Cooling fan turning on with the ignition is an air conditioning issue. Check that it is fully turned off. Otherwise look for a bad switch or relay. Check that AC compressor is not also running.
Compression test without a leak down test is an incomplete test. The leak down with full shop pressure bypassing the gauge set should tell where the leakage is. If exhaust valve is leaking that may need to get fixed. If intake engine will never run correct or smooth.  If piston-rings it can probably go for a while. 

There are pans on the bottom of the transmission. One for the ATF and one for the final drive or differential. Yes they have gaskets or seals.

Just got the van from the shop. Cooling fan runs from the moment ignition is turned on . I do recall it doing that before it went in, but it had been sitting. Any ideas?

Also, the van got a compression test - #1, #2, and #4 were 140# and #3 was 120#. Should I worry about that one low cylinder?

Finally, the auto tranny has a drip. Seems to come from the side if the transmission from a big panel that bolts on. Is there a seal under that which can be replaced, and what does it cover? I have never seen this but was told about it. Any ideas?

Thanks,

John the Gimp
