Obviously I never posted pics. I'm just confused on that matter. I have taken my J-type m46 apart. removed the OD with a slide hammer. hopefully this didn't destroy my OD unit. Under further inspection I need a different layshaft. However, there is a store in Atlanta with a nice iron case gearbox with no overdrive attached for a reasonable price with shipping. Wondering if my aluminum case J type will fit on the earlier iron box without issues. Also would you suggest rebuilding my OD unit if the oil looked terrible and was full of metal flakes? I know there are a few filters in there but the fluid was pretty metallic. And the magnetic drain plug was full of shavings and chunks.

I do intend to continue on with rebuilding mine just as an experiment. but at this point I really want to drive my car again. Also, I figure with the amount of noise my P-type made it wouldn't be fixable without getting all new internals, even the gear surfaces look worn out. I wouldn't want to even rob the layshaft.

Any advice is much appreciated, thanks in advance.
