lugs when upshift from 2nd

I think most all autos do, it stays in OD if you tap the brake pedal or tip/tip out of the throttle lightly. If you drove at highway speed, say 70 mph and while holding your right foot steady on the gas pedal tapped the brake with your left lightly the rpm will flare slightly, that's the TCC unlocking for a moment then locking again. This is why I think his tranny is shifting into OD not simply locking. Hard to diagnose a problem at distance though...

go figure. I stuck the + of my mutimeter into the orange yellow coming out of cpu and grounded the -. when engine off its full resistance. started engine,full resistance. ran down the road and the son of a bi..h shifted smoothly all through od, which dropped the mutimeter resitance level at just the right time. Now the next question is, I manually shifted from OD to D and the tranny felt like it downshifted, but the ohmmeter didnt change when I did the manual shift. gonna go back out and do another test drive without the multimeter diluting the ground and see if it shifts right or its back to ...

ran it after pulling multimeter and everything works fine. even checked tcc by tapping brakes at 55 in OD and saw a minor jump in rpm. Guess it decided it didnt want me working on it or wants to wait til its cold out or something

Crazy **** yo...

Way too many beers tonight.

Glad it's behaving. Maybe it's like a horse and needs a good crack in the ribs once in a while.
