			'''Aidan on driving technique to prolong life of box'''

			Remember folks the steering wheel is where your hands should be except at the point of changing gear, don't drive with your hand on the gearstick (in any vehicle) as even the slightest pressure or movement can cause wear in parts that want to be in their natural resting place, eventually that wear can cause selection issues

New owners - check your gearbox oil level, whateber you have been told about previous servicing!

It has come to our notice over several years, that many gearbox problems and indeed, total gearbox failures are caused not by simple wear and tear, but by a simple lack of oil.

These vehicles are now old, and gearboxes can slowly leak oil. Very often this is because the castings (particularly early ones) corrode, and the sections ease apart, allowing slow but consistent weeping/leaking.

many garages do not think about (nor are paid to) check the gearbox oil level. It is not a 5 minute job, indeed, without draining and refilling, there is no easy way to ''accurately'' determine the actual level. It may be possible to estimate it without dropping and refreshing the oil.

'''NB.'' Additionally, it is soemtimes not too easy to remove the oil filler plug. Remember, do not remove the drain plug until the filler plug has been loosened

So, if you have just acquired a T25...

then it is '''a very good idea''' to get a garage or T25 savvy person to '''make sure your gerabox has actually got some oil in it.'''

T25 gearboxes are becoming expensive, some parts are now difficult or impossible to buy new, or are very expensive. A typical rebuild could cost from £750 to £1500, and requires specialist knowledge and tooling.
