Hey guys,

I've just got a 5 liter Mobil 1 for my 90 Accord :))
It's going to rock when I put it in on saturday...

The question I have for you is what kind of oil would be best for the transmission...
manual asks for SE or SF grade motor oil for transmission which is virtually nonexistent.
I think the previous owner of my honda never changed the gear oil so it's the first time...

Anyway I went to walmart today and the guy was really puzzled at my question for alternative to SE or SF gear oil...

So please let me know if you have any suggestions in this regard...

Thanks

Dave

Regular 10w-30 engine is all you need.

Would there be a better alternative to that?
Like I've noticed some special gear oils in walmart... are those any good or not or what's the difference?

The gear oils are not for Honda manual transmissions.

Get a snythetic 10W-30 if you can. Synthetics are just wonderful fluids, I dunno why I'm so crazy over them other than their "perfect" properties for their applications.

I have an 91 LX with manual transmission. Can somebody tell were should I look for filler and draining plug on this accord? and what is refill capacity? I plan on using Mobil 1 10w-30 as a replacement fluid. i have 193k miles on the car.

Thanks for your help.

Both plugs are on the side of the tranny - passenger side
Fill capacity is about 2 qts - easy way is to fill until fluid begins to drip from the fill plug - level should be at the bottom of the fill hole

*Always remove the fill before the drain*

Hey guys, thanks for awsome replies,

I've put in regular castrol 10W -30 into transmission (mainly because I read somewhere that synthetic slips in transmission)

Although the old oil was shiny yellow and my mechanic told me that I wouldn't feel the difference it was so much better with the new oil...
just perfect...

Is there a washer for the drain-plug? If there is one, will the engine oil drain-plug washer do the job? Or do I need to make a trip to Honda parts before I open the drain plug? Thanks for the help.

As much as I remember the guy reused all the stuff for the transmission oil change, however I would ask for a second opinion before opening the plug. (and by the way when you open it it spurts at you like crazy so be careful)

One more question. I looked at passenger side of the axle and it seems like there may be two filler plugs within few inches of each other. One is few inches above the other. Which one should I open for the filler / level check?

The drain plug seems to be just 6" above ground. Am, I correct? Thanks for help again.

The trans drain plug uses a larger washer than the oil drain plug. Its recommend you replace it, but I have never had a problem with a trans dripping.

The higher plug is the fill plug - should be 17mm - always open the top first. The drain plug is at the bottom, on the side - use a 3/8" ratchet to remove it. If its a magnetic plug wipe it off before installing.

Also its not a bad idea to flush 1qt while both plugs are out. I usually flush manuals until clean fluid comes out.

It's always a good idea to replace the crush washers on the tranny or oil pan drain plugs, I've seen two burnt trannies caused by a slow drip from the drain plug running the tranny low and countless "oil leaks" caused by a reused crush washer. It's a .59 cent part that can save you quite a bit of money.
Also the 10w-30 is a good choice, but if you keep up on your maintenance schedule synthetic is a waste of money.

Thanks for the input. It seems like I may have two oil filler plugs. They are within a inch or so of each other. The top will take 3/8" ratchet (just like the drain plug at the bottom), the one below will take 1/2" ratchet.

If I am not misktaken from the discussion that the actual oil filler plug is the one with 1/2" square. This is 91 honda accord LX.

Good advice on flush... I guess I will also use the Dino oil and use one quart for flush. Yesterday, I had the axle job done on the passenger side axle and some of the tranny oil leaked upon the removal of the axle. I plan to do the job on the weekend. Thanks again.

The fill plug should be a 17mm, possibly it was lost & replaced with some thing else.
