Product Description
GM TH400 Transmission Valve Body Shift Kit
by Superior Transmission Parts
This shift correction package offers the option of regular and heavy duty applications all in the same kit. This valve body kit supplies metal rings for the 2nd accumulator. This one is for the model years that used Telfon rings. Teflon rings in this application did not perform well. The 400 kit comes supplied with a thicker heavy duty snap ring for the intermediate clutch. The stock ring blows pas the lugs in the case which in turn leaves the case with broken lugs. With the specially engineered Superior snap ring, cases with 2 to 3 broken lugs can be used with no fear of failure.
