It’s fairly erratic, sometimes it shifts alright but at full throttle it won’t upshift until I let off and it occasionally flares when upshifting. I read a PDF I found here about transmission tuning and there’s only a short page at the end about the ‘85 system and I’m not sure if they’re supposed to have 10” of vacuum at the trans at idle like the older system. I have a red restrictor at 63 and a black one at 63a. I also see that the Transducer has an adjustment screw, could that be part of my issue?
