87 560 auto trans leaks at the rear after driving or idleing for a while. We took it for a test ride after doing so body work on a rusted floor. My buddy just bought the car (cheap $500.00) body is good but drivers floor rusted out. back to the leak we went about 8 miles and saw trans fluid behind.we shut down right away and hooked it home. today we put it up on stands ran it. Put more fluid in trans and looked for a leak. when we stopped and had it towed fluid was just pouring out. now after runnig for a while it was just starting to drip.Any ideas

I had the same proublems in the past I think its the Rear Pump seal
before spending a lot of money try some Transmissing sealer run it
200 / 300 miles and let it set a few days the leak may stop that worked
fine for me.The O Ring gets hard and starts to leak. May Work for you
