Follow-up on the Ford trailer brake controller install. Pretty sure there was an ECU flash or something performed as part of the install at the dealer. I never read the instructions since I wasn’t installing, but if they flashed it I feel like they should’ve told me.
I say this because the transmission was ROUGH for a few days following the work. The dealer didn’t drive the truck at all. Had the same mileage when I picked up as when I’d dropped off.
After about 500 miles the transmission is smooth as butter again. So I’m guessing it was in its adaptive/learning mode.
So anyone else considering the Ford trailer brake accessory, I recommend asking if there’s an ECU flash involved if you’re having your dealer do it.
