I have a 1996 Taurus w/3.0L OHV engine> I bought this car with
problems. After a test drive around the block a couple of times I
pulled the car back into my shop when I opened the hood I was getting
overflow from the cooling system with transmission fluid in it. I had
just filled the cooling system & was testing it out. It seems the
transmission oil cooler sprung a leak.
I'm in the process of putting in a new radiator. After the radiator
install I want to drain & change the trans fluid. I don't think much
if any coolant got into it. The cooling system had mostly water in it
because it needed flushing. the trans fluid is pinkish rather than
red. I plan on draining the transmission pan then fill the trans
fluid, drive around the block a couple of times then drain it & refill
again.

Any ideas/experiences with this?
Is there a way to drain the torque converter to do a better job on
this?

TIA
