For those of us who use Forscan, resetting the adaptive tables seems like quite a common thing to do.. however I just found out recently that there is actually an official relearn process straight from the Ford workshop manual you have to follow after the reset. I didn't know about this before, neither did many people I know with 10R80s both IRL and on forums/Reddit.

So this comes out of WSM, Section 307-01 which is also referenced in a number of TSBs related to 10R transmissions:

NOTE: Perform the adaptive learning drive cycle on a level road surface.

  1. Using the scan tool, clear the DTCs (Diagnostic Trouble Codes) and Transmission Adaptive Tables.
  2. Drive the vehicle until the engine and transmission reach normal operating temperature.
  3. Accelerate from a stop with light throttle (15%) ensuring that upshifts 1st through 8th occur at engine speeds between 1300-1600 rpm.
  4. Continue to accelerate (may apply slightly more throttle after 7-8 upshift at 32-38 mph (51- 61 km/h) until you achieve 55 mph (88 km/h) and the 8-9 and 9-10 shifts complete.
  5. Brake very gently to a complete stop and hold foot on brake for five (5) seconds.
  6. Shift the transmission to Neutral. Wait 1 second.
  7. Shift the transmission to Reverse. Wait 2 seconds.
  8. Shift the transmission to Neutral. Wait 1 second.
  9. Shift the transmission to Drive. Wait 2 seconds.
  10. Repeat Steps 3 through 9 six additional times.
I suspect that for some people where resetting adaptive tables helped briefly and then went out of wack, that this procedure may not have been followed, whether they reset the tables themselves or the dealer did it. As you can tell the process is quite cumbersome. I wouldn't be surprised if many dealers don't do this, especially if they aren't near a long, flat stretch of empty backroad. I'm sure people would get pissed off if they got stuck behind someone doing this. Not sure if dealers have special equipment that can do this for them, I doubt it and even the workshop manual says "level road surface".

I know some are of the opinion that you should just drive how you normally drive after resetting tables, but I have a feeling there's more to it- perhaps this cycle is crucial for the initial relearn. So I'm curious to know how many of you are doing this currently, and if it has made a difference for your adaptive transmission at all.
