Just changed the serp belt and...wtf

[scgoldtater]

Ok guys I just changed out the serpentine belt on my '00 Yukon xl. Figured I would do it because the ac belt tensioner seized up and threw it off.

Now I put both those belts on the transmission is jumpy as all hell, big bang from 1-2, 2-3 gears. It was fine the day before, so it got to be something I did

So did I mess it up or what? Need some advise thanks

Take a picture of your belt roiting

Yeah the routing might be the issue.

The small belt runs the AC compressor and nothing else. The long belt turns the alternator, water pump, and power steering pump...has an idler pulley and a tensioner pulley. There is no way to route it wrong....but even if you could figure out a way to screw it up, it would have nothing to do with the transmission.

Well just took a fresh look and seen I forgot to hook the airflow sensor back up. That make sense and I am dumb for working in a hurry
