BEFORE YOU BUY

Confirm your transmission uses the auxiliary valve body style and a 30-spline input shaft before ordering. When in doubt, verify by casting/valve body type rather than year alone.

FINISH THE JOB RIGHT

Add Lubegard Platinum Universal ATF Protectant to your order - it helps protect seals, reduce operating heat, and extend the life of your freshly rebuilt transmission.
