Looking to control 4L80 behind 396 BBC with no crank speed sensor. Anyone using HEI tach signal for RPM. Also like to hear if you are currently running or have setup this combo with 0411 or other OEM ECM. Lots of options to spend $$ on controllers, however many folks want 4L80 without the expense of aftermarket controller and still have an operating automatic trans with TCC lockup. TIA
