I'm working on a 2005, ram 3500 with cummins diesel engine and am having a concern with the transmission. Not real experienced with dodge trucks so any help troubleshooting would be appreciated. The symptoms are... transmission slow to hook up under initial acccelleration from stop (feels like its slipping a little) and also noticed when backing out of parking stall when shifted from reverse to forward, there is a harsh engagement (no cushion). Is there any adjustment to the bands on this transmission.

check the fluid, if it's kind of brown and burnt, you probably have a pressure transducer issue. it will feeling like it is launching in second gear. If this the problem, replace the transducer (56028196AD) and flush the system. hope this is helpful

Every newer CTD I've been in acts like this (with 48RE) ... mine is worse than most. Try plowing all day having to do this thousands of times each day ... brutal. Come to a complete stop and hold the brake FIRMLY is the only way to cushion it all.
I've had it checked out for everything they are allowed to do under warranty including the bands adjusted with fresh fluid and nothing ... talked to many tranny gurus to no avail ... learn to live with it I guess.

Oh, and replacing the governor pressure solenoid valve and transducer will do nothing for that ... they will help with shift-hunting (1-2-1-2 or 2-3-2-3) if you have that problem though. There is a TSB out for that.
