Default Amsoil MTF - worth it!

Picking up on an old thread re the infamous sticky 5th gear I followed the advice offered by CW on here. That was to drain the 'box oil and replace with Amsoil synthetic MTF from opie oils.

My 5th was a little sticky but not terrible but I was curious about the fix. Just to report back that after 15miles of driving it was pinging back to centre like a new one. Anyone having this issue then its deffo worth a try!

This is definitely worth doing even if you don't have any 5th gear return spring issues as the gerabox benefits from an oil change anyway contrary to BMWs "lifetime" oil spec which is just nonsense. The shift on mine went much lighter and easier.

would also be good to mention how much oil is needed, where to buy it from? price of the oil? how hard is the job (DIY or specialist) and any other details regarding the job i.e. tools needed, how many people needed for the job etc etc???

OK Here goes - no pics I am afraid

I put my car on our ramps so it was elevated - perpendicular to the floor as opposed to nose up as with axel stands.

Remove plastic under trays

Drain oil from gearbox by undoing plug (iirc it’s a 17mm bolt may be wrong)
Once done clean and refit
Remove plug from driver’s side of gearbox about half way up.
I then used a pump to fill the 'box with oil but if not you will have to put it into a squeezer bottle and fill until it starts to flow out from hole you are filling

Allow to drip and then refit plug.

Job done.

Uses ~ 1300 ml of oil

I got mine from here

http://www.opieoils.co.uk/p-1051-ams...productDetails

I bought two US quart bottles


Allow time for the oil to work - mine took 15 mins of driving but it may take a lot longer ie a few thousand miles.

It's always a good idea to undo the fill plug first, because you never know you may not be able to undo it and you've already drained the fluid

Good advice! (same can be used for the diff), but the gearbox ones can be VERY tight and they're hard to access!!

Old thread but good advice for anyone doing an gearbox oil change. One thing to add is BMW advise a sealant is used on the drain plug threads which I believe is like a white chalk? not sure if you can buy this separately but a Loctite alternative should be available.

Also worth mentioning it is recommended to remove the gearbox oil when warm so drive the car before if possible but as you are working close to the very hot exhaust system care needs to be taken especially when removing the side fill plug.

I used a cheap but effective large syringe and pipe to refill the oil.
