Hi,

Today I went to change the fluid in the transmission and diff of my 94 V6
Camry (3VZ engine with iron block). The handbook with the car specifies that
this model has a separate fluid supply for each, and in previous fluid
changes I have done, it has always behaved that way.

This time I drained both hot, leaving them until the drips had just about
ceased while I had some lunch. I replaced both drain plugs, took out the
diff fill plug, and got out from under to fill the trans through the
dipstick tube. This is always slow as I don't like to slip and make a mess
below the dipstick.

Once I thought I had replaced about 3 litres or so, I next went to fill the
diff. To my surprise there was about 1/2 cup of Dexron on the ground
beneath, with more coming out the filler hole at a fast drip. It did not
slow at all in the next 5-10 minutes. I first thought maybe this was
draining off the gear teeth or something, but that makes no sense as
draining had previously all but ceased from the lower plug. Thinking the
thing was trying to fool me into driving off with an empty diff housing, I
tried filling it anyway, but everything I squirted in ran straight back out.

It can only mean a leak from the trans to the diff casing, below the level
of the trans fluid. And yet, a normal amount drained out of both, about
3-3.5 L from the trans, and about 0.7-0.8 L from the diff.

Anyone seen this happen?

Thanks

Geoff

Other Camry posts mentioned a seal can leak between the transmission
and the differential. Costs about $600 to fix at the dealer.

When I cleaned, regreased, and rebooted my CV joints a couple of years ago, on
my 94 v6, I drained the diff fluid so it wouldn't leak out when I pulled the
shafts out. When I finished a few days later and went to refill the diff case,
I found it would only hold about 1/3 of a quart. After starting the engine and
checking the tranny fluid, it was about a quart low.

Even though they call them separate compartments, I'm sure there is an opening
between them, so gears won't be ruined if people forget to refill the diff.
