So i finally found a used 6R80 transmission that came from a 2012 4wd 5.0L F-150. (150k miles)
It cost $650+$200 core charge+tax
Changed the front seal.
Changed the filter and pan gasket.
Cleaned the pan, especially the magnet.
Blew out the cooler lines (reverse of fluid flow) with some compressed air.
Installed the transmission and put everything back together. Using anti-seize in many places.
Filled the transmission with Mercon LV. (5 quarts)
Started her up and let her idle for like 15 mins.
Holding the brake down I periodically shifted through all gears while waiting.
Took it for a test drive and it was in limp mode. (wouldnt shift out of first gear, but at least it was moving)
Took it back home to reset the computer.
Disconnected the Negative battery terminal, and using an alligator clip i connected the negative cable to the positive terminal that was still connected to the battery.
Waited 15 minutes.
After cranking her back up, she started shifting (rough, loud banging)
She was trying to learn the shift points since i reset it.
The more I drove the softer it shifted.
After getting back home with the trans temp at 190 I got underneath to check the trans dipstick.
Its very easy to burn yourself.
The Dipstick was dry.
Added 3 more quarts and the level was in the acceptable range on the dipstick. closer to the bottom. which is fine since i added 3 cold quarts, and the fluid expands when it gets hot.
Took her for another drive and shifting got even softer.
I'm still driving her easy. But im so happy to have her back on the road without paying 3k for a remanned transmission.

I had mine rebuilt in my 2013 raptor. The shop upgraded the shaft, which I had hewn into. Apparently the 6.2 produces too much torque for the oem shaft to handle. Mine now runs like Deon sanders in a wide open field after breaking six tackles
Look this thread is almost 2 years old and OP been gone that long almost. Glad to hear you got yours fixed to much torque on a stock 6.3 LOL.......Might be to much wheel hop. You cot a pic of this 2013.....Pics or it is a Prius
