I have a 1996 e320. The problem I'm having is that it runs high rpms. It shifts smooth all the way to 4th. I can be going 40 mile an hour with cruise control on and it will be at like 2000 rpms. If I give it any faster it goes up and up. I'm scared to go above 40. Any diagnoses or theory's...thanks

It would appear the torque convertor is not locking up.

check for transmission trouble codes.....any codes. we could all help with
keyboard speculation but you may as well take advantage of the onboard
sensors to give you a clue first. so in order to do that, you need to access
a code reader.

Would an autozone reader work? And how do I access the onboard sensors.

It depends on which one they use. There are specific codes which, if present, will be useful; however, basic OBD-II readers will just return a generic transmission code rather than the specific ones.

If you have an AAMCO near you they say they will check codes for free, and their system will return the specific codes.

The onboard sensor reference includes the specific codes, too.

Good luck.

Don't think Autozone will have specific reader for MB transmission.
When I check around, even AAMCO did not have it and the only independent shop in East Bay (of San Francisco) wanted $140 for reading the codes.,
Did anybody mention checking the fluid level?

The good thing is that he has the four-speed transmission, so there's less concern about the electronics.

Ladies and Gents, many of you may have had the opportunity to benefit from the above gentleman's vast store of Mercedes-Benz knowledge. I chose this thread to post this notice in because the thread title is so suited his call to arms on this forum. As he himself might say, when he avoided beer, he would go to the ends of the earth to help another member with their mechanical issues regardless of model or age.

I know how most of you avoid Off Topic (BWOT) assiduously but there's a thread up there that, if he had ANY impact on your M-B life, might be something that you want to drop in and visit and share a story or two if the spirit so moves.

Cancer

He will be missed.
