Did not have time to check that I used the right (acceptable) lube. In
crankcase Wal-Mart Tech 2000 SAE 15W40. In 5 speed tranny
ESSO Gear Oil GX 80W -- 90 API GL -- 5.
I'm pretty sure you want to have GL-4 fluid in the transaxle. If my memory
serves me, GL-5 will tend to attack the yellow metals, such as the synchro
Gear oil is not like motor oil as far as the ratings are concerned; While
motor oil ratings supercede one another and are forward compatible, gear
oils are not. So, while a GL-5 rating is newer, it is not necessarily
Many people run Redline synthetic. Expensive, but worth it for better
winter shifting particularly, from what I have heard.

I've heard it two ways. It has to do with a phosphorous bronze addative.
I've heard that one has it and will attack the synchros in a tranny
requiring the other. I've heard that the addative is the required lubricant
(or something) that keeps the tranny that requires it, from wearing
excessively. Anyway, put GL-4 where it is required and GL-5 where
it's required. I know Amsoil makes both. I had to look closely before
finding the GL-4 stuff. It's cheaper too! :) Check closely to be sure,
whatever brand you buy.

Mac, Matco, Snap-on you can take a lug bolt and weld a nut to it or
double nut it and use that too. Depending on where you find it, probably
$10 - $20.
