My dads car is having issues with throttle and shift flares and shifting in (I recall) 3,4,5,6th gears are inconsistent.
it's an LS7 block, lS3 heads, magnacharger 2300 with 13 pounds boost. Trans is 6l80e with new clutch packs and 3400 stall converter. ECM is from a 2010 Camaro.
can you help rectify the transmission shifting issues?
