My 90 350 SDL has been slow to shift in reverse for a year now. Everything else is fine. I figure with 260K on the tranny it is time to pull it and rebuild. I have rebuilt a few 727 Mopar tranny's in my younger days without any problem. Question: are there any special tools/problems or extra parts I need to buy other than the standard tranny rebuild kit? If one of you has done this before any helpful hints will be appreciated.
