Transmission plug size & torque?

Stevesas12 · 08-07-2021, 04:04 PM

Hi guys,

I did try & search the site first for info on these sizes, but didn't find a clear answer.
Someone said M18 , but isn't that a torque bit? Isn't the transmission plugs just a hex type?

Just want to get tools together before on ramps etc.

Thanks

The drain and fill bolts are both 8mm; torque spec is 26 ft-lbs.
I have used ~1.3L of fluid, IIRC.

The following link is for a 128i but is very similar for our cars:

Buy 1.5 liters and you'll have plenty even if you have a crappy leaky hand pump like mine.

Also OP- you probably already know this but MTF-LT-5 is identical to Pentosin FFL-3.
