  3. 10r80 harsh downshift after tune

    have a 2018 Ecoboost 10 speed and this transmission is annoying the heck out of mešŸ˜‚ I am at 58k miles and I got a transmission replacement about 1k miles ago. The car was shifting smooth but as soon as I put a tune on it, downshifting from 4-3-2-1 is super harsh. I got my tune from tune+ and he...

  5. Fluid change on 10r80 tomorrow… Advice?

    Tomorrow I will be attempting to change the transmission fluid & filter on my ā€˜18 GT Premium Convertible PP1 with the help of my father. We are both used to Toyotas and Iā€™m still somewhat new to Fords as of this Mustang being my 3rd over the past 2 years. We are both very aware of what we are...
  6. Ford Manufacturer Buy Back Experience

  8. 10R80 fluid (37k, 4-5 hpde + some autoX)

    I was really surprised by how the dipstick looked vs how it looked drained. Im changing the fluid and filter hoping it helps temps on track. Iā€™ve hit 255ish after pushing and the temps accelerate upwards based on how hard you drive it. Other than temps on track Ive had minimal issues. Every...
  9. Aftermarket 10r80 Transmission Cooler Issues?

    I have a 2018 10r80 and been through 3 transmissions already, still max effort N/A. First transmissions went out when the stock torque converter input shaft bushing got cooked. Put a used 10r80 in from a wrecked car with a Circle D 3800 stall converter and added a mishimitto cooler from a 15-17...
  10. Factory EcoBoost 10-speed tuning - better than GT/PP1 when it comes to downshifting, especially the 3>2 & 2>1?

    So, my '22 GT Premium PP1 (Active Exhaust + Magneride) 10-Speed is in the shop today (A/C compressor took a shit), and so they gave me a rental ecoboost 10-speed. So, I slapped it into Sport +, dropped the shift knob into "S" so that I could lock the paddle shifters into manual shifting mode. I...

  15. 10r80 5th gear issue

    2019 Mustang GT 10r80 about 36k miles. I have this weird hesitation in 5th gear all the time where it shifts into 5th then the rpmā€™s climb up then drop 200-400 and then go back up and shift like normal. You can hear it in the exhaust as well and sorta feel it. I read in another fourm that the...
  16. 10-Speed Automatic Transmission (10R80)

    Please chime-in if you have a 10-speed automatic or have direct knowledge about this issue. Any "whining" sounds? Low, moderate, loud? My brand-new 2023 has this "whining" sound at a moderate level. Sound is there in the morning, afternoon, evening, etc. Cold start, warm start, etc. Most...
  17. What is wrong with my car? Bad U-Joint? Bad Differential/LSD?

    Hi Everyone, Although I love my 2018 S550 Mustang GT very much, I've had my fair share of issues during these few years with it. Things from premature speakers crackling and seat cooler failing to multiple 10r80 transmission issues and eventual total trans replacement. Luckily, these have all...
  18. 10r80 bad slipping

    So I have a 2019 Mustang GT with the 10r80. Long story short. Had torque converter shudder. Got the converter replaced. Trans made super loud not normal noises when cold. Was told the new converter was faulty. Converters were on backorder no ETA. Ended up getting a whole new Trans with the good...
  19. 10r80 Trans issues

    I have a 2019 Mustang GT 10r80 about 30k miles. Had the converter replaced about 2-3k miles ago. Ever since I got it back from the dealer it has been making these noises. In my opinion it sounds like some bearings or the trans fluid pump. Only does it when itā€™s cold on a cold start. I would love...
  20. Boosted 10r80 Drivability

    Hi everyone, I have a @beefcake special supercharger kit, Vortech V3, tuned by Lund. Prior to this car was bone stock and these issues never happened. I had gotten the kit installed, after the tuning was done, I went to go test it out a bit, noticed my paddle shifters had a huge delay on them...
