hello guys, how can i know if my transmission has the correct or wrong software number? Thanks.

 

 

It's unfortunate seeing all these rear subframes with severe corrosion. However, I highly doubt the damage was done over a course of a year, since either an A Service or B Service would have you inspect the underside of the vehicle for damage. Unless you only do an annual oil change and nothing else. The key to making these cars last I to do the all required maintenance steps in found in your service booklet.

 

Take your W204 to a MB dealership for your next A service. Ask them to perform a FREE TCU (and possibly ECU and Engineering Mode) software update with their STAR service computer. Makes an enormous differences. Factory policy is that software updates are included with any service, don't let the dealer tell you otherwise!

Perform a gas pedal reset occasionally. This will provide the correct information to the TCU for more responsive downshifts.

 

I second that. After having the dealer update the TCU and ECU software, the car shifted and drove smoother. The TCU software also got rid of the transmission jerk that I was getting when downshifting sometimes from 3 to 2 and 2 to 1. It was a known issue and the solution was a software update. Highly recommended especially since it's free.

 

 

Here’s a 1985 GE280, converted to US specs and absolutely full of rust! For Sale!!!

 

Ok......it is kind of interesting, I guess, but why did you post it in a thread about transmission software?

 

Because the guy above him, Alexc4matic, posted about rust issues as well. Ughhh!

 

Bought the car new in 2010. Always garaged. No accidents and well maintained. 120,100 miles. Felt an odd movement when breaking and a squeaking noise when in motion. Thought it might be my brakes or wheel bearings, but was floored to find when I took it to my local shop. The Subframe is rusted out and separated completely. WTF? How can this happen? I can’t believe Mercedes or the NTSB has no recall on this dangerous situation. Got a quote from the dealership who I bought it from, Loeber Motors north of Chicago, of $7122 + tax, yah that’s right, couldn’t even round down to $7120 or add tax. Unbelievable! Now trying to figure out what to do with this. I can’t image accidents have not been caused by this derelict use of materials in the subframe. Mercedes must be keeping it hush and paying off any suits not to have a major recall.
