How to check gear oil on 81 coaster?

[Minny]

Hey out there, hope everyone has had a good holiday season! An '81 coaster has recently come into my life and the gears a bit sticky, especially first. I recently broke first gear on my beloved corolla, so am scared I'm gunna do the same! 

I figured I'd check the gear oil but am not sure where to do that. Any ideas? 

Also does anyone know where to find an owners manual for this bus?

And another side note is it worth finding a second hand gearbox and getting the work done on my 91 corolla secs, 4afe engine. I'm so reluctant to give her to the scraps..

To check the gearbox oil, position the vehicle on a level surface both laterally and longitudinally. Then you have to go underneath and on the right side of the gearbox there is a drain plug at the bottom and a fill plug about 1/3 of the way up. I think it's a 19mm plug. SImply undo the "fill plug" and sticky your pinky finger inside and feel for the oil level. Usually if the oil is filled to the correct level a very slight amount should trickle out. That's ok. If it is below the lowest point of the fill hole then add fluid. For refilling oil in these instances I use a Tom Thumb fluid transfer pump. Easy to use and no mess.

If in your case the oil hasn't been replaced for an unknown period of time it would probably be a good time to drain and refill. I'm not sure what spec of oil it requires. You can do some research online to find this yourself.

All the best and Happy New Year.
