I am getting what sounds like a belt sqealing during the 1-2 shift at WOT. Anybody have a clue as to what it might be?

 

It's the belt squealing. Doesn't hurt anything. Your engine slows down during the shift faster than the accessories can slow down, so something slips a little and squeals.

 

Thanks, that is what i figured it was. I didn't know if I needed to take it in and have it checked out.

 

I had this w/ the combo of new alternator (bigger 160A) and the shift kit...My stock alt is back on now (rotor went bad...wrangler repaired under warrentee, but just haven't put back on) and no problem...I think if I install a longer belt w/ the bigger alternator, all will be well.
Good luck.

Mine does it too

 

mine did it when it was stock too.

 

mine does it also,how can you get rid of this,oh i have a 05 with 5.3

 

mine does it on 1 to 2 shift and 2 to 3 shift

 

Mine used to do it on the shifts but not since i changed belts. I went with a goodyear gatorback. No more belt slip when it shifts, however I do have some belt whine, but it sounds good. Everyone thinks its coming from the charger so i dont say anything different

 

i had one them on my old truck . nice belt love the whine it makes . just havent got to the chance of changin this one
