Here is a somewhat inane question to ponder while waiting for summer to come.
Sedan gearboxes are tilted over to the drivers side, so if the filler hole is in the same place as a TR6 box, because TR6 boxes sit straight up, it would take more oil until the oil came level with the hole.
So are the holes in the same place in both boxes? If not, if I was to straighten the box in my 2500TC, which I have done, would I be under oiling it.

Re: Gearbox filler hole.
Helo Bernard,
I think it is fairly accademic, in practice. Yes you are right but saloon do not seem to suffer gearbox problems becau eof a lack of oil in them. bear in mind the designers leave some margin for loss of oil in service anyway?

Re: Gearbox filler hole.
When checking the oil level I always put the jack under the front left-hand wishbone, for easier access. This of course tilts the car a bit to the right, but I tell myself a little bit more for luck won't do any harm, might be beneficial, and will leak out anyway.
Re: Gearbox filler hole.
The gearbox must have a bit of a margin for level variation, as certain models have spacer blocks between the engine mountings and front cross member, and there are different heights of gearbox cross member - on some models it is directly mounted to the floor, and there are those with different lengths of spacer tubes to lower the cross member. I would argue these would affect the angle or plane of the gearbox. The level plug is in the same position irrespective of the type of gearbox, as the casing is more or less the same throughout the range, so as long as the level is near enough, I can't see it will affect the operation of the gearbox, unless exceptionally too high or equally too low.

Re: Gearbox filler hole.
I agree. Probably if you could look inside a running gearbox you would just see a frothing spray of oil all over the place. Those little plastic devices on garage counters illustrating oil being carried round the gears can't be realistic - you can't turn the handle at several thousand rpm.
