904 output seal

Get the PK number off the side of the trans pan rail above the neutral safety switch and contact someone with a mopar parts catalog. A lot of dealers don't have the old catalogs anymore. Get the oem number which will probably superceded about 15 times and get the latest number. Cross at any auto parts place and see what you get. Looks like you are getting a 727 seal You may have a different tail shaft on the trans as well. No numbers on the old seal?
