02 TB TCC unlocks/locks at hwy speed
2002 Trailblazer 4x4 4.2L I6 4L60E
When cruise control is on, it switches often between lock and unlock. Hold speed steady with gas pedal, and it stays locked in. Obviously getting better MPG with pedal and not cruise.
Because of the complaint, I 'moved' the TCC lockup point down (less TPS) and unlock point up (more TPS), but that did not help. Based on feedback, it didn't even help. User says it did this with stock tune as well.
Am I missing something in the tune where I can change the cruise TCC lock/unlock?
Thanks for the help!
