Adjusting the TV cable is going change line pressures, not shift points. When I had my AOD, EVERYBODY who was anybody in this racket said "don't touch the TV cable". I heard horror stories of guys doing adjustments and days later the trans blowing up. With the change of gears, it will rev the motor quicker thereby shifting sooner. This is how my car reacted when I did the 3.73 swap. Just my opinion, but if you do highway driving those 4.10's are gonna get old quick. Even now I'm considering going back to the 3.27's my car came with. Like I said it's JMO.
