While trying to be brief I left out some info-I did have the flashing arrow.I cleared codes and drove car for about 5 miles.This time when I come to a stop the engine rpmsflux 200-300.and when I shift to rev the car stalled.This occured 3 or 4 times then seemed to clear up. I retrieved no codes other than 111 from A1 plug.
How do I troubleshoot the speed sensor? the fluid is pretty brown so I'm headed out now to buy fluid.Judging by other posts a fluid change is a good place to start.Thanks for the help so far.
