Been building a harness for a 5.3 in a 1969 chevy shortwide the past few nights.
About to pin the connectors and have a few questions.

Owner is using a TH400 and will not be using a VSS. I've explained the issues with not using one and he'll add one later maybe but not now.

I figured I would simply program as a manual (I warned him of possible idle issues with this).
while repinning however I came across the CPP and got to thinking.

If it's programmed as a manual,it would not be able to control TCC lockup right?

The harness is hasn't been totally wrapped yet,so if I need to add something now is the time.

How has everyone else dealt with convertor lockup,programming,pinning etc.. for a TH400?
I know nothing of the TH400 at all,I have changed a few camaro's over to manual after they swapped but it was a quick program and never heard from again as I remember.
