2008 Saturn Vue AWD transmission problem.?

A friend has a 2008 Saturn Vue AWD.

It won't go into reverse at all, and, while it will drive forward, it won't shift right.

He had a guy that's supposedly a professional tech, but also has a shop in his home garage scan the vehicle. The guy told him that the code(s) were for a "turbine input sensor" and that the vehicle is in "limp home mode".

I don't have the equipment, or, the desire to work on anything newer than about 1995 (a.k.a. O.B.D. 2) but I'm curious because the other guy didn't know where the sensor is located and didn't even bother to write down the codes that he pulled.

I know what limp home mode is since even O.B.D. 1 vehicles do that, but, my questions are...Is there even a part called a turbine input sensor? And, if so, would it cause the problems that my friend is having?

    yes it has that sensor. It's inside the transmission. And yes, it would cause limp in. It measure the speed coming in from the torque converter. PCM known the engine RPM and knows what input speed it expects to see based on that engine RPM. If it doesn't see that, limp in mode
