i have been reading some postings with somewhat similar issues with interest.but my problem seems somewhat different so thought i would start a new thread. i have a 2005 e320 cdi and when the trans temp is cold and the ambient is below 50F, i have harsh shifting in all gears and it seems to want to upshift way too soon. this results in the car lurching down the road and sometimes the engine will hunt up and down about 100 rpms. especially in 3rd gear. trans fluid and filter changed regularly at 25-30,000mi and most recent was about 4000 mi ago. using pentosin atf-1 in it. have about 300,000mi on the vehicle. no codes. once the temp is up the trans operates normally with an occasional brief down shift when at highway speed. this has only happened a few times. i have also experienced the lurching problem even when the electric engine heater has been on and engine at 80c but trans is not up to temp. i have read on some of the postings about a temperature sensor inside the trans, where is that located? anyone have any new ideas on this issue?
