Hello everyone, I am having an issue with my transmission. It seems to runs fine until the transmission warms up, all the gears work, then loses all the drive power like it is in neutral, and makes a whining sound.

I then turn off the car, wait some time for it to cool down, restart it, and it drives fine again, goes through all the gears without whining, then a few minutes later after the transmission gets warm, it has no drive again with the whining noise returning.

I checked the fluid with an official MB dipstick, and the fluid level was fine, but it seemed burnt and cooked. The car has 175,000 miles on it, and I last did the transmission flush/filter changed at 130,000 miles with oem filter and the correct fluid.

Does anyone think this is due to the burnt fluid, like it doesn't have the proper viscosity making it too thin when it's warm making it slip and not engage? Think just a flush/new filter would remedy this?

Any help would be appreciated.

 

Hi! I have the same problem, I would like to know if you managed to fix it, and how did you do it.

 

Never fixed, car is parked, rotting away! Let me know if you come up with a fix! LOL

 

Hi! So, I managed to fix the problem, first I checked all the solanoids and then I switched out the conductor plate, and it is working just fine

 

I had the same problem.
I had purchased a 2003 e500 with 72,000 miles on it.
It would drive for a few hundred feet perfectly then rev up and whine. It turned out to be very dirty oil in the tranny and a plugged filter. I changed the filter and flush the transmission several times the car has now 95,000 flawless miles on it.
