****** service question

[HoosierJeeper]

So within the next three weeks (one of which that the KJ will be parked), I've pondered getting a ****** service, as it's just about due for one and I'll be towing a 3500-4000 pound trailer from FL to WI. My question is that when the dealer reprograms it, and it relearns itself...I don't want it to relearn based on the one time occasion of towing the trailer. Is this a real concern? If it only needs 100 miles to relearn, I can do that around town without an issue.

Anyway, thanks in advance!

Anyone?

HJ, IIRC relearn isn't required for a simple pan drop, unless of course new parameters are flashed into the TCM.

Also, it seems that ATF+4 ir rather shear stable, so, changing just 5 qts won't change fluid's properties all that much.
Also, You probably know I'm in favour of doing that kind of job myself, but it's only me...
