I thing I noticed is that you dont mention any city driving,thats what your missing.I use 2 do relearn on older Chrysler trannys,and I would take them in the city,start from a stop,then start in 1st and shift it easy into every gear.Do this several times.Let it downshift by itself.Do this several times.Then go on highway,start with lower speed like 50,drive it for a mile,then nail it,go back to normal driving,take it up to higher speed,55/60 drive a mile nail it drive normal,then see if that helps.It might take some miles 4 tanny 2 relearn your driving habitsSo I finally got around to disconnecting my car battery and resetting the cars parameters. Once plugged in, I took it out for a "lively" drive on the highway. I used Autostick to give her some healthy WOT runs, but at one point I left it in D @ 65MPH and just mashed it.
Well, the ultimate result was not very nice. It THUNKED it's way down to 3rd gear. I then decided to use Autostick again and left it in 4th and decided to downshift and once again, THUNK.
I tried another WOT run from D and same result, a rough THUNK down to 3rd. At another instance I used Autostick to get into 3rd and gave it some light to mild mashes of the gas, and it was quite rough.
Is there something I should look into in specific to fix this? Or was the battery pull the possible culprit, and the car just has to learn it's way around? I just bought the car a week ago, but this is the first time I've opened her up like that.
