has anyone else heard a loud screech when you accelerate from a dead stop or under 5mph and then let off at about the same time the tranny shifts into 2nd?

 

I got a screech when it shifts to 2nd after the shift kit was installed, I think it is the belt. Only does it when the foot is on the floor. wish it was the tires, if I accelerate on a curve the tires will chirp or if the road is wet the rearend will break loose. scares the crap out of the wife...lol

Just my going-bald tires! LoL!

In all seriousness, I had a problem with a screech when tranny downshifted from 2nd to 1st for a while; I climbed underneath the sucker and soaked down the tailshaft with WD40 and haven't heard a peep since.

Hope this hepls

HI!... Mine used to do it after I installed my 1ST shift kit and ASP power pulleys. I got a 1 inch shorter than stock belt and it has'nt sqeeled since. Just a thought.

 

i'm gonna try tightening it a little,then if that doesn't work i'll get a shorter belt,thanks for the input.

 

What is the part number for that shorter belt and where did you get it? Thanks

 

I have had that noise for awhile then one day my ac took a crap and i took it to ford and they said my ac blew and i had metal pices in my lines its still in the shop its been their for a week now but i'll let ya know if the noise gos away.
