if my transmission control module goes out do i need to replace the transmission

What is your question?

I have a 2002 acura tl. with about 165,000 miles. I was told that I need to replace my transmission by the dealership. due to the car not shifting into 3/4/5/ gears . it would just stay into Limp Mode. I have connected a OBD scan tool to the car. The reply from the SCAN TOOL was it would not connect. what would be the cause of it. I replaced my output sensor as instructed by the dealership. would I need to replace my transmission because the dealership said so. they stated with there testing that my transmission control module is faulty. could I just replace that part with a new pre-programmed unit. what should be done about this issue? thanks for your time

What makes this problem better or worse?

the same issue I'm changing solenoids at the moment

How long has your 2002 Acura TL had this problem?
