(G) Transmission Oil Checking / Change

Further to my previous post re the gear change being somewhat difficult at times, i've been trying to undo the filler plug to check the level of the transmission oil.

Got the correct 12mm bit for my socket set but there's no budging. Sprayed with WD-40 - still nothing. Tried using the centre part of an axle stand to add extra leverage but still no change.

Anyone got any ideas?

Also, when checking the drain plug, i noticed there was a little oil around what looks like a gaiter behind the drain plug - photo attached. I'm guessing this isn't good so any thoughts/advice welcome.

That looks like a leaky gaiter to me. Top it up rather urgently, even if you can't get the drain plug out.

Try a can of plus gas A or other specialist thread releasing compound. Although it is messy (afterwards) you can make a coffer dam with blue tack and leave a puddle of plus gas overnight.

Tap the end of the socket lever with a soft faced hammer, dont welli it. it should not really be too tight.

Was the leaking oil on the drive shaft gaiter?

P.S. dont drive it until you get the filler plug out and get it back to the correct level, a seized box is not repairable

Its a taper seat plug so will need a good bit of a heave to get it out, just keep a bit of pressure on it for five minutes.

Finally managed to get the filler plug to budge, after applying force for a while.

Topped up with about half a litre of transmission oil so there must have been a fair amount in there.

At least i now know it is full (for the time being) and that i can check and top up at will.

Need to get the leak on the gaiter fixed now.....

Drive for 100 miles and recheck the level, just to make sure. Gear oil is thick stuff and takes time to get down into the box properly.
