mine started doing this today in the rain i hit a repaving bump at 70 and it started flashing and droped out of overdrive,pulled over shut off and restarted no problems for maybe 3 miles started flashing again but no drop out of od however it seems like the torque converter is not locking up at cruise and taking off it shifts like a shift kit through the gears.does it every time i shut off and restart..good for 3 to 5 miles then starts doing again.i figured the bump loosened something alowing moisture in so an way home i stopped an got some wd40 an got under it i only saw one plug though on the driver side of the transmission pulled it out sprayed it good plugged it back in but nothing changed are there more plugs im missing?any ideas?
