Are they referring to the clutch solenoids for gear change and/or the torque converter solenoid(s)? If you can get a hold of some schematics for TCU/TCM output, it may be possible to find the voltage to energize the proper solenoid(s) at the flick of a switch, while isolating the TCU from that operation. It will likely throw a code... plus I would recommend setting-up a switch/circuit to go back to stock for decel, shifting, etc. You could get complex and use the speed sensor, RPM, current gear, TPS, and wire-up a fail-safe mechanism.
This mod can can cause harsh shifting, engine lugging, and other manual trans-like behavior -- including the good stuff, like control over the TC and better FE.
Best FE...
