1-2 squeak

Trying to grasp whether this is cause of concern or not...

Made a near-WOT 1-2 today.. I had heard this "squeak" before.. but it was so minimal I thought I was hearing things or maybe it was tire.. but what I heard today was fairly distinctive and definitely not tire. I reminded me of the same squeak I could hear when turning the driveshaft one way from underneath the car. Normal driving 1-2's are normal and firm. I thought I heard a smaller version of 'squeak' when it shift 2-3, today as well.. but I can't remember for sure. Thoughts?

Trans is recently J-Modded (mild w/gear) with Mark8 TC. Current chip tune has shifts fairly firm.

Belt slipping maybe??? You may need to change belts.

Fan belt. Get a belt like a Goodyear Gatorback or a Dayco Poly Cog. They grip a lot better.

Ok... That's simple enough.. don't know why it didn't even occur to me.. The belt is new though, not but a few months old. Gatorback it is.

I can testify about the Goodyear gatorbacks. Best belt ever - no slipping ever - no noise - and with 60K on it it looks like new.

its a very common thing with a n/a 4.6 engine. You can put underdrive pulleys on it to tighten it up or you can just live with it. My 95 did it all the time.

Heh, I just wanted to make sure I wasn't looking at soon-to-be trouble. When I took out after putting in the converter jmod and gears.. when I hit it for WOT it chirped 1-2 quite nicely.. standstill no-brake burnout did good as well.. and for a while... near-WOTs I never noticed the sound.. couple times between then and now I had heard it ever so faintly. Today though was pretty noticeable so I took concern. I'll slip on a gatorback and see how she goes sometime later.

You sure it's not the tires?

Yea, I'm pretty sure... since belts were mentioned it kinda clicked.. since it does sound very much like a squeaking belt. The tires never made that high pitched kind of chirpish squeaking noise when the barked 1-2. I had to pretty much hit WOT to get them to also.. I wasn't at full WOT when it squeaked so well this afternoon.

Yeah, but did you just do the Jmod and gears?

My 94 Mark VIII does it too. 6000 rpms.. eeeeeeeee shift.

Like a slight, and very quick high-pitched belt squeek.

but this is good! That basically means your tranny is shifting so fast, that the engine rpm drop is almost instant, and you get a slack-drop in the belt. This also happens on radically cammed motors when they are revved. the idle recovery is so instant, the belts often flap for a second If you give it a double-rap of the throttle, you can get a slight, and quick 'eek"

I have a brand new belt, and idler pulley. I havent heard the little "eeek" in a while. But, I'm sure it will be back.

Oh, and BTW, our 97 does it too...it has a SCT chip, so the shifts are a little quicker than stock...

sleep tight...its fine.
