Are these picture clear enough to determine if this is a early 28 transmission , Its a 3 speed , does not have the multi disc cluch. It is a February 28 truck was told it could be a truck transmission Thanks Biil

Need a picture of the reverse idler shaft end to tell for sure. The early 28 had a collar around the reverse idler shaft. Rod

Looks like conventional clutch to me. What is the diameter of the hole in the clutch shaft?
Shift tower looks early.

I haven't seen the hex drain and fill plugs like you have.
The shift top is the early one for cars using the left hand parking brake.

I sent these pictures to a model a parts place, He said he thinks this is a AA transmission something to due with the square shape on the bell housing or where the bell housing meets the transmission. Said he wasn't sure if they could rebuild it or not would get up with me Wednesday when the transmission guy is in. I need to get this going asap due to the fact we carry our members on in for their last ride and we have a older member that is barley holding on. I can take more pictures or next day it to someone who can rebuild it for us. I need to make sure what it is and be sure they can rebuild it Thanks Billy

There are several of people who likely could rebuild it. It does not have the multiple disc clutch and bell housing. So it is the later (after Nov 1928) transmission. The 3 speed was the same as the car until the introduction of the AA 4 speed. The clutch would have been 9 3/4" instead of 9". I am unaware of anything that would make it harder to rebuild than the car 3 speed. These are relatively simple transmissions so very likely you could rebuild it yourself with a little research and some patience. Rod

Here is an early 28 transmission. Doesn't look like what you posted. First photo shows the end of the multi disc stack of plates and the extension of the flywheel.

If I order a rebuilt transmission from the parts place will it look just like this one. They want to keep this as close to original, I have to do something pretty quick, Does it appear to be a standard bell housing. It does have the early starter switch with terminal on the end im so confused please help me sort this out Thanks Billy

Here is a standard transmission. Too bad you don't live close the Houston,TX I could sell you this newly rebuilt one I replaced with a multi-disc! You might want to take off the early switch and check that it still has the raised contact under it. BTW does it have the 1/2 inch shaft starter? I'd love to trade you for a 5/8 shaft starter! Post a picture of the bendix on the end of it. Why do you think it needs a rebuilt transmission?

2 teeth missing on 2nd gear, Im totally lost early starter, left hand brake, but has the ribbed petals and no multi disc clutch

What is there to be confused about? I have seen the early transmission top and left hand brake handle on AA's as late as January of 1929. I think you have yourself convinced it is an early 28 by looking at only 2 pieces. Also changing the clutch, flywheel and transmission was not uncommon if the owner had trouble with the clutch at some point and wanted to update to a clutch that was cheaper to fix the next time. Just my thoughts. Rod

I'll sell you a good 2nd gear for $25 including shipping. These transmission are very easy to take apart. It can be apart and back together in 15 minutes. You can drop the transmission in an hour.

Early starter will work on later flywheel but later starter won't work on early flywheel. My early 28 has ribbed petals probably replacements for the smooth ones sometime in the last 85 years. Both are welded on. Many multi-disc clutches were replaced when the flywheels wore out due to the clutch splines. There is a much bigger supply of later flywheels and clutches. BTW everything from the flywheel, pedals,bell housing to the transmission case and some of the gears must be changed to go from multi-disc to single disc clutch.
