The truck had around 120,600 miles and had at least one previous fluid and filter change in the past. The fluid was not burnt or dirty. It was still in really good condition in my opinion. It did have a little bit of clutch material in the pan but not a lot or any large pieces. The magnet in the pan had some metal shavings on it as well but again not an excessive amount. Previous to the clunk and limp mode the transmission was smooth and flawless. It shifted smooth up and down through the gears and had never had any signs of slipping or sluggish shifts. This all came about instantly. I am wondering if the TCM or maybe if there's a relay other than one under hood in fuse box that could be bad? Also the governor pressure switch and input/output speed sensors if they could cause the issue? I am buying a 2002 Overland with the H.O. 4.7 this Saturday it has been rolled but runs and drives with no check engine lights. If I haven't gotten this figured out by then I am considering swapping the valve body solenoid pack any sensors and TCM into this one and see if that fixes it. If not I will swap in the whole unit but I don't think the transmission itself is the issue but then again who knows. Will the TCM from the 2002 work in the 2004 if I want to try that as a possibility?
