Evening all,

Bit of a mystery quiz this one ???
When the manual 2000 gearbox drain/fill plug is the same plug on the very bottom of the box,how in the h*ll do you fill it up once drained for an oil change while it is on the car still ??? its got me,and kiltyarse stumped!!!! :(

apart from turning the car upside down of course :p :laugh:
 
The fill plug is on the side of the box accessed through a large hole in the tunnel. Lift the carpet & soundproofing & you'll find the rubber bung. Can't remember which side offhand.
 
It's the same plug, but there's two of them. Pull up the carpet on the tunnel, (passenger side if I remember correctly) and there is a big rubber grommet, remove this and the filler plug is behind it. Should be filled with 20/50 engine oil.
 
THANKS BOTH!!! :p

I thought it was going to be simple, my haynes book only shows 1 plug on the bottom,unless I read the pic wrong,and it was on the side "doh!!" I didnt want to go taking all carpet back till I was sure :D I dont think oil will cure the sticky gears/rumble/squeal/high whistle etc, problem though,but it may make it last till I can replace his box with the "hopefully good" free spare he got hold of from a helpful fellow member in Reading! :p
 
Dave,
It didn`t make that same noise all the way home. It disappeared when I got to about 60 on the dual carriageway, then came back as I slowed for a roundabout. It went again at about 30 but was back before I got home!?!? ??? :p :angry: :laugh:
 
I found the elusive filler plug, not as it says in the Rover manual as being both the same plug! :p
Topped up the oil, it didn`t take very much. Took car for a drive, and guess what Dave, it still makes the same squeal, only a wee bit quieter. Changes through 1st and 2nd remain the same, so it`s as we reckoned and box out! I`m way past the stage of being cheesed off with this wee buggy..........I need a holiday! :angry:
 
It may well be worth replacing the oil rather than just topping up - when did garages ever follow service schedules if they could get away with it

New oil can make a big difference to rattles and whines, on my P4 the selector rattle at 70 stopped after changing the oil

True, my noisy 2000 TC gearbox became noticeably quieter after some fresh EP90. Additional transmission tunnel soundproofing did the rest of the job :D

If you want to postpone (certainly not avoid ) the rebuilt or replacement it won't harm to try an oil change :)
 
Nice one guys. I reckon I`ll try that before the weekend, but I doubt it will solve the selection problem I`m having, (and I don`t think it`s the rubber bush everyone keeps mentioning).
I`m past the stage of annoyance with having to pull over to the side of the road at roundabouts just `cos I can`t find a suitable gear to get round in! And folks say they`re over-engineered!!?

Cheers, Drew :p

Demitris.
You should have 20/50 in the gearbox, same as in the engine. I'd replace it as soon as you can if I were you as I think the EP90 is too thin.

Should that read EP90 is too THICK, or 20/50 is too THIN?

We discussed this on this forum a few months before and we concluded that EP90 will not harm a worn gearbox.
Actually the factory suggested it to cure cases of clutch drag.
In my case it reduced the noise from the worn bearings while the gearchange quality is excellent either hot of cold.
 
Gear oil can be thicker or thinner than engine oil, it depends on what the base oil is, what makes it different is the addition of sulpher which increases its' ability to withstand high pressures. Some synthetic gear oils are like water but rate at EP (extreem pressure) 140, this makes them very durable but with excellent lubrication properties.
All of that said, new high quality oil might help with quietening worn bearings and pitted gears but I think that it helping gear selection problems is unlikely as these are more probably down to wear in the selectors, baulk rings, synchro hubs, layshaft or linkage.
