I swapped out the engine for a new engine out of a totaled car. Everything was the same, using the original transmission and ECU. Car idled great when I took it for the first test drive and after about 600 feet the transmission disabled itself. It didn't make any noises, or anything. It was working great then stopped. I've cleaned the main plug several times with electric cleaner spray and still disabled.

Hi,

I need a little more info. What model is the vehicle? Also, have you scanned the can-bus to see if there are diagnostic trouble codes related?

If you haven't, I recommend doing it. CAN stands for controller area network. Basically, all the computers/modules are tied together via a few wires and communicate with each other. This type of scan will retrieve codes regardless of the module storing them. Here is a link explaining how it's done.

Let me know if you find codes and what they are, and I really need the model.

Take care and I hope you have a great 4th of July.
