Ok fellow owners. I have a transmission with a rounded central drain plug screw/bolt. That's the smaller central one with the Torx.

Can anybody tel me what it's made of? I think (hoping) it's aluminium.

I want to drill it out so I can then get at the larger (oil-level) drain plug with its 17mm Allen key. I'm hoping that I can use this 17mm to beak it out and then I can remove the central residual nut on the bench.

Has anybody out there done it this way?
Any potential pitfalls?

Also I presume it's possible to replace the cheap central screw/bolt with a longer headed bolt so I can alway get at it with a socket.
Has anybody done this?
Is it a special thread?

When I stripped mine I was able to remove the drain tube using some vice grips.

Thanks for the tip.

From reading, this drain tube is also a very tight fit. Some suggest it breaks free with a bang. Did you find it needed a lot of twist to break it free. Did you warm the area?

Weyhey. I drilled out the central nut with 8mm drill slowly and only 3/4 of its depth. Had engine running heating up the transmission and banged in a removal socket (reverse thread type) and after a lot of stress it came out. Aha - No Oring in place and to stop a leak someone had torqued it up way to hard. Anyway back in business.
