strange squeak noise after vette servo install

[drewxjn]

Installed the servo and driving normal it shifts great. When accelerating faster it makes a strange noise when shifting into 2nd. I read over on performancetrucks.net or something like that, that a guy had a noise and it was due to the serp. belt. Just wondering if any one else had experienced the same thing. Oh found the link again.

Let me know what yall think. TIA!

mine does it too. I would imagine its the serpintine belt not keeping pace with the RPMs during the shift. I put replaced both belts and it still does it. almost sounds like a blowoff valve. Mine will do the 2-3 shift as well, but it slams when it shifts lol, no slip. I doubt it would do it stock since the shifts aren't as firm.

Sure it is not the tires chirping?

I love this forum, dont get me wrong, but PT is the forum you want to post this question on. Trust me.

Ok thanks guys. I know its not the tires, thought it was the servo in the case messed up. But after finding the pt thread i am starting to think its the serp belt more and more. If it is the serp belt how long will it last slipping like that. And if i do replace it will it keep slipping like bottomline2000s. Is there a way to tighten the belt more so that it wont slip? Thanks again.

I got my truck tuned and haven't put my servo in yet and I have the same problem when shifting into second. Wonder how bad it will be post servo..

I squeek the crap outta my belt going into second, and chirp it into third sometimes..

Tune, exhaust, cai, both servo kits, fans, etc..
