Has anyone changed the transmission? I took mine to the dealer to have it checked out because it was not shifting and when it would it would be a hard shift from first to 3rd and then it would be stuck on either 1st or 3rd gear and would just jump around to all gear but would not advance at random times. It started off by feeling a hard shift from 6th to 4th on hard acceleration then it would squeal on 4th/5th gear under load but mostly in 5th. I also have a few codes on it P0741, P07AA and P1744. They told me to definitely found out the issue they would have to pull the trans oil pan and cut the oil filter, at this point from what I have found the torque converter clutch is pretty much bad also I have decreased mpg's. they quoted me $5417.00 plus tax to change the trans and torque converter. at this point I am willing to do it myself as I found a upgraded trans for half the cost pretty much. I am wondering if there is any advice on changing it thanks in advance.
