4 speed ka-booom !

If it's an A833, you don't want another one.The cage is taking up valuable space, so whatever load is passing through it is being carried by fewer rollers at any given moment.It has an advantage, but I wouldn't use one here. Except maybe in a low-power situation.
Keep in mind that any time torque is passing into the cluster gear, that cluster gear is trying to force the mainshaft away from itself. So that bearing is taking a load.It's probably worst in 2nd or third, and least in direct.

To be sure, there are other ways of assembling these automotive trannys, but of course, I like MY way bestest.
I share what I have learned, cuz it's the right thing to do. Can you imagine a world, where the first man, Adam, never shared what he had learned, and every generation after him had to learn it on their own? There might not even be a world, if he hadna learned how to procreate!
