Default Trans Fluid Pumping Into Oil Pan

2004 Camry V6 LE 70,000 miles. well maintained.

The transmission fluid is disappearing but winds up in the oil pan.
No apparent leaks on floor.
Pumped one and a half bottles of trans fluid from trans to oil pan.

What can this be?
Expensive to fix?
How much?

Is this common?

I dont know about the others here but I am having trouble
understanding what you are saying..
Are you actually losing tranny fluid from the system over
time? You ARE checking the fluid level properly, arent you?

Any other symptoms?

Not over time, almost immediately.
The tran fluid is pumped into the engine and winds up in the oil pan.

Interesting....Normally there is no interface between tranny
fluid and the engine innards, as you know. On cars with
vacuum modulators, it was not too uncommon for the diaphragm to rupture and
the tranny oil would be sucked into
the vacuum system, ending up going down the intake manifold.

Please let us know when you find the answer to this one.

If the car has both an oil cooler and a transmission fluid cooler
the connections could have been switched...?

What a mess that would make! In seconds you would have
motor oil mixed with the ATF and it would be in the engine
and in the tranny.

If so, then why would the trans fluid be so low and the oil so high?

I only do oil changes so I never touch anything except the oil drain
plug and the filter. And I do know which stick is which and only add
trans fluid at the trans stick. Oil goes into the oil fill where it
has for the last six years.

What he was saying was that if you had a separate tranny cooler and a
separate oil cooler, those are set up to work
as closed loops, and the two fluids do not interface.. There
is no avenue for cross contamination, BUT

If you accidentally screwed up the connections, then the two
coolers would essentially be connected in series, and motor oil and atf
could (would) commingle. Both engine and tranny
would still receive fluid but it would be a mix of oil and atf.

I had said that I could think of no way the fluids could intermingle, but he
thought of one..It is a possibility, not
something that would normally happen. If you havent been
working under the car, and you havent had the vehicle to some
other shop somewhere, then it is highly unlikely...unless you
have a friend (or enemy) with a perverse sense of humor.

It wouldn't be the OP. It would have to be someone else who screwed up
the connectsions, but checking it shouldn't be too hard. Just follow
the lines and see where they go. He probably has no oil cooler in the
first place, right?

Agreed.

I haven't been here long enough to know if the poster is serious, but
he should still know that trans fluid is not nearly as slippery as oil
is and you can't run your engine with too much tran fluid in it.
Click and Clack just said last week that you can put a pint, or maybe
it was a quart, of almost anything in the gasoline, and the car won't
noitce, but there is some limit for the gas tank and the crankcase.
