How much gearbox oils is necessary?

Vehicle - 1994 Civic 5 Speed Manual

When changing the gearbox oil, the Honda owners manual indicates that 2
litres of gear box oil is necessary. However, to pour 2 litres of MTF into
the gearbox is virtually impossible unless you raise the vehicle in a manner
that forces the filler hole to be in the highest possible position. As soon
as the vehicle is lowered on a level ground, the fluid immediately begins to
spill out.

In addition, I made sure to that the old fluid was drained for over an hour
with the car raised so that the drain bolt was in the lowest possible
position.

If I go by the manual and fill the gearbox with MTF to the brim of the
filler hole, about 1.6 litres is all that is necessary.

Does anyone know what the correct amount is?

 

The manual may be correct. However, that doesn't mean you can drain all 2L
out. About 0.4 L remains trapped inside. Don't worry about it.

 

The 2 liter amount may be a dry-fill quantity, or maybe you're reading the
US qt. amount.

Correct procedure is:
1) Make sure the car is level (IMPORTANT!)
2) Pull the drain plug until oil stops running out (a minute or so)
3) Fill thru the filler hole until it runs out of the filler hole
4) Put plug back.

Entire thing shouldn't take more than 15 minutes, depending how long it
takes you to pump the new fluid back in.

Since I do my work on a sloping driveway, I use a carpenter's level to
level off the car.

 

Is it possible to drain most of the oil out of the gearbox without stripping
the gearbox by raising the vehicle in a certain manner?

 

Yes, the 2 litre is a dry fill amount. Is there any danger in filling the
gearbox with 2 litres even though it is not a dry fill?

 

Why do you insist on filling the full 2 L even after the answer to the
contrary? Unless you have done so already.

 

2.0 quarts for a dry fill, 1.8 quarts when doing normal service.

Mista Bone will have to answer the "danger" thing.

Dry fill is the amount to be added after a rebuild, when there is nothing
between the gears or trapped inside the synchros and bearings, nothing
coating the inside of the case, etc.

Fact is, the manual says 1.6L, not 2.0L. In any case, the amount is not
important. The LEVEL is. Fill it as specified until it runs out the hole,
then put the plug back. You're done and can stop worrying.

I never measure. I just pump it in until full. So I have NO idea how much
my Integra's tranny takes since it's been so long since I looked it up.

 

No. Some of the oil will always stick to the interior surfaces. On a cold
day, more will stick, on a hot day, less will stick. That's why you have to
go by the level, not the amount.


Change the fluid once a year and it will always be mostly fresh.
