Question

[Rick Nelson]

Has anyone ever experienced this? I have reverse bur no
Forward high or low

[perry kete]

Could be stuck in neutral?

What happens when you push the clutch (left) pedal down hard? Do you have neutral with the parking brake lever halfway back?

[Rich P. Bingham]

Nope. Never.

Let the guessing begin. If you have reverse but no low, the "easy" answer is that the low band is A: missing (?!?) B: totally worn out C: way out of adjustment.
The "hard" possibility, perhaps the drum rivets have sheared off the gear shaft (really rare).

No lockup in high -? Multiple possibilities, the simplest being the clutch linkage is out of adjustment. Disconnect the pedal from the throwout lever, make sure the hand lever cam is not interfering and you should be able to tell if the clutch has engaged.

If not, follow the manual directions for adjusting the clutch fingers and all pertinent linkage. Look first to be sure the clutch spring is not broken.

Good luck !!

I guess I should clarify, I am not new to model Ts but not claiming to be an expert. Just out for a drive one day every thing working great, stopped at a stop sign and that was it no strange sounds, nothing, just wouldn't go forward. I restored it in 2009 and replaced anything that was bad (or so I thought) I was just hoping someone would have had similar problem. I guess I will have to do what I figured all along and pull the engine.

It may well come to that. Interesting case, I hope you will keep us informed of what you find out as you progress to find the cause.

Have you opened up the transmission cover? Look inside and depress the pedals and see what’s happening. You may have already done that.
Check the linkage inside and out. Check the pedal shaft pins. Maybe a pin sheared.
With the engine off put the handbrake in neutral. Then try to turn the crank. You should be able to do that with not much resistance. Then put the handbrake all the way forward and you should be able to move the car forward a bit or at least some. Those are simple checks to start with as you might know already.

Other internal things might be the clutch drum set screw may have gotten loose, or something similar.

Hope it’s something external and not something that’s gotten loose inside the transmission.

Not exactly the same pattern, but I have experience a locked transmission with only high, no clutch and no low (did not try reverse) and that turned out the be a broken tooth that have blocked the triplegear. It was a rebuild of the gearbox :-/

Thanks for everyone's input. I am probably not going to
Mes with it until spring. It is tucked away and the snow is falling. And I am working on a 17 couplet for the winter
