I drained the gear oil on the transmission; where is the refill port?

Thanks so much

 

depending on wether or not it is a manual or automatic it depends but on a lot of auto tranny's the easiest thing to do is just get a funnell and pour it down the dipstick tube.

 

Above the axle, and a bit to the left, there is a 17mm plug, remove it and put in 3 qts of oil. USE ONLY ENGINE OIL .10w-30 10w-40 .. DO NOT use 80-90 w gear oil in honda trannies.
it will easier if you have a little pump to refill the tranny..

 

I suppose I should have payed attention to the thread starter before I posted... for once someone posts all the info we need before hand and I don't even bother to look...... Old habbits die hard I didn't expect to see it *L*

 

.. It's ok sir Nasty ,, it happens to all of us from time to time ,,,

 

why should you use motor oil instead of MTF on a honda?

 

What year?
Honda manual trannys were designed to use engine oil instead of GL-4 gear oil. Then in about 1996 or so Honda started selling their own gear oil, HONDA MTF. That stuff is compatible with the older Honda manual trans, but it's NOT compatible with other trannys which need GL-4 or GL-5.

 

its an 89

 

I don't know what that wants; don't know what year they began calling for engine oil. Got an owner's manual? If it says to use 10w-30 engine oil, then you will see a bit better results from Honda MTF. If it says to use GL-4 or GL-5 gear oil, then you have to use that.
