[200q20v] transmission lube

Hi David,

Before going to that extreme, try a half can of engine stop leak, seal
restorer in the tranny and the other half in the rear diff.  Drive it for 1K
miles and 95% prob that your leaks will be gone.  You may have to gunk the
underside down or steam clean to be sure that the leaks are stopped.  At $4
or 5 bucks, a cheap fix.  I've kept original shaft seals leak free for 250K
with this method.

The tranny uses GL4 gear oil and the rear diff GL5 hypoid gear oil.  Any
brand, mixed is OK.  What ever is on sale at Pep Boys.

Happy new year,
