Do you have questions about which package to choose?
Check out our guide on Tremec Transmissions. We cover everything from the basics to the nitty gritty details!

* Please note that the above packages do not include hard parts (non-wear items). This includes gears, sliders, and shafts. The necessity of replacing these parts is determined on a case-by-case basis. Your transmission will need to be disassembled and assessed in order to know what, if any additional parts are necessary to get the unit back to good condition. The most common problem is worn engagement points on the gears and sliders. This doesn’t necessarily cause obvious issues, unless it has gotten really bad. We recommend replacing parts to where the unit will be better-than-new once completed.
