loud noise?

[elvis3006]

when driving,and i come to a stop, i push in the clutch to change gears a loud groaning noise rises out from beneath the gear selector. why is this happening,this only happens when i am stationary. i have a 43 GPW. thanks for any help.

Groaning only happens when the clutch pedal is pushed in? And only when stopped?

May be a bad throwout bearing from the description.

Did it happen after sitting un-used for awhile ? Years ago I bought a 55 GMC truck that had sat. When I first got it running and pushed in the clutch it made a heck of a groan, ended up being rusted/worn out clutch pedal assembly. I hope its something easy , good luck!

yeah this only happens when i am stopped,and i push in the clutch and change gear.

I suspect that it's a dry transmission input shaft pilot bushing.

would changing the tranny oil stop this,could i be low in the oil? also i noticed it only wants to make this loud groan when i push the clutch all the way in.

If the noise is the result of a dry pilot bushing, changing/adding gear lube would not help. The bushing is ahead of the tranny and pressed into the flywheel end of the crankshaft and can only be lubed after the trans. assy. is pulled back out of the bellhousing giving access to the center of the flywheel and crank. With the clutch pushed all the way in and the engine running, the trans. input shaft doesn't turn but the flywheel and crank do, the input shaft rides on the rotating bushing, without lube the bushing and shaft give a vibrating, growling noise much like you describe.

I have a 43 Willis that had the same noise...I replaced the throw out bearing and all is well.
