Calls to mind, years ago, when I was parting out a Jetta and, as usual, I wanted to drain the keeper-salvage trans and install some other oil for storage.
Some moron, who was absolutely jacked-up on meth, holding a 20-foot cheater bar must have last installed it. I tried EVERYTHING to get the plug to back out. Nothing worked.
Finally, I fired up the acetylene torch with #2 tip and produced a circular non-stop rotation around the plug until the aluminum was too hot to even think about touching. Waiting a half minute......re-applied torque to the plug.....and it slowly turned out.
I did elect to throw away that original plug though. But, no cracks in the case.....threads seemed just fine. Life went on. Turned out to be a REALLY nice trans. Blue ink would be prowdd.........
I would elect to send that AWY trans to "the promised land" with that bizarre final drive ratio. Isn't that one of those with the 4.25 ring? Of course, might be handy if living in hilly country. The ACH's are wonderful for normally-aspirated cars.
