Got the Tiger home and drives like a dream. Spent a good hour with the transmission shop owner, mechanics and a box of parts that came out of my tranny. We went over each part and it appears that trans was just old and tired. No heat damage other than due to clutch wear they showed some slipping that would cause additional heat. The torque converter was clean and showed no heat damage aswell. The "suncage?" Also was clean with no color distortion. It also turns out that 1995 was the only year for this particular 4l60e, so they rebuilt this one versus just swapping a refurbished trans. It sucks to have to deal with this, but since it had 170k on it and I have no idea what the two previous owners did with it, this now gives me a peace of mind for our future trips. I will be adding a larger radiator, trans temp gage and a trans oil pan cooler to keep this thing long for a long time! See ya on the trail?
