I just did an automatic to automatic swap car
was driving fine but now doesn’t read what gear it’s in and won’t start SOMEONE PLEASE HELP

 

did you look up that error code? And you need to provide additional information about your car. what model year is it?

 

code u1000 and a 2007 hr

 

okay, I guess you're not going to look it up yourself. you can Google this stuff you know.

unfortunately, that doesn't seem to be a simple error code, it indicates a faulty ECU or perhaps some bad wiring or corrosion. there is a secondary error code that goes with it. that should help narrow down the problem. If you need a new ECU, they're about $300. there's a company that can clone one for you with your car VIN.. hopefully it will be a simpler problem.
