Re: tpi to carb swap. tcc question

all I did was cut the blk/wht and the tan/blk wires going to the aldl connector and put a switch on it. when the switch is on the tcc will lockup when car is in 2nd 3rd or 4th gear.I only turn mine on when cruising on the highway. I use a trans temp gauge and if it heats up in the city locking up the tcc will cool the trans down.

No, the ECM won't control the TCC after you've removed all the sensors.
