I was on my way home from work and while i was driving at steady speed it seemed like my tranny was shifting down and then right back up again RPM were changing quite a bit. It has never happened before and then when i got back in town and cruising at 50 to 60KM/H it started again. I have no mods yet except for exaust and air i ntake, could this be a problem with the TC or should i have the bands adjusted? Anyone else experience this.

 

Guess we really need to come up with a pet name for this problem to aid in searching(you know like we have "death wobble", "dead pedal", etc...). Easy cheesy start for your prob is to test both of your batteries to insure they are good, and then clean the terminals and reset the APPS.

 

Check the wire coming off the back of your alternator. I had the same problem, cleaned the contacting surface on the wire, the truck is running like a striped-*** ape.
