I am trying to figure out why my tcc slip is so high? Can I get some help? the trans is a 4L80e with a ck performance D3 valve body, a triple billet triple lock up 4300 stall converter , and I am getting 1200-1500 tcc slip in 3rd gear at 5000+ rpm. what can be adjusted to lower the slip under full throttle.
motor is a 6.0 with vsr 88mm t6 and I am only running 12# of boost.
tune and log attached.
