time to learn how to double clutch.
shift into neutral and rev the motor
then shift into second.
practice makes perfect

Double clutch yes. That's what it takes, since these are not synchro transmissions and they are straight-cut gears.



I might add to the "rev the motor" --- Rev it to about the RPM's that the engine will be at when it is in 2nd at the speed you are going. It will seem to be pretty high, but practice will make the difference. That being said, I don't downshift nearly as much in the A as I do a modern car. Even with 6 years of practice, I occasionally don't get it quite right. My own opinion is that they did not downshift on the fly back in the day as much as we do these days with synchro trannies in modern cars.



Good luck.

I tried that still grains

Because of the ratio split, you need to rev the engine more than you think. It's like shifting a four speed from top directly to second.

The manual itself says go directly and immediately from third to second without pausing or double clutching. I find it only works that way at speeds under 20 mph. Otherwise double clutch.

Yeah, I tried it a couple of times, but one has to be careful with that. I double clutch out of precaution.

Agreed. I tried to shift that way at 10mph or so... never again. If you can rev match, do that. I tend to drop into 2nd between 15-25mph. If the car starts lugging up a hill I'll downshift at 25, taking a corner on a flat road I'll let it slow down to 15. I know what the manual says but under any sort of load 12-15mph in high gear lugs the engine too much for my liking.

Down shift way before you need to. If you miss the shift and are depending on it to slow you down on a grade, you may be in trouble.

Mitchell makes a synchronized Model A transmission that is in the stock box.

[8EL]

The Ford mode A sliding gear 3 speed standard transmission uses straight cut spur gears without synchronizing drums. Therefore it needs to be double clutched to shift up or down to mesh these gears without grinding....Henry referred to these transmissions as "crunch boxes", preferring the planetary transmission found on the Model T....But that's another story for another day.....

What worked for me was two things: first, get a speedometer app on my phone and mount it temporarily in front of me so I could see my speed. Second, find a big open property with a winding drive to practice in. I used a local cemetery.

The actual operation is that you shift from 3rd to neutral, let the clutch out, blip the throttle, clutch in, and ease the shifter into second. The practice part is needed to train your ear to know what engine sound corresponds to being under 20 mph. That’s really all there is to it.

Are you trying to downshift in situations where you actually need to? Or,just where you want to,like a modern car. I had to educate a friend when he bought an A.He was trying to shift it to slow down,and trying to shift down when there was no need to.If a car was making a turn in front of him he kept wanting to drop a gear and hit the throttle to go around it.He kept wanting to drive it like his three on the tree Falcon.It took him a while to come to terms with the slower pace of operation in the A.

Excuse my ignorance on the age old "Art" of double clutching. When you rev the engine in neutral, to rev match the gears, is that with the clutch out? Then clutch in and down or up shift to desired gear? That to me would be "double" clutching.

Thanks forum, Your The Best!

Yes, clutch out.

[Big hammer]

Ford’s owner instruction manual says to up shift 1-2 at 5-8 mph, up shift 2-3 at 15-18 mph, no need to double clutch at these speeds! If you’re grinding the gears at this recommended speeds then you have other issues like to fast of an engine idle, engine not returning to idle, transmission has too lightweight oil. If you get it right you can slide the gears without using the clutch ( just ask a good semi truck driver ) on a good day I could do it but I don’t recommend it. As for down shifting double clutching is a must that I couldn’t get right.

So I brought home my avatar truck. It was a pretty easy drive up onto the car carrier/flatbed.

Once home I decided to "get familiar" with the truck and took it out for a couple of "spins."

It drove pretty good. No clashing of gear no issue with shifting using my modern sensibility.

It was then I decided to start tearing down the truck for a restoration. Out comes the motor and tranny. Motor was replaced with a rebuilt unit. Transmission was next for restoration.

Open the top and pour out the fluid before beginning.

WHAT is this? Sawdust/wood cuttings all mixed with the oil.

No wonder it shifted so easily and drove so well.

Did you find oatmeal in the radiator fluid (another dust bowl fix)?

If you have a Mitchel overdrive, shift it into neutral and immediately down shift the transmission without double clutching and then shift the Mitchell back into low or high.

[nkaminar]

Ramman, Starting from 3rd gear:

1. Push the clutch pedal to the floor
2. Shift in to neutral
3. Let the clutch pedal out (all the way up)
4. Rev the engine to the rpm that 2nd gear will need (this is where experience is needed)
5. Push the clutch pedal to the floor again
6. Put the transmission in 2nd
7. Let out the clutch pedal

Same procedure for going from 2nd to 1st.

Unless you need the engine to help you slow down going down a grade, down shifting is not normally needed. In town driving you just pull up to a stop and shift from third into first (with the clutch pedal to the floor as normal).

[QUOTE=nkaminar;2270637]....."Unless you need the engine to help you slow down going down a grade, down shifting is not normally needed. ...." Uh ?? Don't know the geography of where you live Nkaminar but over we have many steep narrow slow hills and even if anticipated with full blast 3rd gear Yabber Dabber Do we need to drop down into second, and a couple of gradients within a mile of me are 33% 1st gearers!
