Default New guy needs help on G50 Tranny fluid change - hole in tranny?

Jacked the car up no problem (the jack pads make it super easy). I am having trouble reaching the fill plug due to the clutch linkage being in the way. What tools have used guys used to remove the fill plug?

My G50 requires a 10mm socket bolt. The one I have is fairly long so I am thinking I could grind it down to half the size to get more clearance. The plug seems like it is going to be tough to get off so I am going to need a fairly stout wrench to get in there.

DO NOT cut corners here .. a mistake on this could be miserable.. lots of rounded plugs out there which now require gear box drops. On my 944 they one i borrowed was great it was made out of a bent steel handle welded to a hex drive that fit perfectly .. no issues.

Yeah, my 915 came with a rounded out drain plug that is causing nightmares. It's always better to buy or rent pro quality tools.

One other thing I noticed while crawling around. Towards the back of the tranny there is a small rectangular hole in the bottom of the casing. It looks like it was machine cut and not a piece that has broken. The hole exposes one of the gears.

To my knowledge I have not leaked any fluid but will know for sure once I get the fill plug removed. Has anyone else seen this before?

Use an allen socket of the proper size with a ratchet. As ice says, no cutting corners here by grinding down a hex key. I'm assuming a G50 fill and drain is similar to a 915?

Ed my 915 is a plug with a bolt head style so I just need a socket or wrench .. my 944 was a socket head so i needed a giant hex... and HATED that set up .. but i guess they saved metal and it was lighter

Great thanks for the tips. Are you guys using a 1/2" or 3/8" drive socket for this one? This bolt seems pretty stout so I am thinking 1/2" drive but that will not give me much clearance.

Do use some Kroil or other penetrating oil, as well...I always do.

Ok here are pics from the small exposed area in the back of the tranny I was talking about. Why on earth would this be exposed? It does not look like it was broken but it looks like a machined opening.

Any thoughts? I have not noticed any leaks and it shifts fine. I guess I will find out how much fluid is in it once I get the fill plug off.

Yes as Kevin (SyZyGy) guessed, that is the starter ring gear. So inside this compartment are all your clutch components. The internals are sealed so none of the dirt& moisture is able to get into the trany.

I don't know the exact factory technical reason for cutting out a hole, but I can take a couple of WAGs...1) if the starter is in a spot where there are broken teeth and is not engaging the flywheel, you can use this hole to pry the flywheel into a new location 2) to allow some cooling and air circulation to the dry clutch components, 3) so that in the case of a compromised shaft seal either on the engine or trany, this will allow oil to leak out of this cavity, thereby giving owner a warning that one or both of the seals are leaking. The hole also prevents the dry clutch from trying to become a wet clutch should the oil leak get bad enough. I'll let others chime in now.
