I have decided to keep my 335d now and as it has been off the road since January I would like to do some general servicing on it.

Previously I understood that the gearbox in mine was a sealed for life unit, however the opinion on this seems to have changed.

Mine is a 2006 '56' plate and on 98k miles.

Could someone advise if I am likely yo have a plastic or metal sump and where the best place to get a comprehensive service kit from?

I have access to a ramp so guessing that with that should be easy enough to DIY.

Interested in this as well...more so the diy part

Hi

See http://www.e90post.com/forums/showthread.php?t=969004 i'm sure the diesel is probably the same.

Thanks. Looks pretty straight forward from that.

you will most likely have the plastic sump kit

you can buy the genuine zf kit - this is a good price -

however when I changed mine i went through incar motorfactors with teh Meyle kit - had no issues with it. Check on realoem to see which gearbox code you have or give the guys a ring and they will be able to tell you the suitable kit for your car

word of advice for the sake of £20 replace the mecatronics sleave as the sump has to be dropped for it to be replaced.

changing the fluid over is quite easy however there is a set re fil procedure which you will need BMW DIS software to do as the oil has to be at a certain temperature/reset gearbox adapataions through the software

iirc not all the fluid comes out approx 1.5 litres remains in the torque convertor but personally I ddi notice an improvement at 110k miles

So the car would need plugging into a BMW program to complete the change?

Also is the mechatronics sleeve included in the service kit?

As for the resetting and temps, haven't done it yet but I have ISTA D, NCS, and INPA so should be covered there
