Boostvalve HP TH350

Boostvalve HP TH350 Sleeve Reverse & Modulator Boost Valve Intermediate Boost Valve The OE boost valve sleeve wears out from the reciprocation of the steel valve within the aluminum sleeve. Wear in the reverse boost sleeve results in low line pressure, soft 1-2 and 2-3 shifts and/or reverse engagement or shudder. Sonnax offers 35754-01K, a high performance boost valve and sleeve replacement. This high performance boost valve and sleeve incorporates a larger boost ratio, which increases line pressure and provides firmer shifts. It is also recommended for street/strip performance vehicles. Redesigned sleeve prevents sticking Larger boost ratio No machining required
