Default Re: A vs AA Transmission

And one more thing.....

Anyone know what the oil capacity is for the AA transmission?

I've searched and searched and haven't found anything...

I've read that the A is one pint..

I've put two quarts in the AA and it's still not quite full, and now I'm out of oil but it's nearly full as I can see it through the filler...

It sure shifts better with te 600w and it's quieter too...

I found the answer....I had to sign up over at thee aa-ford forum so I could search..

The AA transmission holds 6 pints...3 quarts.....considerably more than the A transmission.....

I have solved the shifting problem. The pressure plate was out of adjustment and as a result the clutch linkage was way out of whack...

Shifts fine now...

I thought I'd post a couple of pictures of the AA and A bell housings side by side....about 1 7/8" height difference...

I learned a couple more things about the AA vs the A transmission...at least on my installation..

Mine has a 32 or 33 BB rear transmission bearing retainer...BB-5089-A..i found one on ebay...

And the bolt spacing on the u-joint clamshell is 2 7/8" vs the 2 3/4" spacing on the A clamshell with evenly spaced holes...

Don't know..it's in there..I didn't put it there....the upper ears have been broken off...

Remember I have a 4-speed, which must be AA because the pedals still mount on the transmission case...

I looked at a fellow's 30 ccpu the other day, he has a 4 speed...the rear bearing retainer is very different...

But this is a picture of mine...

Default Re: A vs AA Transmission

I recently bought a copy of the Service Bulletins. While paging through I noticed this subtle difference between the 4-speed and 3-speed on page 509...

And sure enough my old AA clutch shaft was offset, but the replacement was an A shaft and so though most of my shifting problems with the 4-speed had been resolved with new bearings, clutch disc and pressure plate, this just created a new problem....

AA 4-speed shaft on the right...

4-speed is gone now and the 3-speed works great.

He might be in the market for your AA tranny if you are thinking about selling.
