So rundown on my truck
2014 Silverado
5.3/6L80
rebuilt two years ago (engine and trans)
all GM parts except:
LSXceleration stage 2.1 Cam
Speed engineering long tubes and Ypipe
3.5 in exhaust into Flowmaster 70 series
6.2 intake and TB
Comp cams actuator lock out kit
LT4 springs
hardened stock length pushrods
everything else new GM parts, except for crank
Stock GM converter
Sonnax zip line kit
all new clutches and steels
RECENTLY replaced valve bodies (missing checkball)
Cant figure out this random delayed shifts. Doesnt seem to matter if its cold, hot etc. This is the tune Ive been running in vehicle the longest. Up until I had the missing checkball issue, it would very rarely flare slightly going from 5-6th. Usually run it on E85. Everything on engine side seems perfect. When trans was apart, fluid still red and no metal, etc. I feel like its tune related, because I can load an older tune, and it changes how the trans acts. Shift times are all over the place. Ive done the trans adapt reset also. Somebody help! lol
