1) Disconnect the battery 2) Under the carpet on the passenger side you will see a metal "box" that is held down by 4 x 10mm nuts. Remove these nuts to loosen the box. You will need to reach under the silver plate to disconnect 5 connectors - 3 on the left side and 2 under the bottom right (this "can" be frustrating because you will need to press in on the release button at the same time as pulling on the connectors). Once you have these out, you can finish removing the metal box. The TCM is one of the two gold boxes bolted to the underside of this silver plate - the one with two connectors into it. FYI, the other box is the engine computer. 3) If you are having erratic speedometer and drivability issues, the TCM possibly needs to be rebuilt as the capacitors on these go bad. I've been chasing the same problem with a 93LX for 6 months - not fun or easy.
