The ECM controls the ignition timing and the torque converter clutch of an automatic transmission with such a feature.

It also controls some emissions equipment like A.I.R. and EGR, but I'm assuming since you're eliminating the ECM and going carb, that isn't something you're concerned with.

im not concerned with emmisions really ill find a way around those but i do want it to run properly. so can i just get a msd ignition and then isnt there a $20 part for the convertor?
thanks for the help so far

The only "kit" I have seen lately was in the $160 range.

For a TH700, you can modify the 4th gear pressure switch so it locks the TC whenever you're in OD. That may be about a $20 mod.

ok the trans will be a 700r4 and i swear a saw someone say summit sells something cheap to do that ill have to look into it

There might be something else out there, that's all I could find on Summit or Jegs.

Youll need a non cc distributor, carb, manifold, new throttle linkage, a mallory bypass style fuel pressure regulator, and some way of locking the converter. There is a tech article in the tech section of thirdgen.org there details everything. Good Luck.
