I have a 2000 4.8L with a 78/75 turbo and a 4L80e transmission. The transmission has an HD2 shift kit and a recently installed (Used) Yank 3600 stall converter.
I noticed something interesting since the converter swap. There have been a few times where the vehicle starts to pull, RPM shoots up and mph barely increases.
I got a datalog of it tonight. The pull starts at 7:06:19 and the actual jump is at 7:06:26. MAP also decreases in this time which also makes me think there is less load on the engine.
Thoughts?
