You should see a casting date on the Transmission case. Mine is on the drivers side near the Top. Mine was cast 2-13-31.
Since yours has the threaded style shifter cap it is the later one. I'm not sure when they changed. I do know the shifter cap that is held in by the Pins is considered the early AA Trans. I believe they came out at the very end of 1929 and only in AA Trucks. They were a common Dealer retrofit into Model A's especially in the Pickups. They are the Beefier Truck Transmission, very Heavy Duty. They made them well into the 1950's the gears that is. The cases changed often.

It's not a 32 trans, the 32 and later have no provision for the clutch
and brake pedals.

I found a little cast tag that reads...7--3.. could that be July of 33, or is that the wrong tag? There is a mark next to it that looks a little like a @ but about 5/8" diameter..

Thanks for the picture....nothing there on my casing though. I see at the bottom on your case is the "AA 7000"...I found that on the passenger side of my case, about 1/2 way down, with the number "4" below it......

Still looking!

It looks like he's got the older AA trans with the 3 speeds + hi/lo foot lever. Maybe if he puts it in high and leaves in there.

There is no foot lever..but I've seen pictures...but where would the foot lever have connected to the transmission? Did they use the PTO access? The battery is right there on the driver side...so no room now....

Thanks!

There would be a HI-LO tranny in place of the intermediate shaft, right behind the main tranny.

OK, he mentioned the PTO access, so I assumed he had a truck with a 4 speed.

You remember the motor mount with the 5/16 plate on top and no bolts to the flywheel housing?

New parts came today and the mounts have been replaced and the bolts installed...

The bottom bolt was just missing, the top bolt was broken almost flush with the case so I Dremeled a groove in the stub and took it out with a screwdriver....easier said than done but it is done..finally...

Notice the gap at the bottom of the motor mount in the first picture. That shows why original mounts are better than float a motor mounts.

It looks like at least one of the bell housing bolts has a rounded head, rather than a flat head. It might have been switch with another engine bolt of the same size. The side water inlet has rounded head bolts, and the timing cover does also.

The 4-speed transmission rear bearing retainer should look like the one in the photo below. This is for the AA chassis. The A chassis used the same retainer except it was about 1/8" less in thickness.

The bearing retainer shown in the 1955cj5 photos is not the A chassis part. Also, there was not support used as shown in one of the 1955cj5 photos.

Vince has information and pictures of the parts to install the
4-speed in the Model A on his web site. http://www.fordgarage.com/pages/aafourspeedachassis.htm

Thanks for the photos and information....

Right now the rear bearing retainer is a mystery...I don't thing it looks like the AA retainer but I'll go look more closely....

And today I think the support that is hanging on the crossmember will come out.....

There is pressure on it so it is supporting weight....I just hope the transmission does not rest on the brake cross shaft once the support is removed.....

I finally found the casting date, under a layer of grime! 2-12-31....the day before yours! But its on the shift tower and not on the case....and so far there isn't one on the case itself..different foundry?

Been mulling changing back to a 3-speed....were there different torque tube lengths? Measured a 1930 today and it was 49 3/16 from the back edge of the clam shell to the front of the flange at the differential.....mine measured 49/1/2"....does that sound right, or has the tube been altered?
