The Powertrain Control Module (PCM) can be found beneath the dashboard, positioned under the front lower panel behind the center console. A transmission control module (TCM) is an electronic device that gathers and interprets data to manage the gear shifting in your transmission. If you notice any signs indicating a faulty TCM, such as trouble accelerating or slipping gears, it's dangerous to drive your car, even if it's somewhat functional. It's crucial to contact a local transmission expert right away for an assessment. Replacing a transmission control module can typically cost between $500 and $900, with parts averaging $450 to $700, and labor around $50 to $200.
In the 2002 Honda Accord, you can find the transmission control module inside the transmission towards the back, under the end cover.
