I never did get around to that, could someone please post the picture of where the bolt is? As I remember, it was supposed to be a 1/2", right? Any tips on how to refill it if I drain it?

Still, I am shocked and amazed that it takes 10/30 motor oil.. But it's right there in the owners manual! I still am not sure if it'd be better to just use honda manual transmission oil, a lot of conflicting information out there!!!

Supposing that it has not been checked in decades- I should check it/change it- right? I probably should... yeah?

 

See the attached. #41 is the "check and fill" bolt - metric size, I'd guess 14mm or 17mm?.

Below that is #39. That is the drain bolt. It has a 3/8 square hole. Take your 3/8 ratchet and stick it in the hole to remove and tighten.

 

Yes, it was designed to use 10w-30 engine oil. In 1993 Honda hadn't started selling "their own" MTF.

Honda MTF is better, and it's completely compatible with earlier transmissions that originally called for engine oil. (Any car that originally calls for GL-4 or GL-5 gear oil should not use it.)

But it's also a bunch more expensive. Does it work well using engine oil? Honda oil at 3-quarts per 30k miles really doesn't cost much per mile anyway.

 

Thank you! I know you posted that for me back in the day on here, but I could not find it.... I appreciate that very much. Is it going to be pretty much welded in there?? Good luck to me

 

That is good to know because I remember last year I spent all kinds of time reading about all kinds of debates about what to put in these transmissions.. I think I will go ahead and go with the honda mtf, but just out of curiosity, what makes it better? Does anyone actually know how it compares to motor oil in terms of the weight of it, the additives in it, etc? For some reason **** like that is interesting to me.

I completely lost all of the flexible funnel things I had bought for this .. So it is off to the aquarium store with $3 in my pocket, for me

 

I use a length of clear plastic hose from the hardware store, stuck on the end of a little funnel.

The weight (viscosity ranges at various temperatures) is about the same for 10w-30 engine oil, Honda MTF, and 75w-90 API gear oil. The differences are the additives.

Honda MTF has the EP additives, and it will have that strange smell like GL-5 gear oil. It also has friction-modifiers so it behaves differently for the high-pressure sliding contact of meshing gears. While also not being "too slippery" for your synchros to work. But other stuff (additives) in GL-5 oil are not there so don't use it in a car that actually calls for GL-4 or GL-5.
