Hi all,

Frustrated. Jack the car up (rear ramps and front jacks) remove the panel to the transmission. I realize it's impossible to get a ratchet wrench to open the 8mm fill plug for the transmission.

Does anyone have any idea on how to gain better access to the transmission plug? It looks like it's blocked by the subframe. My only solution would be to find a stubby allen key, but then I wouldn't be able to torque the plug to spec.

Do you have a photo? What transmission 8 mm fill plug?

Cut an Allen key, stick in hole and turn it with a box wrench

Use 3/8" drive allen key, turn with open end wrench

This is how I do it as well on both my cars. Used an angle grinder to cut an 8mm allen to size, insert into fill plug, then slide the 8mm box wrench over it.

Otherwise you need to buy the tool from BMW. No other good solutions.

I'm going to give this another go soon. I'm planning on dropping the transfer case brace which I'm hoping will drop the transmission just enough so I can access the fill plug.

I would ideally like to cut an allen key, but I don't have an angle grider, just a dremel which I'm assuming would struggle to cut hardened steel.

I bought this but have not used it yet:
