Transmission problem Need Help!!!
2006 Dakota with a 545RFE
Whats going on is sometimes when I restart the truck after driving and go to shift when I barely move the shifter the indicator on the dash is moving to Reverse before actually shifting causing the transmission to go into limp mode. This never happens after sitting all night on the first start of the day and only happens after heating up. It's worse when the temps outside are higher and hardly ever happens when outside temps are below freezing. When it does happen it throws some code but off hand I can't remember what they all are but they all pointed to the TCM or solenoid pack. First I changed the TCM and had it reprogrammed at the dealership. That didn't work to this weekend I changed the solenoid pack and new filters and fluid and that didn't work either. No issues at all with the tranny when it's working right. Shifts smooth pulls great and when I dropped the pan the fluid was bright red and clean as could be. Magnet in the pan was clean also. Like I said, it never happens after sitting all night, only after driving and heating up. Sometimes you can drive a little and shut down and restart and it's fine. After a couple days the check engine light will go off. Only thing I can think of is trying to adjust the linkage that maybe it isn't shifting all the way to park but I would think if that's the case even after sitting all night it would do it then. Any ideas?

PO841.... This one came up twice
Thing I've done is check and replace the transmission relay, changed and reprogrammed the computer at the dealership, and changed solenoid pack and filters and fluid. Took apart all electrical connections and cleaned.

The battery has seemed fine. Never had any problem starting and when it's really cold outside the problem isn't as bad. When it's below freezing it hardly ever messes up but when it's hot outside like today it'll be fine on startup but once I turn the truck off after driving and try to restart before completely cooling down for hours then it'll mess up and go into limp mode.
