It can be difficult to reduce C6 unit endplay with spline or sunshell wear. When driveline wear is excessive, sealing ring and thrust wear increases. As the lower unit wear increases, OE selective thrust washers are not thick enough to compensate. Rebuilders often try to correct excessive endplay by adding thicker shims to the pump surface, but adding too much shim material to the pump area will push the sealing rings toward a minimal drum contact. Sonnax offers shim 36428A-Z to compensate for driveline wear.


  • Driveline clunk
  • Rear component driveline wear
  • Reduced seal ring life
Excessive total unit endplay
These Sonnax shims allow for proper setting of unit endplay and support the direct drum by supporting the sun gear.
  • 36428A-Z is a 4-slotted, .010″ thick shim to be used between the 4-tanged thrust washer and 4-pinion rear planetary.
  • These shims, together with OE thrust washer material, will allow precise endplay adjustment.
