What did you do to get the lockup to work in the trans?

The computer also controls the lockup in the transmission.Unless you swapped in a th350 or 400 you need to get that fixed.

Computer or no computer the TC will never lock up once you've removed the cc-QJet and cc-HEI. You need a stand-alone system to lock it up for you- there are a couple different varieties available on the market. I never bothered in most cases, but it can shorten the life of your trans.

On older cars like this the ECM isn't necessary once you've gone this far. On later vehicles (around 1991-up) you probably still want the ECM on board to run a few things like the speedometer for you.

There are several choices, but I suggest the one from PainlessWiring.

and you can pull the ecm out along with the entire ecm harness, through the pass side fenderwell. please don't hack it up and leave pieces dangling.

sticky on top of carb forum with ways to control converter lockup.
