    Finally failed after 14+ years of ownership. I started getting crunches going into 3rd a week ago. It was OK with double clutching and I was wondering how much a rebuild would cost. Then the temp gauge started fluctuating quite a bit one evening. Checked coolant - low. Adding brought up some drops of oil.

    Oh, right. Best guess, I drove it about 50 easy miles after it started leaking.

    Since AW Italian is 1.2 miles from my office, I guess that's where I'll pick a new one up. My intake gaskets are original so I'm going to pull it for the replacement. Car is on the lift waiting my attention.

    My daily VW has a bunch of 60k mile maintenance needs plus needs a waterpump but I punted and dropped it at my friend's shop so I can concentrate on the Ferrari. And my Ducati track bike. And my Aprilia RS250 track bike. :) It pains me to pay for stuff for things I can do myself but there's only so much time.

    Feel for you. Mine failed in the driveway at home right after washing the car. It took 6 weeks to get the exchanger from Italy (slow boat? row boat?) + 13 (THIRTEEN!!!) fluid flushes to clean out the coolant system and gearbox. Best of luck w/yours!

    Is it a spider? It's a bit of a job for a spider.

    I have no plan yet. :) Many oil changes with cheap 75w90? On the coolant side, my fingers are crossed that it's not too bad. I haven't drained it yet.

    This is what came out of the transaxle:

    This will go slowly. I pulled the side panels and airbox this morning.

    I'll probably do the trans mount while I'm in there.

    Fortunately, it's not! I skimmed through the service manual this morning. In sterile manual-speak, it sounds pretty straightforward.

    I haven't looked into it but I thought shops use ATF for a quick clean - not on the road just a few minutes on lift in gear
