2004R Calibration
Has anyone been successful in raising the part throttle shift points on their 2004R transplant. I realize it was calibrated for a high rear gear and I have a low gear, 4.10 to be exact. It thinks I'm traveling much faster than I am due to the increased driveshaft speed. The think will go into 4th by 35-40 and doesn't really respond to 50-60% throttle as I would expect. Yes the TV cable is properly adjusted and my understanding is this is not how you set the shift points.
