I have 2 of the outside part of the inside door grab handles in fair shape. PM me your address and I'll send them to you.
I haven't heard much about transmission issues or any shifting tails at all but make sure you put the right fluid in it...has to be JWS-3309 compliant. Cheapest may be Mobil-1 but you can also use Toyota Type IV (they're the same thing). I would not trust any of the "for all transmissions" type fluid at all! Also considering the miles on the tranny, I would not do any power flushing at all...personally I would do several drain and fills but there are differing opinions on how to replace the fluid that's already in there.
