Air cool VWs use any old 80-90 w gear oil. I don't know what GL4 is. You can buy it at any Pep-Boys.

I found the Hypoid stuff at Pep Boys. It seemed to be advertised towards 4-wheeler gear boxes or something. I don't remember exactly.

I am, however, still curious about the transmission fluid/oil that I need for my frontier. Everyone on the frontier forums says GL4, but I know thats damn near impossible to find.

Thats hard to believe. What do the Nissan dealers use ?  Can you not buy it at the dealerships ?  They have to service transmissions there I would hope.
     My '86 Trooper used 30 W oil in the 5 spd. transmission.

Yeah Nissan has their own oil, but I think it was about $18 a quart, and for 5 qts, I was looking at my options!

Yeah, I know about those lousy trooper transmissions... the manuals just used motor oil! The automatics though can be a pain (just went through this with my brother in law)

Lousy transmission ??  I put about 180,000 miles (a lot of off road) on my Trooper with no problems other than 2 water pumps, EGR valve, 3 timing belts and normal service stuff. I wish I could buy a new one today just like it .  About 23-25 miles  per gal. on a great 2.3 engine. $10,500 W/air. One of the best rides I have ever owned. $18 a quart   Be glad you are not buying power steering oil for a early Audi. $35.00 a qt. If you used ATF (like most cars did and still do) you had about a month before it puked.

Indeed sold it to Jim.  I loved that car. It never let me down never in the 15 years I owned it.
