Another "limp" mode problem - P0700
My 2002 intrepid has the same problem many other peoples do; the transmission jumps and I'm stuck in 2nd gear until I restart the car. I get the P0700 code which is a general transmission control system failure. I've replaced both input and output sensors already. is it possible that I just need to flash the tcm at the dealer? The car sat for a year or so without the battery connected. The dealer said it would be 150 just to look at it so I wanted to try to fix it myself first. I just bought a tcm from a junkyard. What shoul I look at next? Replacing the tcm or flashing the one that was in the car? Or should I try something else like a solenoid pack?
