75-76 Aluminum 833 4 speed Overdrive trans questions ?

From the factory, the hole is slightly loose. The pin thus, rides in oil. which allows it to bang around and eventually the hole goes oval. This allows the cluster, under load, to move away from the input gear, decreasing the gear-tooth engagement.This is said to reduce the torque-load rating, which makes sense. I cannot speak to that.
The sloppy fit is said to reduce gear-rattle.
I thought to myself that this was not a good idea, so on one of mine, I loctited the pin in. But you guessed it, at tear-down the loc-tite was gone..... so I bit the bullet and bushed it. It didn't cost that much.
