I have a 1992 PowerRam 250 Cummin's Turbo Diesel Intercooled w/ Automatic Transmission issues. What's going on is when I first start the truck cold, it revs up real high for about 3 seconds in drive before finally moving.( don't know the RPMs, no tach) Once it starts moving, it's fine for first gear, and second gear(shifts a little hard), but when it starts going around 50 mph, it wont shift into overdrive like it should (should shift into final gear at about 45 mph). It's topping about 52mph because it wont hit that last gear. It's an automatic diesel tranny and some stuff I found online mentioned compression and seals but I'm just not sure. Either email me or post on here if you have any ideas. I greatly Appreciate it.

Check out www.allpar.com Lots of MOPAR stuff on the site, maybe something that will help you. I've already posted everything I know about MOPAR automatic trannies.
