Monte Carlo not shifting

I have a 2001 Monte Carlo SS limited edition . I have no gears except first and reverse. it will not go into 2nd or any other. a code reader said something about the shifting parameters? I wanted to know if it would be the shifting solenoid. or something I could fix myself

Try and post the exact codes.

I do not have the exact codes. this is all the information I have. it is not my car yet I am trying to buy it or thinking about buying it.

Well the shifting is controlled by the pcm, all electronic, no way to pin this down, without the proper info.

okay thanks I'll try to get the code

Unless you can get this DIRT CHEAP, I'd reconsider buying a car with shifting issues.

I'm going to bet the forward band is broke. That requires a full trans tear down to even fix it. With the forward band broke it will take off in 1st and you can manually shift from there, but it wont last long.

okay thanks for the info
