Getting ready to rebuild my A833 OD and I'm hoping the experts can lend me some advice..I've got an A833 OD truck tranny, aluminum case, side cover and tail housing. I am needing to rebuild it do to poor shifting and loud whining/humming when idling. I spoke brewers performance and the can get me an early model cast iron truck case for a good price. So my questions are these: 1-can I use the cast iron case and swap the guts of my aluminum tyranny into it 2-would I use the same rebuild kit for my aluminum tyranny or would I need a different kit 3- do I have to/need to get the cast iron side cover and tail piece also...thanks in advance guys :-) this is gonna be my first project since my accident so hopefully I can handle it!
