Re: A few lt1 ?'s

Just wire the TCC through the 4th pressure switch in the valvebody. Make
sure the pressure switch is a normally open switch. Then it's totally
automatic and disengages when the transmission downshifts to 3rd as you slow
down. Downside is that you get instant lockup when you hit 4th gear.
