On long trips (over 100 miles or so) the trans intermitently goes into limp mode (stuck in 2nd gear). When it does this, I have to stop,shut-off the ignition,start again, and then it goes through the gears. At the next stop light the process starts all over again. This does not happen on short trips around town. My transmission guy says that my transmission control module does not have cooling fins and he has never seen a plymouth module without cooling fins. He thinks that on long trips heat build-up is breaking down some components inside the module. He road-tested the trans and it was working good. The only thing that the code readout says is the trans is going into limp mode. He'll install a new module with cooling fins for $300. Has anyone else had this problem? I'd rather not get into the "Let's try this and see what happens routine."Thanks in advance,Ron
