I have a 1991 420SEL 133000 miles, One month before when shift to (R) the transmission delay about 20 sec to engaged. I had the trans fluid & filter change, Now...When the engine cools down the problem does not happen, after 30 mins of driving REVERSE does not work(just no reverse)drive is still ok, after turn off the engine cools down about 2hrs the the reverse comes back but it still engage slowly.
Does someone know which part has problem.
Thanks,
