Good evening,

I've been looking to get my manual 5 speed transmission oil swapped out with some fresh
new oil. Well 2/3rd's new by the rule of thumb.

To be honest the illustration and translated english I have in my owners manual makes no
sense.

What I would need to know is where are the locations for the drain and filler bolts. The
special fluid grade required. I'm 3 hours away from a hyundai dealership/service
counter. Would like to avoid the mileage. Also if theirs anything else required in the
process such as special washers/gasket replacements while doing the job.

Thanks,
--

There is no filter on the manual transmission. The fluid is typical 70w-90
or 75w-90 gear oil (check your owner's manual for exact specifications).
Simply remove the 24mm bolt in the bottom of the transmission to drain.
To install the new fluid, you'll need to remove the 17mm bolt in the front
of the transmission. But since the hole is small and horizontal, you'll
probably need to construct some sort of device to get the oil from the
bottle into the bolt hole. With the car on level ground, once the oil
begins running out the hole, the transmission is at the proper level.

Its a pain using an manual oil gun to replace it because the oil is so
thick. I usually just set up a siphon with the oil container on top of
engine and a clear "plastic" hose down into hole. Takes a while but I
usually do something else while its happening. Worthwhile putting a
container underneath so when you forget it the overflow doesnt go on floor!

I'm really surprised that you said this, as the required oil is not
"typical". The Hyundai transmission requires a GL-4 oil, which is not
always available off the shelf at auto parts stores. Most common oils
are GL-5 (or marked as GL-4/GL-5), but those will damage the
synchronizers if used in a Hyundai tranny. Personally, I use Redline
MT-90 synthetic in mine.

FWIW, the new cars are all spec'd to use 75W-85 oil, which is even
harder to find. I doubt that it makes much, if any difference, as long
as you use a GL-4 oil.

I used a long funnel with a piece of plastic tubing attached. Worked
like a charm.

Useful information, I will have a go at changing mine in a 2001
Elantra, for the record do ever check the transmission oil level in
between changes.

I've not experienced this damage, but we have the factory 75W-85 (Hyudai
says this is okay to replace the -90 oil) in quarts, and this is what we
install. Bottom line, sticking with the owner's manual is always the best
recommendation. Thanks for pointing this out, Brian.

Is the Redline a GL-4 oil?

No. Unless there's a leak, which I would see on the garage floor,
there's nowhere for the oil to go, so the level doesn't change.

Yes, that's why I use it. They also make MTL, which is a slightly
lighter weight GL-4 oil.
