Location of gearbox/transmission filling area

[danb187]

Hi...new to this site but I've had a 63 Midget with a bugeye hood for several years. I only have a manual for a bugeye that describes the filler hole as being under the drivers floormat. Can someone advise where the location is on a midget...because it's not under the mat... Thanks, Dan

Left side of the transmission tunnel towards the front there is an oblong rubber plug. Pull this out and you can reach the filler plug for the transmission. It's a bit of a PITA to get to, but is accessible. You'll need to pull up the carpet that is on the tunnel

You should have an access hole under the trans tunnel on the upper, left side (Driver's side for US models).

If you lift the carpet over the front part of the trans tunnel, you should see a rectangular, rubber plug.

Remove the plug and things should look like this.

(use motor oil for the trans.....not gear oil)

I found the simplest way to fill a Spridget gear box was take the three 7/16 bolts out of the shifter plate. Remove the shifter and fill with one quart of 30w non detergent engine oil. Be carful with the detent plunger not dropping down into gearbox. You can remove that easily too.

I can answer the first part of your question easily. The location of the gearbox is directly aft of the engine, with the bell housing and clutch in between.

Once you do get the plug open, then you have to open the fill bolt. Make sure you have a long enough extension on your socket wrench. The standard 2" extension for a 3/8 drive is just long enough for the ratchet to catch on the hood release knob and break it. Ask me how I found this out.

You also want to use a funnel with an extension when you fill, or a pump type device as the angle is a bit awkward for a standard funnel.

Thanks for all the advice. I found the rubber plug under the carpet and added almost a quart of oil to a very thirsty gearbox ��....Dan

Been many a gearbox ruined by owners not as attentive as you! They use a scroll seal at the front and the oil does go away!

But the oil from the scroll seal is from the engine not the tranny.

Scroll seal on the tranny as well, Jack. The British loved scroll seal's. I wonder if BP didn't have a plant in the engineering college's!

Ok, but the one on the tranny is not the leaker, in fact I have never seen one that shows any indication of leakeing. Just lucky maybe.

Well you're right Jack but if you don't check your gearcase regularly the oil goes away and I can't figure out where else it could be going. I've got 2 boxes here that were both done in by being run dry it appears [PO].

The rear seal i should expect it is a cloth cotton like seal and the oil sloshes to it and is always wet it seems. Wonder why the tunnel does not rust, hehe oil from the rear seal.
