considering swapping out my tranny bc i think it may be on its last legs and wants to take a big crap on me. anyways anyone know what are some compatible transmissions (5spd) for the 18rc? being compatible hence that it will directly bolt on,same mounts etc. If not, does anyone here know any good match ups for it? i heard the w58 is a good one....and btw besides fab work (crossmembers) what else will i need in order to complete the swap?
