    I have a 2002 Tacoma 4cyl 3rz with the W59 5 speed transmission. I just recently started to leak between the transmission and transfer case. I have been searching and googling but could not find the Toyota OEM part numbers for the transmission output seal and the transfer case input seal. So when I have time I'll drop the transfer case and replace these two seals. Any help with the part numbers would be great.

    Well after calling Camelback Toyota and talking to Mike these are the part numbers I was looking for
    90311-40021 transfer case input seal
    90311-40007 w59 transmission extension seal
    I hope this helps someone else in the future.

    Trying to order the right transmission mount now for the 2002 you had or have. I already received the wrong one knowing it was just a chance of getting the right one.

    When you replace the seal be very careful and lube the seal. I had to replace mine after I rebuilt my trans and it started leaking. Had to buy another and replace the seal with the trans in the truck. That Xfer case is HEAVY. very easy to lose grip and hit the seal as you are putting it back on.
