Hello everyone I have a 1997 e320 w210 with a CEL on code (P0730)INCORRECT GEAR RATIO and is now in Limp mode drives in 2nd i believe and doesnt shift.Clunks when i put in reverse and drive..The cars mileage is 100k and I recently over flowed the tranny with atf because the first shop there was so much it was leaking so I then replaced the conductor plate,ATF Plug,gasket and filter at a shop that's now telling me it needs a new tranny.What they failed to tell me that my transmission control module was soaked in atf that I found when researching and decided to check.I removed the tcm and cleaned it with MAF as well as the connectors.Now waiting to insert everything,clear the code from the tcm and give it a try.Please anyone know why I'm getting this code and what else I can do to fix this car.Thank you all so much for your help

Welcome to BW johndoe,

As the Thread Title says, No Car Repair issues in the New Members Welcome Forum.

The forum index is organized / grouped according to chassis designation, usually a letter followed by 3 digits / numbers, and sections cover all engine / versions the chassis came with.

To find the forum section = chassis for your car, please click FIND YOUR FORUM SECTION
And Complete your Profile by adding the year and model of your car, so it will show next to every future post under your avatar.
Members are not likely to search for the one post the model of the car is mentioned.

The forum section archives have a wealth of DIY / technical information.
When researching an issue / posting, you can also Search the forum archives of your chassis section via the 'Search Community' box on top..

The stickies on top of the 'Welcome' section will help to navigate the site.

Moving this to the w210.
