Holes in back of transmission case...

[329s]

I just noticed something and I should know the answer to but do not know. I have several transmissions and all but two of them have the four holes that accept the throw-out bearing assembly tube as they should.

What are the two transmissions which do not have the four holes used for?

Just how was the throw-out bearing assembly tube attached?

They are the later transmissions with the thick bearing flanges on each end.

The ones without the four holes in front were on the early cars with a multi-disk clutch. They did not use a front bearing retainer that the later throw-out bearing slid on. The early throw out bearing mounted on the clutch pack and rotated with it. The grease fitting was actually inserted into the throw-out bearing itself.

Thank you guys...further inspection with the others, I see the differences on the inside also with the revised bosses which removed the brass washers.
