Curt,
Go back in the archives to February. There was a lot of discussion on the
tranny fluid back then. Here is one of the post from that time frame.

Just wanted to let everyone know I've tested 2
synthetics in my 5 speed transmission:
Redline MTL (GL-2 thru GL-4 equiv.)
Amsoil (GL-2 thru GL-5 equiv.)
This was just a basic test to see if I could tell
the difference in speed (shifting) and normal drive
shifting smoothness. I used a mixture 1 quart Mopar
manual tranny fluid with 1 quart of synthetic. I
gave each synthetic 5k miles. Also I hope the Amsoil
did not contain reactive sulphur which could damage
the synchros in the transmission. I could not find
any data on this oil that said it did or did not
contain it, but decided to give it a try. On the other
hand the Redline MTL label stated that other brands
contained reactive sulphur and implied it did not.
So after 10K miles the hands down winner in my opinion
was the Redline MTL. Much smoother shifting than the
Amsoil. The MTL started out very smooth and ended the
test in the same way, compared to the Amsoil which started
out good and went downhill (slightly chunky in shifting)
I feel the Amsoil caused me to miss a downshift the other
day from 5th to 2nd causing hellacious wheel hop. I've
never did this before and what a rush!!! Well the Amsoil
was drained Sunday morning and in went more Redline/Mopar
fluid. I'm going to stick with this combo for a while. BTW
I'm taking the liberty to repost Bill Maurits excellant
thread on the identity of the Mopar tranny oil.

I finally go to the bottom of this Manual Trans Fluid issue. I called
Quaker State's
tech info line. After running the # for it (MS-9224), he told me that it
is (drum roll)
called "Synchromesh" and is made by Penzoil. A 75W85 API GL3 Gear Oil.
This however is NOTregular gear oil. It is kind of a hybrid between gear
oil and
motor oil but not a "mix" of the two.The GL# rating says that there is
considerably LESS sulphur in the oil. The added sulpher increases the
pressure
and heat the oil can withstand. GL5 has the most sulphur and is used
almost
exclusively in rears. Apparently the metals they use in the gears and to
coat
the gears with is harder and more resistant to the corrosion that the
sulphur causes.
Normally a GL4 gear oil is used in Manual transmissions because the
metals are
"softer" and the GL4 oil has about half of the sulphur of the GL5. But
over the long
haul, there is still usually some corrosion and varnish that occors.
As far as he knew though, no one makes a direct synthetic replacement
for it.
But the good thing about it is that it is a pretty good oil in it's own
right.
It is good for up to 300 degrees and has a pour point of -50 degrees.
The severe service change interval is listed as 18,000 miles.
That's all I have for ya everyone. If you have any more questions, drop
me a line!

This goes back to a question I asked a month ago or so. What the hell *is*
the stuff? I have no problem using something else (specifically Amsoil),
but I want to know exactly what weight etc. the Mopar stuff is... Noone has
been able to tell me so far.
