ZF fluid change question.
Where in the world did you find a 17mm hex? Biggest I've been able to find is 10mm.

EDIT: just saw it on Sears web site. Need to hit a bigger store.

I'm pretty sure I've seen it at Sears. I think mine came from some random autoparts store -- I originally bought it for my '74 VW! I like the big allen key since I can put a 17mm wrench on it for more torque.
Make sure you loosen the fill plug first -- nothing like draining the lube and then realizing that you can't refill it.

Not to step on the conversation but it's a good idea to check the fill plug first (Travis 
) and then the drain. Everyone talks about how hard they are to get out, just run the car a few miles and warm it up; they will come out REAL NICE!!!!!

Get ready to wrestle with that plug
I tried using a 17 mm Allen wrench and a 17mm hex socket on my breaker bar, and accomplished nothing. Hopefully, you'll have better luck. Someone mentioned driving the car to warm up the transmission. I wish I had done that. I took my 1990 six-speed Corvette to a Corvette specialty shop, and they got the plug off, but only after applying heat. They changed the transmission oil. On the advice of someone on this forum, I had purchased two plugs to replace the old ones. That was a good idea, because the old plugs were in bad shape. By getting the shop to do the work, I had to pay $80 or $90. -- Eric
