can the bearing retainer be swapped over from a od to a four speed and the non od 833 be used in its place? my trans locked in 2nd now and is flat worn out

Err... just add an adapter ring to make-up the size difference.

If you are lucky enough to find a 1975-1976 A-body or 1976-1980 F body with a 3 speed, the unit will have an input bearing retainer that will bolt to the 833 and fit the OD bell...pretty much a tough to find item, and Wildcat/Brewers want some $$$ for one if in stock.

any one got one?

Isn't the overdrive bearing retainer bigger than the regular 4 speed retainer? I put up an ad on FABO last year and was able to trade a guy mine for an OD retainer. Put up an ad over there and see what you can get.

Yes but there are things that have to happen:

1) The A-833OD uses a larger diameter bearing retainer...but the input bearing is the large 308 style bearing that you would find in the 440/6pak and hemi 18 spline boxes...
2) The standard A-833 and most 3 spds, use the smaller 307 input bearing so their retainer bolt pattern is much smaller...

So the choices are:

Sleeve like Doc has shown.

1975+ A-230 bearing retainer (small bearing bolt pattern with the 5.125" retainer diameter).
