i'm am noticing a big stumble in my '04 MC CVT...i goin to the dealer in a few days, what do i ask for in regards to the software updrage? and how do they do it?

 

Call your service advisor and make an appointment to have your MC checked. Tell them what is up.
The ECU software update is version .36. Most of the comments about how it is helping deal with MCS with stumble not MC.

Version 36 should help the stumble problem on both MC and MCS, at least that is what my service advisor told me. I'm getting my MC upgraded this coming Wednesday along with my 10K oil change.

Wish me luck!
