Default 95 4EOD tranny gasket- use a sealant? - 04-17-2007 , 04:19 PM






Hi, back again concerning my 1995 Bronco XLT 5.8l 4EOD. I bought the
filter kit today (Purolator) and it comes with a gasket. Not only
with a gasket, but with a piece of paper stating the gasket should be
used for 1989-1995 vehicles only. It further states for 1996 and up
vehicles, reuse the existing gasket. So, I figure I have to replace
the gasket.

My question is whether to use a gasket sealant or not. And if I do,
which sealant to use, and how to apply it. Is there some risk of the
sealant seeping into the trans and gunking up something? The new
gasket is of a rubber or synthetic type material. It is not cork.

Thanks,
John

I have another question. I have to turn the motor by hand to get to
the torque converter drain bolt. The bolt on the front of the
crankshaft (harmonic balancer?) is bigger than what I have. The
biggest socket I have is either a 19mm or ¾in. Too small. Anyone one
know the size of the socket needed? I was planning on using my
regular ratchet, and maybe adding some pipe to it for leverage. How
hard is this thing to turn, anyway?

Thanks again,
John

Not. If you have trouble keeping the gasket in place, either get
threaded studs the size of the bolts and screw them in loosely so they
can be removed after you install the pan, or tie the gasket to the pan
with #36 or finer wire (an individual strand from #18 zip cord works)
through the bolt holes. The wire can either be left in place or cut
and pulled out. I usually just flatten the gasket the day before I
install it.

The AAMCO located at 8825 N. Black Canyon Highway, Phoenix, AZ (602)
997-6289, used sealer and ruined my transmission. The dealer found
bits of sealer in the valve body and elsewhere and said the
transmisison was damaged beyond repair. Naturally I highly recommend
this particular AAMCO.

That's one way of condemning a transmission. Since all of
the fluid has to pass through the filter to get from the pan
into the transmission, I fail to see how the sealer could
get into the valve body. If that were true, all the crap
that normally collects in the pan from the clutch plates and
wearing parts would destroy a trans in a few miles. This
technique is used by the unscrupulous to sell the unknowing
a new trans while blaming it in someone else rather than
finding out what happened. It just made the dealers life
easier by making AMMCO a scapgoat when they used the sealer.
Proiperly used, the sealer is both harmless and, usually,
unnecessary. It just makes the pan more difficult to remove
next time around and makes sure you cannot reuse a reuseable
gasket. I suspect you got screwed by AAMCO as usual and the
dealer.
I also don't see how sealant could have gotten past the filter or
screen, and I suspect it was used in other areas as well. But I doubt
the dealer was dishonest because the car ran fine after they replaced
the transmission and rebuilt the engine (AAMCO admitted to running it
without coolant), and AAMCO paid them for all the work. On the other
hand AAMCO could never get the transmission to go more than 200 miles
between breakdowns, and I'm sure they lied to me when they claimed
they had worked on my particular type of transmission several times
previously (An AMC/Renault model that had that been on the U.S. market
for only a year?), and the dealer mentioned that some AAMCO mechanics
had visited several weeks earlier to get information about the
transmission.
