Hi all,

Can anyone tell me how often the gearbox oil and diff oils should be changed?

Thanks,

Dipesh

every 2 yeara says the haynes manual! but if you dont know whens it been changed; that for me is a good enough reason to change it yourself!

very very very easy to do both!

the gearbox fluid is not only cheap but as said, easy to do. with a torx bit, locate the FILLER which belive is on the drivers side on the sideo f the gbox. always unsrew this before the drain as they are quite stiff; you dont want ot drain all the fluid and then find out you cant open the filler! once the filler is open, the DRAIN PLUG is at the btm of the box. you'll need an old AUTO TRANY FLUID bottle, as they have nozzles to feed the new fluid in!

with the diff, much the same case, though somewhat easier! the filler plug first, which is the top of the two bolts you'll see on the case. once open, then open the drain plug. dependant on whehter its a LSD or not depends on what fluid needs to go in there! DONT WHATEVER YOU DO put the wrong fluid in a LSD!!!

to do the gear box you need a 17mm hex key.

better to buy that as they only cost a few quid and then your sortedfor next time you need it.

Good idea to buy a oil suction hand pump to fil the box with as it makes less mess and is alot easier.

As above,I change gearbox oil every second engine oil change,same with the diff.Spreads the workload and the cost...an oil syringe is the perfect tool for the job,sucks the oil out of a 5 litre container and squirts the stuff into 'box and diff.

Lovely, cheers guys, thanks for you help

What oil would you guys recommend for the gearbox?

I use 80w/90 gear oil in diffs(open!!) and in the gearbox of my 316i.I use ATF in the gearbox of the 2.7,because I have a short shift fitted and 'er indoors was moaning that 'the gear thing on your car is too stiff for my arm'!!
