Okay thanks all. Just broke out service manual and reading what is basically this method. Need to get back out there and do this

Btw if you're asking yourself "hey stupid, why didn't you do this in the first place"?! Because I've adjusted shift points on several Mopars before simply by moving throttle rod by loosening bolt at the block along side trans and not adjusting line pressure. I've had mechanics who are installing trans for me adjust line pressure and later tweaked points with throttle rod. Looks like this one is going to be a little more involved but it's okay I need to learn.
