I did a quickie search and did not get any hits on this so I may have found a couple of other options for gear oil
for the transmission that I do not believe have been mentioned yet? In
researching transmission oil for our Jetta I came across recommendations
for AC Delco Synchromesh and Pennzoil Synchromesh.
I recently purchased the Pennzoil where it has smoothed out our Jetta
tranny quite noticeably and on the bottle it states to be a GL-3
equivalent. It is also significantly cheaper than most of the other
alternatives mentioned.
