This will be the “official” 10R80 thread. It contains Facts and links to other important 10R80 posts on this site.
10R80 “newbies” - if you just bought a new or used S550 w/10R80, scroll down to all of the “facts” and review the attached PDFs. This thread contains a TON of info for you newbies and helps you to understand the characteristics, inner workings of the 10R80, how to use the Trans Modes vs. Drive Modes, and paddle shifting info.
It will also serve as a repository for those who have had issues with their 10R80, were able to get resolution and so those owners can post what they or their Service Center did for resolution. Hopefully it will also help others possibly get resolution who may have inexperienced Service Centers.

The known S550 10R80 issues (does NOT affect all S550’s equipped with 10R80’s):
1) Harsh, clunky or jerky downshifts - usually most present during the 4-3, 3-2 or 2-1 downshift in Normal trans mode and can be more harsh when in Sport trans mode.
2) Harsh, clunky or jerky upshifts - usually most present during the 3-4, 5-6 upshift in Normal trans mode and can be more harsh when in Sport trans mode.
3) Stuttering of shift points when coming to a stop or accelerating. It feels like the trans is unable to determine which gear to go into as the RPMs are increasing.
4) Lack of initial engagement into from Park into Reverse if exterior temps are below 50*.
5) Lack of engagement from Park into Reverse when car is totally in normal temp range (190*-210*), regardless of exterior temps.
6) Extremely harsh engagement from Park into Reverse OR from Reverse to Drive (1st gear). Exterior temps do not matter. The engagement can be so harsh that it feels as if the car has been hit by another vehicle or like the driveline will rip the rear from the car.
7) Erratic shifts - seems like the trans is hunting or prematurely auto shifts gears when it should not be doing so.
8) Trans seems to remain in a higher gear when slowing down as vehicle MPH is decreasing when trans should actually be going into an obvious lower gear.
FACT 1 (Ford Trans Fluid notes):
Per Ford:
Use only Motorcraft MERCON® ULV Automatic Transmission Fluid XT-12-QULV (WSS-M2C949-A) or equivalent when servicing a 10R80 automatic transmission.
FACT 2 (10R80 SSM/TSB's):
The early 2018 S550’s w/10R80’s did have some operational issues with software and hardware. These issues (some minor and some major) were addressed by Ford through TSB’s or SSM’s. The link below contains ALL such info and docs as of today’s date. That thread gets updated when there is any new release of such info.

FACT 3 (Adaptive Learning Info):
The 10R80 is an adaptive learning transmission. The below thread contains the information about how to reset the adaptive learning of the 10R80 based on M6G Members and Ford’s recommendations (Post # 15 has the Ford Shop Manual info - thanks goes to @DickR):
https://www.mustang6g.com/forums/threads/question-on-10-speed.105430/#post-2702026
Adaptive learning can also be reset via Forscan for those who use the tool (thanks goes to @Blown86GT):
https://www.mustang6g.com/forums/threads/changing-valve-body-startegy-in-forscan.170382/
FACT 4 (LOW FLUID & DIPSTICK info):
M6G Members with 10R80’s have found that their 10R80 was low on fluid from the factory. If you suspect your shifting issues may be due to low fluid level, have your Ford Service Center check the fluid (or you can DIY at home with car safely jacked up or on a lift). Here’s 2 low trans fluid threads:

https://www.mustang6g.com/forums/threads/2018-10r80-dipstick.136868/
FACT 5 (Powertrain Warranty):
The Ford Powertrain/Drivetrain Warranty is 5/60. The transmission is covered under this warranty even if the new car 3/36 is expired.
__________________________
My 2018 was at the Ford Service Center in January 2020 for 10R80 shifting issues. Up until 2 weeks ago and since the car was purchased new, I didn’t have any shift issues up until 35k. The issues were resolved and here’s the complete Tech diagnosis and resolution. The trans no longer has any harshness, clunkiness or shift issues in any Trans Mode, Drive Mode or when shifting from Park to Reverse or from Reverse to Drive (1st gear). Even when slowing down and coming to a stop, the 10R80 shifts are flawless and it’s almost hard to tell the trans is even downshifting.
IMPORTANT NOTES:
1) Disconnecting the battery and/or resetting vehicle KAM will not update the trans software. It will not fix any issues IF the abnormal shifting is due to internal mechanical malfunctions (ie: valve body, torque converter, clutches, etc.)
2) If the 10R80 is “reflashed” with the most current software strategies by a Ford Service Center using IDS AND the abnormal shifting conditions remain AFTER a genuine trans reflash - the issue is NOT software related, it’s mechanical. Even with the trans being an adaptive learning trans, after an IDS software update and if the Tech has already performed the “relearn strategy”, when the Customer receives the car back - the trans should NOT have any harsh or abnormal shift conditions at all. If your 10R80 still has shift issues after a software reflash, it’s definitely a mechanical issue; print the above Tech notes and tell your Service Center they must do a similar diagnosis BEYOND just a test drive or software reflash.
