A750-BOOST

Installation Instructions (English) 2003 and newer Toyota and Lexus vehicles equipped with A750, A760, A761, A960 and AB60 series automatic transmissions often wear out the line pressure boost valve and bushing. As a result, the transmission will not have the required main line pressure boost under load. Adequate main line pressure is required to provide enough clamping force under all load conditions to prevent slipping, as well as to achieve proper shift quality. Consequently, a compromised EPC boost valve and bushing will cause complaints of slow or lazy pressure boost, soft shifts, flare shifts, burnt frictions and burnt lock-up clutch can occur. These can also be accompanied by a wide variety of gear ratio, shift and solenoid performance codes. Features and benefits: The TransGo drop-in USA-made hardened steel boost valve and bushing assembly provides you with a durable direct replacement for the soft aluminum OEM assembly that is prone to wear. This kit restores hydraulic integrity, as a result line pressure boost will once again meet the OE specifications. Our drop in valves require no reaming or tooling. Corrects/Prevents/Reduces: Insufficient line rise Soft, slipping or flaring shifts Burned friction material TCC slip Codes P0746, P0751, P0756, P0771, P0776, P0894, P2714 and P2757 Includes: USA-made hardened steel boost valve and bushing USA-made hardened steel reverse boost valve Gold shim (for some applications)
