Help us help you
Hi MBenner if you would go to the 'User Control Panel' button at the top of the forums page, go to 'edit profile' and fill in your truck info, and your location we can help you better.
I would recommend that you get the truck to a good diesel trans shop, one that does a lot of Dodge transmissions. Most dealers only replace full transmissions, and aren't very good at diagnosing problems on older trucks.
There are several different clutches in the trans, what is the trans doing or not doing?? Not shifting up? Shuddering?
If the fluid is still clear, it may be a seal problem, or a solenoid problem, hopefully not a burnt clutch pack.
PM me if you want. I will try to help.
