Replacing "Power Trans Module" programming.

Australian right drive ZJ Grand Cherokee has just had the "Power Trans Module"(PTM) (that's what the mechanics are calling it??) replaced and have been told it needs reprogramming. Jeepy disgraced herself by stopping in the middle of town!! Wouldn't start again. Diagnosed by auto electrician without the aid of a scanner to be dead PTM PTM replaced and now Jeepy is running again but remains in first gear (auto) I'm told this is Limp Home Mode and the PTM needs reprogramming. We don't have access to a scan tool to interogate/program this vintage. Can any body help with ideas please.

You will have to take it to a dealer to have it reprogrammed unless you can get access to a drb 3 scan tool.
I dont know if someone on this knows if it can be done with a laptop computer and some special software.

Thanks for the info. I have also queried our local (180mls away!) Jeep dealer and he said "Bring it in!" At least I now know which scan tool is required.
