Hi Im David, Ok, the light is flashing because there is a fault in the system, what needs to be done is to find out what corresponding code there is, the easiest way is to get a scanner that can read the transmission codes. until you can get the transmission codes there is nothing that can be done.

Could computer controller burns the transmission?
Expert:  david craig replied 19 days ago.

no

Expert:  david craig replied 19 days ago.

you need to get the codes that are in the transmission control module. there isnt any sense of asking anything else. i dont guess.

Transmission was replaced 4 months ago, now they want to replace computer controller. Does this sound right?
Expert:  Daniel Wilson replied 19 days ago.

Hi my name is***** actual AT temp needs to be confirmed if it is an actual temp problem or a faulty temp sensor or harness issue causing the fault and you will need to have a scan tool plugged in to get the fault codes logged which tells us what component or part of the circuit the fault is in. Make sure the oil cooler was flushed or replaced or it could contaminate the new transmission if they did not. Let me know

I don't know how to troubleshooting myself. Four month ago dealer replaced transmission and harness cable. Now Dealer says computer controller is bad. In order to fix AT OIL Temp blinking, they said computer controller needs to be replaced, otherwise will burn the replaced transmission. Does this sounds right?

thanks for the update. It is possible yes if the software or controller has an issue it could over time caus a failure. This is the last resort. I would hope they went through all the testing of the wiring and sensors to narrow it down to the controller and not a mechanical problem from not flushing the circuit and oil cooler when they replaced the transmission. I would look into that as a controller will not correct an actual overheat issue. If there is not true overheat issue then the controller can give a false message is there is a problem with it or the wiring or sensor. Let me know
