I have a 1997 dodge dakota v8 mangum i have been having this loud annoying whinning noise coming from underneath the truck by the tranny and i can hear it from inside the truck down by the gear shifter, it only makes the noise when i give it gas ican push in the cluth while driving with no gas and it goes away but if i ouch in the clutch and give it gas it gets loud. i just changed the serpentine belt and tranny and transfer case fluid. help me please

 

throw out bearing perhaps

 

typical gear whine?

 

x2 for sure.

 

where are these throw out bearings located and is it an easy fix i got underneath the truck today and it sounds more in the tranny towards the back end of it

 

The throwout bearing is part of the clutch.

My guess is that it's gear whine or an output/tailshaft bearing.

Did you have it idling in neutral w/ parking brake on while you were under it, or on jackstands in gear [IMO not a smart thing but sometimes necessary]?

 

i had it in nuetral with parking brake on and a friend giving it gas it got worse when he gave it gas buticouldnt really hear it once it warmed up.

 

ok, so it makes noise when:

clutch is engaged [input shaft of trans is turning]
trans is in neutral [no gears are meshing]
Trans is cold

Sounds to me like a bearing on the input shaft? The bearing loosens up as it gets hot?
