Well to start, the whole no changing the transmission fluid myth is just that. How many miles are on the gear box?

5 speed auto or manual? Auto trans requires 8 liters of ATF fluid, not sure on the manual.......though


Found this info on manual trans fluid @ bavauto.com

http://www.bavauto.com/se1.asp?dept_id=318

Please check your vehicle for the proper fluid requirements. Transmission will be labeled with the proper fluid. This fluid replaces MTF-LT1 and MTF-LT2 BMW original fluids. Please fill or top off with the proper fluid only. Please note: For Vehicles With Either Yellow Or Blue Label On Transmission

From the diagram in the link the fill and drain plugs are on the box #5, normally only auto boxes have a reservoir and most BMW's dont have a res and have to be serviced via the fill/drain plugs, I would think you are filling the power steering....

Fluid level to low, I will do some more investigation as I didnt know they had a gearbox dipstick....

You may have the wrong fluid in:

From model year 2004 some manual transmissions are filled with Castrol “MTF-LT-2” lifetime fluid. This fluid has the
same properties as the “MTF-LT-1”

The “MTF-LT-1” fluid may be mixed and/or
substituted for the “MTF-LT-2” manual transmission fluid.

Marti is correct, there is no dipstick tube for either manual or automatic trans.......the engine dipstick is red & many people mistaken this as the transmission
filler tube.....If you drained your fluid from the trans, & filled the red dip stick filler with Royal Purple, then you just added Royal Purple to your engine, if you added it to the black star shaped round cap, then you added it to your power steering system.......& your trans is making noise, because it is running dry!

This is the procedure for manual trans fluid change:

JB, thanks for the conformation, I thought I was going mad for a minute as I'm really a 7 series man, but know quite a lot about all models and thanks for you link inpost re: manual box fill above which confirms my post#7...cheers.

oldman....you have been running your box with no fluid.....!!, you need to follow instrutions in JB's link if it whines after that youve done damage, if no whine youve taken minimum 10-20k off its life....

You are welcome, It won't mess up your engine as long as you drained the oil out while the engine was warmed up.......to thin it out, so it drains well!
