All of a sudden my 03 TL has started having a shifting problem. D5 light blinking, check engine light came on as well as TCS light. Accelerating from a stop it slips until I let off the gas then it grabs 2nd gear. Same slipping until letting off the gas then grabs 3rd, ect... Engine revs before all shifting then runs fine when in gear. When key is re-cycled D5 blinking and TCS lights are gone. Cleared codes and check engine light gone as well. Runs and shifts fine when engine is cold. Warmed up problem returns. The codes were P0705 and P0750 I think. I checked the A & B solenoids for operation. With 12V applied solenoids click and the valves operate. What do you think?
