Unfortunately the one they sent me did no fit. It was larger than the original that was in my transmission on 2001 isuzu rodeo.

Ordered this and you get 2 seals in the bag, perfect to rebuild the 2 accumulator pistons that are accessible from the pan. Just remember to scuff the piston's path with scotch - bright green scouring pad. Same as the one you use for dishes. A+++++Fixed my long-shifting on my 4T65E-HD W-Body V8.
