A-833 OD in Aspen... not the right one?

Then they are not OD transmissions unless the bearing retainers have been changed or turned down. The only size bearing retainer the OD came with was 5.125".

Read here about the 4 speed overdrive transmissions.

You are right, that is what made it so hard to figure out. At first I thought they were BB A Body trans, due to the size of the retainer, and everything I read. But when you pull the side cover off, they are very nicely preserved O/D units.

Just to confirm, I wrote down all the numbers, on both units, and emailed them to Jamie at Passon. He gave me the O/D news. It wasn't what I was wanting to hear, but that is what they are.

I just need to get off my rear, get some pictures taken and get them listed on here. I am not going to use them.
