As various transmission components wear over time, front unit endplay can stray from specification. Replacement of assorted parts will similarly modify endplay settings. Sonnax selective thrust washer 77409-16 (.094" - .098" thick) allows the rebuilder to correctly set endplay for 4L60, 4L60-E, 4L65-E and 4L70-E units. Sonnax shim 77409-15 (.015" thick) can be used as well for further endplay fine-tuning.
