I cracked open the TCM, and cleaned it out inside - it also had corrosion there. Reverse now works, and when I first start out, the tranny goes back to normal - but soon enough TFP returns... so now I'm a bit stumped. It does start to stutter around 60 km/h, and after 5 sec or so of that, once I slow down - then TFP turns on and I'm back to 3rd gear only. I need to get the OBD read again, me thinks - I hope there's something to go by... any thoughts, anyone??
