I would like to say thanks for all the info, on here, regarding the 10R80 issues. I should have joined years ago. 2020 F250 Super Duty Tremor. Just turned 25k on the odometer, at a stop light, noticed tranny in 4th gear. I placed in park, back to drive, still in 4th gear with significant loss of power. Pulled into parking lot, switched truck off, waiting a couple minutes, turned engine back on, dropped in drive, went to 1st with the illuminated “wrench” on, that eventually went dark. I made it 18 miles home. I called dealership for appointment. Thankfully, I made it the dealership with lunging between every gear change. I was informed yesterday that service ran all diagnostic testing and took it out for a spin. Tranny crapped out on service tech 75 feet from dealership. Dealership called to inform me of tech’s experience and that I need a transmission replacement. Thankfully it is still under warranty. Off to get a rental vehicle until courtesy vehicle becomes available at dealership. Dealership stated they could not give me an estimated time of repair. Just wondering the time frame anyone experienced with total replacement at your dealership? Thanks!
