Shift Correction Package
This valve body kit deals with these problems: * Soft late shifts * Soft 2-3 shifts * Harsh reverse engagement * Clutch chatter * Bind up in manual low when hot * Heavy duty snap ring for intermediate clutch * Works with 6 and 7 check ball cases * Includes new separator plate to replace worn out O.E. plate
1. This Shift Correction Package offers the option of regular and heavy duty applications all in the same kit. 2. This valve body kit supplies metal rings for the 2nd accumulator. This one is for the model years that used teflon rings. Teflon rings in this application did not perform well. 3. The 400 kit comes supplied with a thicker heavy duty snap ring for the intermediate clutch. The stock ring blows past 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.
Note to purchasing: Ask for Superior part number K400-WP.
