It shifts normally in the manual position, there are only problems in automatic position. Also, shifts lights and DSC lights are always on in "A" and "S" position.

No radio, I think it is a fuse

error code is CC ID31 came on.

I have a manual transmission. Sometimes on 1-2 and 2-3 shifts I get a "tick" or a slight grind. It happens more when the weather is cold. I'm worried that my synchros are going bad. I'm thinking about getting rid of the car before this happnes because of the expense of a new tranny.

It started yesterday, when all of the sudden my SMG when off gear, the gear number started to blink and the transmission yellow light turned on. After this i turn the engine off and back on and wouldnt go into gear, then with the engine off i put it in gear and it worked, however when i push the car to 4000 rpm or more it doesnt go into the next gear, right now is skipping 3rd gear. Any ideas are welcome

My mechanic told me that the fuel pump cannot be sold without some sort of sensor, but that there are two of these on each side of the tank in order to maintain proper fuel readings on the dash board.

He explained that the other sensor MUST be replaced as part of the job, in order to ensure I get accurate fuel readings. This added $400 to the cost of the job, bringing the total to $1000.

Does this sound right to you?
