HEY HEY HEY! i finally fixed my transmission issues with the "bucking" at 40-50mph. i tried cleaning the grounds, i tried the aluminium foil thing. it never was totally fixed it only worked every now and then. I took it to a guy out here that works for dodge and he cut the grey connectors (2 of them) on the ground comming off of the pass battery. one going to the alt one going to the wall mounted pcm. he cut the connectors and sodiered the connection. WORKED LIKE A CHARM!!!!!!!!
