New member with a tranny problem- help!

[hudsonhornet7x]

I just found out about this site and as I am a new pt owner I thought I would post with a big problem. I have a 2002 pt limited and the tranny will not shift. I put my scan tool on it and the code comes up as p0700 which is a dtc with the tranny controller. It is here where I am at a loss. How do I find out what part of the tranny is bad?

I believe from the research I have done that the tranny is in a " limp home" mode that leaves the car in 2nd gear. After that bit of info, I am stuck in the dark. Help!!

I think Its saying the controller is bad.

That is the generic code which will come up.

The dealer has more specific means of getting the actual codes.

How many miles and any service history?

You could throw some speed sensors and or solenoid pack at it but I would have the dealer take a look.

The car has 117,000 miles and I have no service history of the vehicle. ( bought it cheap at an auction. Is there a special scan tool needed to further diagnose the problem? I take it that is what the dealership will use?

Yes, the dealer has tools called DRB and StarScan. A 2002 will use the DRB and it will communicate with the car systems to determine the exact fault and repair needed. You cannot do that with a standard universal scanner.

If you have not already tried it, I'd pull the neg battery cable and stand on the brake pedal for 5 min or so to discharge all residual? memory.
Then reconnect to see if the code reappears.
I threw this code a few years ago at the track. Dried the tires off after going through the water box and BAM P0700 green light came on and i limped to the first cutoff
Luckily, I haven't seen that same code or been back to the track since

Okay, I have an update. I tried a better scanner tonight from a friend and pulled an additional code. P0605 Internal control rom module malfunction.

I have tried several searches on this website and others and am getting conflicting info from them. Any suggestions what to do from here?

[heifetz17]

Both P0700 and P0605 are TCM faults. More importantly P0605 is an internal fault within the TCM, for which Chrysler recommends replacing the TCM.
