Normal component wear allows excess forward and direct drum travel. This travel or free-play reduces sealing ring life. The 400 and 4L80-E are limited on the thickness of pump shim material that can be added. Excessive shimming at the pump will push the forward drum off the rings and result in a burned forward clutch. Sonnax offers a .010" thick shim, 34500-Z, that can be stacked under the sun gear bearing race. • By lifting the sun gear, the drums are also supported and front unit endplay is reduced. • The shim can be installed between the sun gear thrust bearing and the rear internal gear during lower unit assembly. • Updated design fits all model years Symptoms: • Burnt Forward clutch • Excess front endplay • Excess rear endplay • Premature seal ring failure Cause: Normal component wear allows forward and direct drum travel, resulting in excessive endplay Correction: This unit endplay shim allows for proper setting of front unit endplay and supports the direct drum by supporting the sun gear. NOTE: Updated design Tang Style Shim can now be used on all units, including 4L80-E 97-later End-play shim TH400 was added to your shopping cart. Shopping Cart »
