Transmission Slipping When Accelerating
I haven't been able to determine the source of my C4 transmission slipping when I'm accelerating. It used to slip at gradual acceleration around 30 mph but after I rebuild the transmission then that went away. It now slips around the same speed when I floor it. I played around with adjusting the front band but that didn't have any effect. I also adjusted the vacuum modulator one turn counter clockwise and that didn't help either. Not sure what the next steps should be. Continue adjusting the vacuum modulator or look elsewhere. I was wondering if the torque convertor could be the problem and need to know how I would evaluate that.
