Sonnax GM TH350 Intermediate Servo Sleeve Kit TH350C TH-350 TH-350C Automatic Transmission
OPT Product Code: SNX-35709-01K$54.62
Product Details
The intermediate servo bore becomes scored from repeated cycling. The piston, at spring side, is charged in R,N,D. Excess leakage at an idle results in delayed engagements and lowered line pressure. Oil loss during the forward operation affects shift quality and reduces clutch life. To make these cases usable again install the Sonnax Intermediate Servo Sleeve Kit 35709-01K. This kit contains an aluminum sleeve and a replacement piston with a Teflon seal. This kit is a simple drop-in solution and requires no machining of the transmission case.
