[2001 Accord Ex]

I've been having some issues with the transmission for a while and now the TCS light is on, the D4 light blinks, and I have to manually shift from 1 to 2 to D3 to D4.

I'm told by a transmission shop, who can't get me in for a couple days, that it is likely wiring from the TCM to the tranny.

Where is the TCM?
