Answer 1

Could be a bad harness ground. Try cleaning all the harness ground you can access.

Also, did you replaced the radiator? the radiator is possible the cause of the problem. Coolant leaks into the transmission cooler, which is inside the radiator, The coolant damage the internal electronic components of the transmission.
