Installation Notes and Tips

Verify transmission number and application notes before installation, especially on listings marked “From Trans. Number 278040” or “Only Fits” specific transmission families such as 30RH, 31RH, 32RH, A904, A998, and A999. Clean the sealing surfaces thoroughly and inspect the extension housing and case for wear, nicks, or contamination before installing the new O-ring. Confirm the position matches the vehicle listing, since this part is used in N/A and Inner configurations depending on application.
