Limp Mode P0715 code C320

I have a 2004 C320 wagon. I was getting the p0715 and p0730 error codes so i changed the contactor plate above the valve body and the connector.

now Im just getting the P0715 code everytime I drive it and its stuck in Limp mode (stays in 2nd or 3nd gear, clunks into gear hard)

when i hit the "C" or "S" on the shifter it doesnt do anything. Just stays in "C" and when i put it in Drive and try to shift down it doesnt do anything. just stays in "D"

I checked the fuse for the trans computer and its fine. I looked at the connector harness that plugs into the trans and that appears to be ok.

I searched this forum and I found alot of info but nothing is working. Im about to have it towed to a independant MB shop

any help would be appreciated.

thank you
Rye

yes. I have a code reader (not a scanner) and I have cleared the code many times and it comes back

P0715 = Input/Turbine Speed Sensor Circuit Malfunction.

This is not an easy one to answer. Sometimes all that is required in this situation is readaption with a Star.

Let's see what others have to say.

P0175 should be the trans speed sensor. It's located in the conductor plate.

Glyn mentioned a good point. Got me thinking..when you erase code does it get erased and comes back? Or it doesn't get erased at all?

I can erase the code, the "check engine" lights goes out but when I start it its still in limp mode and the check engine light comes back on.

I have replaced the eletronic plate on top of the valve body.

I'm just throwing this out here - is it possible a leak from the known faulty pilot bushing is causing false errors?
