Got a weird deal I cant make sense of
5.3 Colordo , Magnacharger , Doug's TriY headers
Tune and combo is over a year old and worked great. *pre trans mods *
Customer had the 4L6o style trans built buy a known good builder
added in a mild stall Edge Racing small body torque converter to the mix
Symptom
has an additionl shift / hickup at light throttle @ 17-22 mph in 2nd gear
in the data logger shows the TCC going into "Release Delay / FS"
Despite the minimum lockup speed is set to 42 MPH
Tune file, datalog, and config file attached
Datalog shows issue at 3:01
I'll take any help I can get
