Power train Control Module, 2001 Accord

Your image is false/incorrect for a 2001 Accord.

The Engine Control Module or Powertrain Control Module is located under the center of the dash.

isnt that the main computer? im trying to find the one for the transmission computer.

On a 2001, it doesn't have a separate transmission computer. For automatics, it is a combined unit and called a powertrain control module (PCM).

What issues does the car have? On 6th generation Accord (98-02), the PCM generally is not the source of transmission related issues. Instead the transmission can have issues.

it is over revving, and the other day the d4 started to flash. the transmission was recently replaced with a used one.

Hmmm, sounds like it may be a bad replacement transmission.

see thats the thing this is the 3rd transmission. every single one of them over rev when changing gears.
