transmission pump shaft

[petedogg]

I'm planning on replacing the pump shaft and bearing when I replace the torque converter. I ordered the 96855-02K pump shaft and 96855-01K pump shaft bearing and seal from transmissionpartsusa.com, but didn't see any listing for the 4 seals that need replaced.

Is there any aftermarket source for the pump shaft seals that I need to replace, or do I need to go to the dealer? Do I need any special tools for putting the new seals on?

back-date the seals to an earlier year. 1 piece v. 2 piece

Why do I need to do this? Can you expand a little? Thanks for the reply.

two piece seals blow out easier, backdate to a one piece out of older trannies and its a one piece, less likely to fail
