Yes mu '00 F550 auto dose the same thing, going on 10K miles like this, I am having a PCM modded (by PHP)
to take care of this issue, I am also putting a 6 speed
(I hate automatics) in my F550, so I am not going to bother with the chip, since the modded manual trans PCM will fix it
I call the "jerk" drive line slap
I try not to let other people drive the truck, but I have not problems because I trained my self not to let it "slap" the drive line
Dose your truck push a little black smoke just off idle?
