Once again I need advice/assistance in identifying my problem. Today I took the car off the jack stands and took my first trial drive. Motor started great and purrs like a kitten. Released the emergency brake (car did not move/creep forward), reduce engine speed and pressed the clutch pedal - what a noise but the car did go forward and when I engaged high it ran like a dream (no noise anywhere). When I turned around the reverse pedal made the same grinding noise (like an ice crusher). I tried both low and reverse several times and the noise persists. Did not notice it on the brake but I did not use the brake much.
I have reviewed previous threads about noisy transmissions and it seems most people believe the problem to be rear end instead of transmission. I have not yet checked differential for filings or opened the transmission inspection cover.
Anyone care to speculate what I might be facing or what checks I should make? Is there any additional information that would help?

Frozen triple gear bushing. No noise in "high" because you are not using the triple gears. The whole mass is moving as one.

Mine was kinda's noisy for lotsa' miles, until it jumped some tranny teeth and sheared off the crankshaft flange.



One bushing was frozen solid to the badly abraded pin.

Check the rearend for babbit thrust washers, regardless.

My 14 transmission is noisy, hope the low speeds gear is in better condition than the above photo. I'll let you know asap.

Ice crusher huh? So it's more of a CRUNCH?
Been there and done that......rear end.
In my case it was the badly worn face of the upper driveshaft bushing that allowed the pinion to crawl into the differential gear teeth.
If I was a betting man I'd have bet a $1000 the trouble was in the transmission.......and I'd have lost.

No noise in high means the rear end is not the problem. You need to take the transmission apart. Most likely it is worn out and needs a rebuild.

No one ever changed oil in their Model T way back when, at least most people did not. This is the reason most of them have trashed out clutch hubs and shot bushings. Once in a while you find one where the oil was kept clean, then there will be no wear at all.

Agree. Rear end noise would continue in all gears.

With an over and under my 22 is started out of gear and left running for a few minuets to warm the oil on the stock steel clutch plates so the car does not creep.

As soon as the brake is hit to stop the transmission from turning to engage the over and under you hear the triple gears spinning.

I have done several experiments learning the reasons triple gear bushing lock up, one of eight reasons is debre in the oil.

On careful inspection of all the parts involved I noticed something not mentioned in other posts some one might know about.

Ralph's picture shows three cast I will call them deflectors in the outer part of the fly wheel dish. I have one fly wheel without them and others with them. If some one can tune me up on them please do.

I glossed over that part >>> when I engaged high it ran like a dream (no noise anywhere)

Paul: If you are refering to the three lugs cast into the flywheel dish my guess is that they are locating pins for the machining process done by ford. I don't think they have anything to do with oil distribution.

I dont know Jack but they are not machined on any side and the fly wheel without them is machined for a starter ring. They are spaced an equal amount ahead of each triple gear. Oil enters on the front or flange end and exits on the rear. If you look carefully oil comes under the dished out flange end of the triple gear.

What's the history of your car? Many a transmission with new bushings howls like crazy because the spur gearteeth are making contact in a new spot rather than their time worn original location. Well worn bushings seldom cause any problem with the transmission. Its the most durable part of the driveline.

I have a few issues with fit but they will come later when something is I can prove!!
Cheers!
