MY01 E430 @ ~210,400 Miles
A couple of days ago as I came to a stop sign, I noticed that there was no clear downshift. I usually touch shift to slow down - that was not working either. The transmission was stuck in some gear - the display showed 4
but I know I wasn't in 4th when I started to move because of the higher than expected revs. It was not slipping - it just would not upshift. Thinking this was electronic related, I stopped the car, waited for a while and restarted. Everything started working just fine. Later in the day, shifting into R
came with a thick "thud" I'd never felt on this car. In D
, it "thuded" again into the next gear as I started to move - this is like near crawl speed. I drove to my local mechanic (it drove fine) and had the tranny oil changed (I have already done it twice on this car, but I was just hoping...). All was fine as I drove to DC yesterday. At one point on my way back, I put my foot down hard on throttle to execute a pass. I was expecting kickdown but nothing happened. The tranny was stuck again in some gear (display showed D
) but it couldn't have been due to higher than expected revs at speed. I stopped, turned off A/C and after a while, the 1.5 Hrs drive home was uneventful. I can't recreate the situation because I don't know what causes it. I turned off the A/C just because in my mind the tranny could be overheating and the A/C would not be helping - I just wanted to get home to deal with it later. Help folks. Thanks.
