Hello all,first time on this forum. I bought a bx22 with a cracked housing on the transmission. I am going to attempt to swap it out. It looks like I'm going to get the entire axle set up when I take it out, I see how to take the pto and drive shaft out. I"m wondering what I'm going to run into on the top of the tranny, under the seat that I can't see. Has anyone out there done one of these before? Any tips where I should look to buy the replacement besides my local dealer? any help would be great. thanks in vermont
