I ordered the seals that I thought were correct for the leaking transmission in my 2001 LT. Now I'm not so sure that I have the correct seals. Is there anyone out there who has done this job on a pre 2004 LT that can tell me the PNs of the seals they installed? Signed; Confused LT Owner

Why do you think you have the wrong seals.
They should look like the ones in this picture along with the nuts bolts Viton o-ring thrust washer etc necessary to do the job.
