Been out of town for awhile. I'm not sure if they are. Call Mary Ann at Ed Morse Chevrolet and ask her for the part numbers. That's where I get my parts. I think they would be... I can't think of a reason why they would be different. If you get stuck, the guys at West Pines Service Center can do the work for cheaper than the dealership. I work with those guys on some projects.

Hi joe I live in Miami and just got a 1998 c5. I wanted to fix a leak on the diff and now have the whole rear end almost out and going to rebuilt the TT. I saw your post on the part numbers for the bearing and seals are they the same for an automatic. Thanks for your help hope you don't mind the question.
