4th gear or lock-up. Installation is recommended for experienced technicians and generally does not require transmission removal for most models, with no special tooling or machining necessary.
