It's getting colder here in Michigan and each morning my wife drives to work in the 92 Benz. She has been telling me me about this problem. I drove her to work this morning. When the car is cold. it will not shift into second until the engine speed gets up to 2500 or so and the same from second to third. After five minutes, it is shifting smooth again. I have checked the transmission fluid level (hot), and find that it is about one inch over the full line, (splashing?), I don't know. I have owned this vehicle for two and a half years now and have not had the transmission fluid or the filter(s) changed. I have put about 48000 on it in that period. The fluid itself appears to be clean and pink. I had an experience with hard shifting about four months ago and my machanic blew some lines out and it went back to normal at that point. Any help or suggestions?

Third winter with my 92 diesel : when cold, it shifts at higher rpm. On earlier models with a vacuum amplifier, one could disable the temperature sensing device that cause the high rpm cold shifting (check reply by jcyuhn 11-29-2001 on late shifts). 92 models don't have a vacuum amplifier : I don't know what is causing the the high rpm.

My 123's are affected by cold as well. It seems like any little problem is exagerrated by cold.

I have one that slips in the 2-3 shift when cold. Sometimes I find that it has actually gone into 4th and skipped 3rd. After a few minutes when everything is warm, it shifts at the right point crisply and smoothly.
