Hamster wheel in my tranny

[NorCal_Chris]

So recently ive developed this annoying squeak that sounds like its coming from my tranny/torque converter area. Only happens when the truck is warm and,at idle, in gear It is not noticeable while driving. Did a breif inspection today, flexplate is ok, bolts ate tight. I need to get my wife out to put it in drive with the brake on so I can get under it.

Any wisdom on what this could be? It is quite annoying. Th350 anf I have an aftermarket sfi flexplate. Trans shifts great.

Anither problem I had maybe related was when I was out wheelin and on a sidehill slightly downard I couldnt get my truck out of drive. I ciuld go d 2 1 but wouldnt shift past nutral because it was acting bound up. Had to put the t case in nuetral and get winched backward a ways to flat ground then it worked again.

Does it go away when you increase your RPMs with your foot on the brake?

You're SURE it's not a flexplate issue?

it will increase with rpms a little, then goes away. The flexplate isnt cracked, i checked it a couple times. I will check again tommorow for good measure and try and get a vid up. Ive had a cracked flexplate before so i know what that sounds like, a tap tap tap. This is a squeeky wheel noise

Check all your motor/trans mounts. Something was twisted up enough to keep the shift linkage from working through it's range. If the mounts are gone something may not be sitting right causing a rub somewhere, but only in gear and with that idle 'frequency' or oscillation of the engine.

This happened in my sandrail once. Turned out to be an actual hampster.

Lol matt.

I will check mounts hopefully tommorow. Damn rain today. Didnt think of that
