There was another thread going that I jumped on for information on this but I wanted to start another one because I'm not 100% sure I'm having the same issue as the other person. Besides, I would also like to better understand what's happening in this portion of the TCM tuning so... here we go.
I have a 392 with a cam. I think I've adjusted the idle RPM and airflow as much as I can. When I'm at stop lights, in gear and foot on the break, the car will sometimes do a little bit of jerking. It's worse when the engine is still warming up but it's still there even after driving around for 10+ minutes or so. It's pretty minor but it's still noticeable enough that I will sometimes put the car in neutral just so I don't feel like I'm being shaken up while I'm waiting for the light to change.
Is there anyway to adjust the Torque Converter settings so that when I'm at 0% throttle, idle conditions, 0mph / 0 rpms on the transmission exit shaft, the TC is really loose? I mean, when I let off the gas, I still want to idle forward slightly. That's standard behavior but when I put my foot on the gas, even just 5% throttle, it returns to normal operation like it is now?
Otherwise, the car performs great. If I could just get it to not shake me up while sitting at a stop sign, I'd be golden.
