Oil leak from top of trans

[aus335iguy]

So found this explanation ... wondering if we can access this from inside the car when the GWS is removed ?

Also, given the number of gaskets that leak should we look at venting?

Access the harness plug seal? I don't think there is access to the transmission tunnel from inside the cabin. The GWS is an electronic box and not physically connected to the transmission like a manual. Unless you're trying to say something else.

When you remove the GWS you have a huge hole in the car and you are staring at the transmission.

Oh really? I didn't realize that.

That’s what i was hoping ! That you could identify if that was where the oil was coming from

If nobody gets to it before me, I'll be taking tons of photos during my dct swap and I'll be able to answer this question then. I'm sure someone knows the answer this this however

At best you would have to droop the transmission as far as the engine mounts will allow but it is far easier to just remove the transmission. Every person has their own limitations (large hands, patience etc).
On the M3 the additional cooler makes access even more frustrating.

This will allow for thorough cleaning, full access to the side pan seal and some car pron.

Anyone with a wet bottom pan or suspicious side pan should invest the time to inspect the connector sleeve as it is a common failure. When it leaks, Getrag have even so kindly provided a hole for the oil to escape downwards.

Great advice I

Car pron ?
