Thread: 2005 rpm going up and down

I am new to this site and have an extremely limited knowledge of the GP.....however, a friend of mine was having a similar problem with his dodge truck and a local transmission company told him the same thing. Same outcome as yours. In the end, it was a faulty transmission module (brain) that was the culprit. Hope this helps.

so did they put another trans in it or what happende in this sitution?
