1999 E430
160,000 miles

When it is cold 32 degrees or less, car does not shift from first gear when shifter is in overdrive position. I can "nurse" it through the gears one step at a time from 1-3. Once warmed up car shifts fine and no problem in summer.

Sometimes during the above warmup period I will come to a stop, forget to down shift manual and the car barely moves out of first.

Fluid level is fine....could this be a simple adjustment needed?

please respond direct to

There's nothing to adjust. The entire transmission is controlled electronically. This problem seems kinda wierd. It's definately unusual. Does the Winter/Summer mode affect anything? Are you sure the fluid level is fine, especially when your car doesn't have a trans dipstick?

I know , this sounded weird to me too..but thought it might be a German thing.

My local shop did use his stick to check level and DID teach me about the W/S switch. it is on 'S" all the time. I did have it on 'W".

When he taught me about the switch I thought that was "IT".

Thanks so much for taking the time to respond. I really enjoy this car and would like to stay on the road with it!

Any other ideas?

By the way...I had the diff replaced and drive shaft done but this situation has been on going and first presented itself last winter. it seems to be worst this winter.

cold transmission 99E430

I have a 99 E430 myself and it does the same thing. My partner has a 98 that also has the same symptom. I have taken my car to the dealer and to a local reputable Benz specialist and they both told me the same thing.

Read your handbook first. This vehicle will not operate correctly until the operating temperature is up to approx. 85 degrees F.

I let mine warm up and she runs like a charm. It's a bit of a time inconveinence but it runs just fine when it gets hot. The explanation I got was that the tranny is heated up by the engine and theres some type of soleniod that triggers at 85 degrees indicating to the tranny that the optimal temp has been achieved.
