My M135i gearbox plugs didn't have any kind of seal/gasket/washer from the factory.

So how did you make sure it sealed properly ? Teflon take or liquid gasket ?

I just torqued them up, it's been fine, so far.

Changed oil for Total gear 9 FE, but I'm still not completely satisfied with the cold shift.

Somebody has experience with ATF in these manual gearboxes? (120i 6-speed manual)

Cheers guys, thanks for the input.
The thing is, that for my 120d 2007 FL, on realoem, the oil recommended is MTF-LT3. The BMW original oil is 75W-90, where the redline is 75W-80. Will this be an issue for the car? The genuine and redline oils are mostly the same price for me, so what do you guys think? Should I get the Redline or BMW oil? Also..can I get a link for the exact product, so I won't get confused (Redline).

Many thanks,

When I had cold notchy manual gearbox, Red Line Shockproof oil did the trick for me - it was a very long time ago, don't know if this is still a recommended thing to do.

I just wanted to say thanks for this really great guide!

Managed to get out in the sun and complete this a couple of weeks ago, very easy steps to follow - hardest part was actually jacking the car up; especially as I had to do it twice having discovered the covers I had left 'in a safe place' ...

One thing I didn't read in this thread was the torque for the new plugs, which I found online here if anyone's interested:

For the record, I used Castrol Syntrans from Opie oils.

Had it changed with royal purple in the 130i manual at 145k km.. shifts feel slightly easier. Very little difference. Not sure how long these oils last but wouldn’t have bothered for just the shifts.

When I just got the car first/second/third where a bit stiff. Which was too slow for smooth shifts. After being a bit more forceful, to get shift timing right, that stiffness was reduced. Maybe that’s why the difference is now quite small..?
