E430 different transmission problem
I have a 1999 E430 with 68,000 miles. I back it out of the garage and drive a block to a stop sign. The transmission usually upshifts at least one gear before I get to the stop sign. When I start to go forward after the stop it will have a jerk as if it is taking up slack in the u-joints or rearend. I think the transmission is not engaging until the motor revs up just a little and when it engages that causes the jerk. It is like it hesitates before the transmission engages It always does it in the winter when it is somewhere below 50 degrees. It didn't do it in the summer until this last summer and then it was very slight.
Anyway, after that I drive it to a second stop sign which is 4 or 5 blocks away and it doesn't do it again. The transmission acts perfect after that.
I took it to the Mercedes dealer when it was still under warranty and of course it was warmed up and when they drove it they couldn't find anything. They checked the transmission oil and even smelled it saying it was ok. they did add just a little oil, the service guy said he liked it when it was completely to the very top.
After it was out of warranty I took it to an independent where I knew the son of the service manager. They checked it for codes and found none except for interruption which probably came from when I changed the battery.
I asked about changing the transmission oil and filter and he said they didn't recommend doing that. He said if there is a problem it can make it worse by cleaning up all of the parts in there with new fluid. They also added just a small amount of fluid saying they found the transmission works best when a little over the full mark. It didn't take care of the problem. I have just kept on driving it being careful to not give it too much gas the first time pulling away from the stop sign.
I would like to think I have some mechanical ability and with the help of this site have replaced both rear window regulators and the MAF.
Any suggestion would be appreciated.
