I have a 2007 ML350 with 106K Mi and my transmission has gone into limp mode but in a high gear 3 times in 2 weeks... I've scanned the computer with a friend's scanner and the codes for input speed sensor A & B have come up... I called the dealer and they told me it could be anywhere from 1k to 2k+ to fix my problem depending what they diagnose... Has anyone delt with this problem and if so what fixed it? Thanks!

 

Did you recently buy this truck?

From the codes posted, P2004 is a monumental job in that the top of the eng. must be dismantled.

Since you already have the codes documented, I suggest you clear all the codes in the ECM and Trans Module, take it for a ride and rear the codes again as soon as the problem occurs.

 

No I'm the original owner... After reading those codes... I reset them but haven't read them again....
My main focus is the transmission and what I would need to fix it

 

I understand what your focus is but we will not know until the codes are read again.

If code P2004 return, this is what you are up against.

 

TORQUE wrench?? Its spelled TORX! <sheesh>

And I looked at the length of the video... 21 minutes? Not on THIS planet! Then I saw how they speed up the video between explanations. LOL!

 

Oh ok I see! I've watched that video before and I will probably deal with that later... I've been driving with the intake code for 5-6 months and I've been alright.... I'll have to get the codes checked again soon

 

I'm having the same issues did you get your issue resolved. My problem started with a bad ABS sensor. Replace but now I'm stuck in limp mode I believe. It won't shift out of 1st gear
