Hello, about 2 1/2 years ago I changed the transmission band and solenoid A, it solved my problem. Now I have the same problem, OD light flashing get car up to 30/33 mph won't go up to next gear. I dropped the pan replaced both solenoid A and B new filter/fluid problem still exist. Does the band need to be replaced again or could it be something else, like the speed sensor. Appreciate any help/suggestions, thank you.
