Hi, last week out of the blue my car started to become sluggish and had no power. I was told it is stuck in 2nd gear and wont upshift or downshift. The trouble codes are po600 and po705. What is the problem and what needs to be fixed?

They indicate computer and PRNDL switch problems from the transmission computer(TCM). OK Joe

No. Try to see if the plug came off the PRNDL switch, check the engine fuses under the hood next, replace the PRNDL(prindle) switch next and last is replace the TCM. It is the way it is done. Using a powertrain diagnostic procedure book.
With 80,000 miles it is more likely a wiring, fuse, or switch than the transmission control module(TCM). Ok
The switch is right on the trans, in front so it may be hit by something.
Good luck, and check back if you need further help. Joe

Thanks joe, I will definitely have someone check out the things you mentioned. Also, I read your message, but my problem is the money so I cant afford to take my car to Chrysler to have them repair it. Im just really praying that its just the plug like you said or something minor.I need my car, but dont have the money to get it fixed at the moment. Sad face

I certainly understand. A small problem on these units can wipe the whole trans out so that is why 2nd gear. So you can limp in. And not ruin the whole transmission. That's ok as long as you are offering support for your products service. Very few outside shops get that support and now neither do Chrysler service people. It can only get better. See ya
