Trany problems - limp mode
 

Hello yall,

about 3-4 weeks i had "electrical connector at valve body conductor plate leaking" issue on my 2003 c320. I had this fixed, and ever since they fixed this, the car would (every now and then) go into limp mode (high revs, but barelly moving).

Today i got the CEL on, and the codes are P0715 (input/turbine speed sensor circuit malfunction) and P0730 (incorect gear ratio).

My question is what to do about these codes, i have done a lot of work on my audi, but never worked on a benz, is this a DIY type of thing?

Also, do these codes have anything to do with the conductor plate leaking issue above ?

I would greatlly appreciate any help.

Thank you
