I have a 203 case,,,,,its leaking out of the rear shaft seal real bad,,,,its like parked in a slanted driveway,with the front of the truck facing the garadge,,,, (driveway slants down,from garadge to street) hasn been started since i bought it a few days ago, and even still it leaks all by itself ,,(btw its mated to a th350, but i dont think it matters any) i was eventually gonna do the 400 205 combo, but i wanted to at least drive it temporarily until i gather the set. Whats involved in fixing the leak? Is it worth it to fix the leak? Do i have to drop the pan? Also, if a dont have the know how or the tools to fix it,,, how much should i expect to pay a shop to do it? Thanks in advance all!
