So we drove 4 hours for a mini vacation. Right before we got to our destination we pulled over for gas. The car was shifting hard. Tried to pull out of a parking spot and no reverse. Pushed it out and got back on the road with no 3rd and 5th. Reading over the forums it sounds like a wave plate. Took it to the local dealer and they said it is a faulty TCM. Quoted me $1,000 to replace. I got a rental out of my pocket and am now home. The car is at the dealer and they should be done with it on Wednesday. Then I get to make the 8 hour trip to get it and get back home. When they replace the TCM will they be able to tell if maybe the wave plate is bad also? If it ends up being the wave plate will I be reimbursed for the rental and the TCM? And more importantly would the TCM cover the wave plate problem long enough that I might get 2 hours into my trip home and get stranded in the middle of nowhere?
