64 Manual Trans Tick
I have a 1964 F100 with a 4-speed manual transmission that has started to tick. The tick just started one day and has been there since. The tick speeds up and slows down with the engine and occasionally goes away completely but not for long. When I get up to high speeds, it goes away completely. There's no change in the operation of the transmission; all gears are easy to get into and out of and there's been no power loss. I know this is pretty vague and the transmission is probably in need of a full overhaul but I thought I'd try asking here in case it's something common that I could take care of or stop fretting about. Any thoughts? Thanks in advance for any input!

one of the teeth on the input shaft has gotten a nick on it. in every gear but 4th, it's driving the cluster shaft under load, so it makes more noise. in 4th, it still turns the cluster but it's unloaded, so theres no noise. thats why the noise goes away at higher speeds. could be the input bearing also, but those usually go from tick to growl in a short period of time.

Are you sure the tick tick tick is coming from the transmission?
This is a very common noise on these trucks with 1-6's and 292, as they have mechanical tappets that have to be adjusted every so often.
Could also be related to the exhaust system's cross over pipe (292), the exhaust manifolds of all engines.
Ford did not install exhaust manifold gaskets on I-6's or the 292 installed in F100/250's, they were "metal to metal."
The manifolds begin to warp, ticking begins. If aftermarket exhaust manifold gaskets were installed, by now...they could be defective, causing tick tick tick.

So I listened carefully to the tick driving home last night and have a little more information that might help diagnose the problem. The tick gets faster and slower with RPM speed in every gear. Sometimes it doesn't happen at all then all of a sudden starts and sometimes stops in the same fashion. The volume is erratic too but it never gets too loud, just loud enough for my imagination to run wild. I know it's not a valves noise as I'm familiar with that sound and it feels/sounds like it's right next to me coming from the stick. The engine BTW is a inline 6 223.
I'd like to eventually change the gear ratio situation this truck has to get rid of the granny gear (which I never use) and get a little more out of 4th (which starts winding out around 55) Not sure exactly what the best approach to this is; a new transmission, like maybe a 5 speed if I could find one or a new differential. Maybe rebuild this transmission with different gears? Is that even possible? Anyway, as you have probably figured out, I'm still a bit green with truck mechanics...

I am in ND camp, not clear the 'ticking' is transmission related, especially when it come/goes with increase in RPM. Not sure it's possible to separate the sound coming from the transmission to that of the engine? Perhaps when the 'ticking' surfaces place the trans in neutral with clutch disengaged while at same time increase engine RPM?? I have had similar experience with a 'U' joint, found the U bolts had worked loose; tightened/greased and no more noise, recently replaced.

The problem associated with tick tick tick is, it radiates thru the entire power train. So it could be exhaust manifold related, bad u-joints, but...
I doubt it's transmission related, as I've never heard of any M/T trans going tick tick tick.

while the truck is sitting still, and it does it with the clutch engaged, but not with it disengaged, it's your input shaft. could also be on the cluster shaft, but less likley. the input shaft and cluster shaft/gear still spin when in neutral sitting still, till you push the clutch. drain the trans, look for chunks, shavings, debris. hopefully it will have a magnetic drain plug.

I crawled under the truck and took a look at both the universal joints, grabbed them to see if they'd move by me pulling on them, looked for loose bolts but they both seem fine. I fired up the truck to see of the tick comes and goes when pushing the clutch pedal but the tick wasn't there to begin with so I'll have to listen for it tomorrow.

F350/700's with 272/292's came with heat shields.
Aftermarket exhaust manifold gaskets were available for these Y blocks from auto parts stores.
There were no I-6 (215/223/240/262/300), 221/260/289/302/351M/351W/400 or FE exhaust manifold gaskets factory installed either.
The FE's came with stainless steel heat shields.
