Hi all, Trans in my 350SDL with 289K started acting funny this winter……
If it’s cold out, < 20F, If i drive off without a 5-10 minute warmup, the trans goes back and forth on the 3-4 shift. If I drop it down into 3 for a mile or two and then put it back into D, it’s shifts OK. Also, If have to stop in that 1’st mile or so when cold, the trans slips. (3K revs and the car barely moves) Once it warms up, it shifts fine….hard acceleration from stop gives smooth shifts; kick down works fine, too. A few days ago, it was close to 60 out, and dead cold, it shifted fine. Don’t know if it’s a B2 modulator (?), a vacuum issue or the trans is just on it’s way out. Trans fluid and filter changed religiously every 45K. A Benz mechanic told me that if it shifts fine when hot, it’s something external and not the trans. Any suggestions? Other than the usual “wait for the engine to self-destruct? <g> Thanks Angelo Giaimo 1990 350SDL 289K 2011 ML350BT 40K 2001 BMW 530i _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
