700r4 Noises??? Easy Fix? Need help ASAP!

When I put it into drive and punch it at any speed, it makes a raspy Keeeesh sound. It only does it in drive. 1st and 2nd, no sounds. Is it an easy fix? It runs good, just full throttle it makes a funny sound.

I dont know what exactly the sound is which you are referring to, but mine has made a whining sound before at WOT. A mechanic I know said that whining at WOT could be from anything inside the tranny like bearings or the like. Because it is getting worse, it sounds like you need to ask a tranny shop.

Good Luck

as a long shot check your tranny mount and make sure it is not split in two allowing the tranny to jump around under high loads.

A bearing problem would suck. It only have 80,000 miles on it. Oh well. It sounds like the problem. And still, only getting worse.

Re: 700r4 Noises??? Easy Fix? Need help ASAP!

check your mount as stated previously the torque arms break these easily.
also if thats good then it is an internal problem which needs to be fixed now.
mine made that type of sound and it was the drum that the 2/4 band applies to had been squeezed so hard that it fanned outward to the case almost cutting the case in half. (this was from blocking the 2 accumulators like the TCI super street kits)
