I was hoping someone may have an idea of what is going on in my Transmission of my 1999 ML320.

My ML320 was experiencing jerks between gear changes and throwing a 110 (speed sensors implausible readings). I changed the connector, replaced conductor plate. New MB ATF and filled to correct level.

Now the car runs fine and no more jerks between gear changes. However as soon as engine gets to normal operating temperature (80 to 90 degrees Celsius) the car goes into limp mode. It now throws a code 109 (intermittent fault on sensor 3). As long as the car is warm it keeps on going back into limp mode. When it is cold it drives fine again until it reaches normal operating temperature and then it goes back into limp mode again.

Any idea why it is doing this when it gets to normal operating temperatures?

I appreciate any help that you can give.
