So far I have had a nice little nightmare with my transmission. I decided with the advice of my mechanic to drop a 350 sbc in to my 96 blazer. So now I have a smart trans with a stupid motor. Needless to say I'm in limp mode. After the 2 g's ive already dropped in getting this thing put together I'm out of cash to afford a $600 trans controller. So I hijacked solenoid control onto switches. I have successfully obtain gears 1-4. I have done this on the ecu side of the trans harness as I am not dropping the trans to see my pin outs on it for my diagrams. The issue I am now dealing with is i want to manually control tcc lockup but i cant figure out what wire to put the switch to. And do I need to have it pwm controlled. I do eventualy plan on creating a trans controller with an arduino board in a couple weeks but i still need to know which ire is the tcc.
