Hi All,

I bought a Chrysler Crossfire, actually the only thing that is on the car that is Chrysler is just the badge, every thing else is made by Mercedes, so here is the question.

The car was in an accident, front end damage, the person who repaired it, had to remove the engine and tranny to repair the frame damage, the car wasn't drivable after the accident due to the severe damage.
After putting every thing together, the car is stuck in first gear (automatic transmission) and refuses to shift.

The engine light is on, so I plugged in the ObdII tester and here are the codes which I got.

P0715 Input/Turbine Speed Sensor Circuit Malfunction
P0763 Shift Solenoid C Electrical

I took the car to Chrysler, after aweek sitting there and 570 dollars, they couldn't figure out the problem, so I took it onto myself to see if I can find the problem. They told me exactly what I already know which is the two codes that I already pulled from the OBDII tester.

If some one can explain in details what the above codes exactly mean and direct me in the correct direction on trouble shooting, I would be ever greatful.

The engine is a 3.2L( it is not supercharged), automatic transmission. Both the engine, transmission and all the component on the car are stamped by Mercedes, even the ignition Key.

I have a decent knowledge of mechnics and I have a good knowledge in electronics.

Here is what I did.

I removed the tranny oil pan, removed the selonid body and ohmed out all seloniod, every thing ohmed out good.

There are two sensors which they are magnits, I don't have a good understanding on how they function, so if some can explain in details, how they work and HOW TO TEST THEM, that would be great.

My apologizes for the lengthy message, but I am getting frustrates with this problem, it has already costed me quite a bit of money.

Thank you,

Rafi
