TR4/4A 1967 Tr4 a Transmission noise

[Oldcarhobby]

Greetings, I am starting to hear a slight “ whuring” noise that appears to be coming from my
Transmission area! . When the car is in neutral & running I can make the noise go away by pressing my
Clutch all the way in ,upon releasing the clutch the noise will start when the clutch is about 1/2 out .Is this an
Indication that my release bearing is on its way out ?. Is there any other test I can do help diagnose this noise problem .? I do have overdrive …. Many thxs for your help

That might be the Throw Out Bearing itself spinning on the fork.
If so an anti rotation pin would stop the rotation and the noise.

Simple things first: did you check the transmission oil level?

I can't think of anything else that doesn't require pulling the transmission. It doesn't sound to me like the kind of problem that will get more expensive to fix if you don't do anything; perhaps something in the clutch or the input-shaft bearing. I think it's safe to leave it alone at least a little while and see if it gets worse.

Thank you for your input, I will recheck fluid level again , and continue to monitor noise level.

The release bearing would make noise when pushed, not released. There is a slight chance that mis-adjustment could cause noise, like Ken said.

The most likely cause is the needle bearings in the countershaft are wearing. They normally make a hissing, whirring noise as they slowly die...and it is most pronounced when sitting at a stop in neutral with the clutch engaged. At the early stages you won't hear it when driving.
