Do this before you get heroic with a big lever on the allen wrench. That will get you a stripped out plug and you will really be screwed. With heat, the aluminum housing will expand more than the steel plug and tend to loosen it's grip on the plug. Whacking the plug square on the side with a stiff flat ended punch and big hammer will shock the plug in the hole and loosen it too. Using a chisel will expend the energy on cutting the plug while the flat end punch will put all the energy into moving the plug and deforming the hole. Then you can use the chisel to turn the plug it the Allen won't work.

Schocki's way to do it. The problem is that there is no room to for a socket plus ratchet or breaker bar.

That's a good way how to save some room. Extending the wrench is also easy and you can use a dead blow hammer for the initial movement. I use the hammer to tap the open end of the wrench, this normally works very well.

That is the idea behind the Snap-On 17MM plug posted above. It's shallow enough you can get a good sized wrench in there.

I think a lot of people who put these back in do not understand the theory behind pipe threads. The torque on this plug is something like 15ft-lbs IIRC.

Was to lazy to read in detail, sorry.
Took the picture just for you guys

I bought a 17mm allen 1/2 drive socket at Auto Zone. OEM brand, came in a 3 pack and was inexpensive. The really fun part is getting the sticky goo into the fill hole while laying on your back. Fuel hose attached to bottle won't work. They make a funnel with a line attached, however, the tip won't allow it to fit into the fill hole deep enough. Cut it, but not too short so that when you over-fill the funnel it all pours out because you have to hold it at an angle. In the end, out of 2 quarts I got 1/2 in.

I won one of those at OCIC in Denver, works great.

Dynamite 76

That is a must have tool!

Oh yeah, when you try the fuel hose method, don't poke a hole in bottom of bottle because you think that it will aid in the flow of the sticky goo, through the hose that is.

You forgot to mention how it tasted?

ceedee

i can tell you plenty how it tastes ...grrrrrr
how many quarts do i have to get in again????

I drilled a hole in my battery box right by the fill plug. Works like a charm.

ceedee

DAMN I WAS THINKING ABOUT JUST THAT...LOL

heinrich

yum, it's good with tabasco

On the GT I use the hole in the battery box were the positive cable is feed. Just pull away the grommet and feed the hose to the trans fill hole.

DON'T spill any fluid in the hatch. Gear oil stinks!

Ceedee, whats the deal. Did you get the fill plug out? You never called. Let me know if you still need help.

Ed Hugues said: " I suppose that would work but IMO that kind of thinking and project completion is what has decreased the value of many 928...sorry but thats my perception. Thats just another form of deferred maintenance.

Heinrich said: I have to agree with Ed.

Guys, I think that if any owner was to complete the job this way then I would have to agree with you. But I'm trying in my minds eye at least since I don't know Ceedee, or you Ed, or you Heinrich that the object in the immediate is to get this young fella's transmission working again with AS LITTLE DAMAGE AS POSSIBLE in performing this very simple service. If we ever meet I think you'd come to the conclusion pretty quick that there not much shadetree about me at all.

What I've seen over and over again are lots of guys on different vehicles getting into trouble performing a manual service in their driveway. On a half dozen occasions I've had to go out to help somebody in these situations and the goal to me is to get the vehicle mobile. I've always felt its better to drive then tow. In this case I would have the customer fill up the transmission and then BRING it to me to remove the checkplug. All of the suggestions here, although helpful and would provide insight to someone less knowledgable could also do alot of damage to an aluminum checkplug/transmission in the hands of somebody less experienced.

Thats the area of concern here for me at least is that that the casing gets cracked. If you think you got problems now. Anyway thats the context to which I answered the question, I hope that if you don't agree with me at least you understand my reasoning.
