Upon start up, I receive the 730D code, which seems related to the transmission. The car shifts smoothly and their are no noticeable issues and I even took it on a road trip without incident. Any ideas on what might be the culprit for this code?
Do you

Hi,

The 730D code means the maintenance on the vehicle is 730 days overdue. Perform the recommended services and reset the computer to clear the service warning. Let me know if you need anything else.

Is there a reason that it stays on 730 rather than add days as time passes? When you google 730d code for a Mercedes ml350 it talks about transmission gear ratio? Do you have any thoughts on that? Thanks

I saw that as well, but I also found this:

http://www.justanswer.com/mercedes/6ojef-mercedes-benz-ml350-05-ml350-says-730d-wrenches.html

Which describes the reset procedure for the service, have you tried resetting it?

Follow these instructions and get back to me please,

Best, Ken

I have a 2003 ML350 with over 248,000 miles on it. Lately but not often while driving the transmission would slip out of fear but would shortly slip back into gear. What are your thoughts as I also have the code 730d

Hello,

It sounds like the fluid level is low I would check that first here is a guide to help you get the job done.

The code 730d? is this an euro car?

Check out the diagrams (Below)

Thank you so much. I had the transmission serviced and that corrected the slipping out of gear.
