TransGo SHIFT KIT® Valve Body Repair Kit for A340, A341, A343, Jeep AW4 4SPD (1985-ON)
Product Overview:
This 340 SHIFT KIT® Valve Body Repair Kit is designed for 1985 and newer Toyota, Lexus, Isuzu, Mitsubishi, Hyundai, Kia, and Jeep vehicles equipped with the A340, A341, A343, and AW4 series automatic transmissions. Common issues with these transmissions include rough shifts when cold, soft shifts, sluggish kickdowns, TCC slip, and overheating.
Key Issues Addressed:
One of the primary causes of these issues is a worn-out TCC relay boost valve and bushing. When these components wear out, they can lead to lock-up control problems and overheating. Other shift-related complaints often require recalibration of the accumulator springs, pressure regulator spring, and the orifices in the valve body separator plate.
Features and Benefits:
- Includes a drop-in, USA-made hardened steel TCC relay boost valve and bushing, restoring hydraulic circuit integrity for type two, three, and four valve bodies (excluding some Lexus models).
- This hardened steel assembly is a durable replacement for the original soft aluminum OEM parts, which are prone to wear.
- Comes with everything needed to recalibrate accumulators, separator plate feed orifices, and pressure regulation, leading to improved shifting and greater transmission durability.
