4l80e problems
I have been reading some forums before i post and i have a 4l80e that don't shift into O.D. and when its cold it doesn't want to shift from 2 to 3 very good(I shift it manually to keep from tearing anything up). when the trans is warm it shift from 1,2,3 no problem. but no O.D. I checked codes and i am getting p0711 and u3900. I replaced the filter and fluid 500 miles ago. I read on here about testing the TCC by checking resistance from pin E to S. I checked it and it reads 0. When i took the connector apart there was trans fluid on the connectors pins (is this normal?).PLEASE HELP
