i had a lot of corrosion in my ecm

so we change it for two used ecm
car refuse to start or the transmission did not respond

any idea what the problem is?

reprogram the ecm or the transmission?

You can't just throw in another cars ecu, they are vin coded to the tranny tcu. You need to have the used ecu reprogrammed with your cars vin. I doubt the dealer will do this, you might need a tuner or really good shop.

I just bought this car 2 months ago
Many salt on our roads in winter
Tuner told me few pins as in bad shape
Connectors seems to be ok
