I searched the site on the matter and have come up dead center on wether to do it or not. I just want to ask if it is worth it do you go transgo or b&m? My tranny already has a leak, but still feels good. I figure it may be a gasket, she only has 89k on the clock and shes bone stock except for msd wires, air foil, fan switch. also is it possible that one can do it yourself with descent mechanic skills. Thanks in advance
