[net.auto.tech] Changing Transmission Oil in Honda Civic

dss00@amdahl.UUCP (dss00) (12/13/85)

I recently changed the transmission oil in my Honda Civic (Sedan)
1500 cc engine (1984). Draining the oil was no problem, but it took
for ever to fill it back. They have provided a hole on the side
as against on the top to fill oil. I attatched a plastic tube to a
funnel, pushed the open end of the tube in the filling hole, and
poured the oil in the funnel. It would take a long time for the oil
in the funnel to go down in the tranny as if something was blocking
it at the other end. It took me about 10 minutes to get the approx
three quarts the transmission needs in it.

I would appreciate suggestions for doing it better the next time
around.

Also, I am planning to switch to Mobil-1 for the engine. The engine
has about 21,000 miles on it. Is it too late to switch (I have read
some people say that the right time to switch is immediately after
break in period i.e. about 6000 to 8000 miles. Do I have too much
deposits in my engine already to cause any problems?

Thanks in advance.

There is a tool designed to alleviate this problem.  It is a suction pump
device that looks like an overgrown bicycle tire pump, a single piston
in a cylinder with a handle and plastic tubing for feed and delivery.
You simply suck up a load of fluid and discharge it into the xmission box.
Nothing to it, I do it all the time.  I bought mine quite a few years ago,
and I can't remember where I bought it, but they should be available at 
a decent auto parts supply house.

Don't complain! I think the '84 Civic is one of the easiest cars I've
ever changed gear oil on. Everything is far more accessible than any
rear drive car and most front-drives. But if you want the job to go
faster, use a slightly smaller tube on your funnel, since the filler
hole is the only air vent (I assume) on the transmission. Of course,
if you use too small a tube it will take a long time to fill for another
reason. My advice would be to use the ten minutes to do some other main-
tenance.

A switch to Mobil-1 should be fine even up to about 50k miles.
I have used it in engines of various ages with no problems.

One word of warning though, don't put it in the transmission.
I put Penzoil PZL (Do they still make it?  I haven't seen it in years...)
in my transmission at the 50k change.  The car acted like the syncros
were going out.  Changed back to rot-gut 10w40 and all was well again.
Seems that the super slippery oils don't leave enough friction for
the sycro rings to work ...  (It is mighty hard to resist the temptation
to put the same 10w40 in both engine and tranny, the directions
don't say anything about the transmission being special - just says to
use 10w40 engine oil.  But I have only put plain oil in my transmission
(no super slippery stuff) since the fiasco at 50k miles.  It still
works like when it was new.)
