Manual transmission drain plug..?

Where is the drain plug for the 5speed manual transmission the BA10? I could not find one that is low enough for draining the transmission. I found one towards the front on the passenger side but about 1/2 way up and there is one towards the rear on the same side about 1/2 way up. I tried opening one of those just to check the fluid, but I could not get it opened. I thought it needed a 3/8" ratchet and extension, but that is too large. So if you guys could let me know where the drain plug and fill plug is and how to get it open if I am looking at the right ones. Thank you very much and sorry if this is any easy thing, I couldnt figure it out.

Will

Here a fuzzy pic showing your level/fill plug #16 and washer #17. The drain plug and washer appear to be #21 and #20. The view shows the passenger side, with the rear of the transmission towards the left.

It's a 5/16" square drive that you need.



As for plug locations, I can't help you. My BA10 experience is limited.

What type of fluid do you recommend? My book says either 75/90 or manual transmission lubricant. What do you recommend and how much? Thank you.

Well, the "new official fluid recommendation" is 10W-30 motor oil for ALL manual gear boxes. We have AX-15's in out YJ's, and that's what I use. I've had really good results with that in ours.

IIRC, the original fluid recommendation for the BA10 was 75W-90 GL-4 spec gear oil. I think the manuals stated GL-5, but there was some chatter about that being a misprint, and the sulphur content of the GL-5 spec oil attacking the "yellow metal" syncros.

As for capacity, again my experience fails you on this on too. I'll check in the FAQ's & provide you with a link in just a minute.

The link that Alvy provided isn't the same one I have here, but the one he linked to is probably exactly what you need!

Go Alvy!

Here's some more info to help you out.
