"For firmer shifts, you could also do the same thing from the TCU to 'duty control solenoid' A to remove the signal. This would force full line pressure into up shifts. For 4-wheel drive 'lockup', you can disable (switch off) duty solenoid 'C', this will lock the car in 4 WD (50/50). You could probably wire all of these circuits into a single switch (say under the accelerator pedal, or tied to the 'Manual switch"). This would be great for racing."
I am mostly interested in this for manually setting the diff to 50/50 (I live in Maine with bunches of snow). Thanks!

That FAQ was written some time ago. A lot of information has been leaned since then.
Turning the A solenoid off is not the best way to do it, it produces a number of other problems. The best way to help the gear shifting is to fit a Quick Change.

Locking the C solenoid should only be done when running the 1/4 mile.
