Transmission leaking/irregular shifting😕
Hey everyone, I am new to here so forgive me if I am missing any information.
Anyway I have a 2001 F250 7.3l 4X4 supercrew 8 foot bed. Have an upgraded turbo, 4" exhaust from turbo back, k&n cold intake. Has 207,000 miles on it, 198k from first owner, the rest from me. Anyway the transmission is a automatic R4100 tranny. Since I have owned it it would shift from 3rd to 4th on slight grade. It would continue to shift up and down till I got back on flat again, rpm's would not vary to much depending on the grade. So that problem continues and now today I was towing a 14' trailer with 3 wheelers on it and I smelled smoke. Pulled over and it was pouring oil from the bellhousing. I had no choice but to drive back home about 20 miles. I first stopped and poured 2qts of ATF fluid in and then babied her home. What are my options here, any ideas on what I should be looking for to fix? Any help appreciated!!!

I am far from a transmission expert, but it sounds like it got hot. There is some good information in this post https://www.ford-trucks.com/forums/1...-problems.html
Looks like it is similar to your situation, in that they can get hot and push the fluid past the seal behind the bell housing.
I thinking all the shifting is one clue to look into for creating heat.
