Hello Listerns,
Can anyone tell me where 75/140 or 80/140 gear oil for the trans, and diff.
on TC's are available??? Oil should be to Gl-2, Gl-3, or Gl-4, NO Gl-5, which
has too much sulpher and is harmful to bronze bushings.
Any help will be appreciated.

You can buy sinthetic oil direct from Redline. I believe there minimum order id
two quarts.

If you check out my web page, I list the Redline oil for the TC.

Red Line Synthetic Oil is great oil, and I would use it; but the earlier inquiry said it must meet GL-1, 2, 3, or 4 ... All the label says, is that it exceeds GL-5 and GL-6 Levels of protection. After all, sulfur isn't all bad if compounded right. If sulfur additive handles higher pressures of tooth and shock loads, so we may have to replace a $5 bronze bushing... How much are gear clusters, now? That is if you can get them.

The oil in question does not harm yellow metal. You can verify this by contacting Redline.

You'll be replacing more than a $5 bush if the bronze bearing carrier
in the front pinion bearing in the differential gives way. Both TC
diffs that I have pulled apart had ordinary EP oil in them and the
bearing carriers disintegrated when I removed the bearing. I suggest
a low EP oil such as Penrite's Mild EP for both differential and
gearbox.

Gentlemen,
It seems clear that a 75-90 GL-4 gear oil, such as Red Line MT-90, is worth a
try in the TC gearbox. What about the differential? Is this lighter viscosity
gear oil sufficient for a differential application in a TC? Is simply draining
the gearbox or differential of GL-5 fluid enough or must it be flushed to
decontaminate the yellow bits before refilling with GL-4?

Jim ;
It just came to mind that you were equating Redline MT-90 to MG Spec. of 140
wt gear oil. The MT- 90 is a 75W-80W gear oil with viscosity of a 40wt
engine oil & is what I use in my 5 speed daily driver.
The Redline equiv. that they recommend for diff. is a 80w-140 wt oil. For
the tranny it is 75w-140 lub. As I recall they advised that none of their
GL-5 lubes incorporated additives that attack yellow metals.
I never discussed advisability of flushing a previously used GL-5 lube that
may have used undesired additives. . If these were used long term probably
too late & new GL-4 lube unlikely to rehabilitate. Back in the day I only
used straight Shell 140 gear oil which was generally available at any Shell
station.

Best to go straight to real experts & contact Redline & or other suppliers
Cust. Sv./Tech support Dept direct, rather than rely on urban legends &
antecedentnal knowledge. My experience with Redline has been excellent with
no attempt to "up sell". A consensus can be developed by posing same
questions to other mfgrs. C.S. or Tech Support Depts.

I wouldn't do this for the final drive gears but I'm sure the transmission
would be happy with modern or Hydraulic oil.
They both have additives that protect bronze. I used ATF in a Muncie
transmission all year round years ago. With gear oil it was very difficult
to shift in the winter.

Hi Whitworth Heads,
I can report no adverse results and pleasant shifting using Redline transmission oil and gear oil in the differential since 1991. However the OEM double race pinion bearing race had been destroyed by high sulfur E-P additive used in in the 60s (I replaced it with 2 Timkins).
By the way, the camshaft and tappets apparently didn't like each other bathed in Redline. They had to be tossed out after 10k miles. Thanks to Manley Ford I've learned to make sure the tappets are all turning and I've had a conversion to using Penzoil racing, Brad Penn, etc. oils in flat tappet engines.
It seems just like us being adversely effected by eating processed foods, our old treasures can be harmed by sneaky chemical changes.
