Did a search, couldn't find anything. Just bought a 94 Cummins with an auto with overdrive. When the tranny is warmed up it seems to surge in and out of OD. It's almost like the converter doesn't want to stay locked? Newbie to Dodges, anyone have any ideas?

i have a 99 that did it also and i just changed the fluid and the filter and it stopped, a buddy of mine had a 99 also and changed the tcc and that fixed his.

johnny5 where was that bad ground?

Great white, tcc?

Thank you all for your input!!!!

the bad ground was on the front of the head near the intake

For the archives....I cleaned the ground wires on the front of the intake and the problem went away. Apparently this is the ground for the throttle position sensor. Thanks for the help.
