1st-ON ON
2nd-OFF ON
3rd-OFF OFF
4th-ON OFF

So for me, the tranny would default to 3rd between gears. I could probably get away with two switches.
both on would be first,
turn off switch #1 for second,
turn off switch #2 for third,
turn on switch #1 for fourth. I could run a switch for TC lockup, but my question is do i need to unlock when shifting or can i just leave it locked? probably unlock for downshifting/stopping. i don't think i have to be spot on with the downshift rpm since my stall is AROUND 1400 I think.

what do you think?

I NEED A TACH DON'T I??????
