Spoke with my mechanic and he recommends that I replace all 4 transmission solenoids. I took the rig in to have the birthfied(sp) repacked per his and everybody here's recomendation. The trannny seemed to work fine before I took it in, before I left with it he says to me that I need to have all 4 solenoids replaced job cost $800
Anyways now the rig gets stuck in first gear which it didn't before I brought it in to him. Am I being scammed, is there a way the guy did something to my tranny to make it get stuck in first gear. I'd appreciate any feedback on this situation it would help if I was better inform before I plunked down more cash.
Thanks in advance
