Transmission oil

[Newbomb Turk]

I am happy with what I got guys.

Do you really think Red Line oil makes a gear lube for manual transmissions that won't work?

That is absurd.

Did you bother to pick up the phone and call them and let them tell you why you can and should use a synthetic gear oil?

That would have been a better use of your time than posting your question here, where some of these guys are stuck in the 1970's and can't get out.

Use what you want, but there is better out there.

Lol, settle down there big shoots.... My fault for saying you "cannot" use synthetic, you should just use GL4 because its proven. Better oil how? Explain, you still have not. I obviously touched a nerve and you want to be right so bad its killing you, but still no math, backup, evidence. Why would one use a 'better' oil if a GL4 run brass synchro'd 4 speed runs great seemingly forever? That is the point I am trying to make that keeps bypassing your superior wisdom.

I did not post any questions here, I was replying to the original poster on here. That seemed to have escaped your superior intellect as well?

Yup. Proven. Got it. You’re the smartest. You’re the best.

I’ve already explained that you are so ******* smart I can’t explain jack **** to you.

Move on asshole.

Actually you have not explained anything to anyone. I am citing Brewer, the builder of the OP's trans, and any and all 4 speed builder like ever.... You are citing who? What evidence? I have never claimed to have your wisdom or intellect, I mean that isn't possible to have TWO people that smart is it? I am claiming to follow decades of vetted experience, including my own with my A833. Still waiting for your evidence/explanation on why synthetic is BETTER in a brass synchro'd 4 speed than mineral GL4 kind sir

What you don’t get is I don’t answer to you.

You think I give a **** about you or what you think.

I do not.

 

[Muswagon]

You owe the original poster an answer tho ;) you must give just a little bit of a **** or you would have let this go an hour ago…

No, I just detest pricks like you. I don’t owe the OP an explanation either.

I’ll end this thread by saying if you are so ******* stupid you can’t find a synthetic gear oil that works it’s because you don’t want to.

In 1979 I started using synthetic gear oil in brass synchro transmissions. Still do.

I even use a GL-6 gear oil. But you can’t do that because that’s what you’ve been told.

You’d be wrong.

That’s all I’ll say. Now **** off.

 

[Muswagon]

So pay a premium for oil that all builders would say should not be used in an old school 4 speed? Your signature is bang on, very wise.. I think you are still mixing up can’t and shouldn’t… I can quote a thesaurus for ya.. ok you hang up, no you, no you… talk soon

Man, only November and Winternet has hit FABO already....

Note that Jamie Passon also recommends only GL4 90W or 140W gear oil..
For later manual transmssions besides our A-833s, maybe the synthetics may work just fine.
But I trust Brewer and Passon, they are Mopar guys for our A-833s...

Just my $0.02...

Don't forget about the tranny fluid, it's getting cold up here......

"If shift effort becomes extremely high..."

Being in Mini-scrotum you probably know this all too well, but for those in warmer climes who aren't aware: Shifting an A833 full of SAE140 on a -25°F morning is a lot like trying to kayak through wet concrete.

 

[sinitro]

Yup...
The A-833 had large gears and as the temperature got colder below 40 degrees it was harder to shift the gears.
Mopar made that recommendation in multiple places, attached is a lift from the 1970 Plymouth Service Manual.
But in Southern California, where the temperature typically stays above 50 degrees 80/90W or 140W GL4 gear oil works just fine..

Just my $0.02..

Found the updated version of fluid recommendations....

I drive on the street, and I used to drive my HotRod 4-seasons.
In my effort to switch away from what I had been using, and go to full-Synthetic, I discovered that my trans shifted real slow with it. I reasoned that the oil was just too slippery. I took the trans down several times to modify the the brake cones in a couple of ways, to help the oil get off. I even tried changing the finish on the cones. That's three times I took it down. My record is 17 minutes and includes dropping the Shifter, the GVod and the Pipes.
Finally I gave up, and dropped the trans one more time, to completely tear it down, to wash out ALL of the Synthetic.
After she was back up, I re-installed the previously removed oil, and the thing shifted like lightning, all the way to 7200, my favorite shift-rpm.
My recipe was simple;
50% dextron III, and
50% 85/90 EP oil.
I used to run straight ATF, but eventually added the EP oil to;
1) keep the cluster-pin from wearing out prematurely, and
2) same for the mainshaft pilot, and
3) the cluster seems a bit quieter banging back and forth in it's endplay.
4) if you run the A833 od box, then, on the Hi-way, top gear goes thru the cluster , therefore; saving the Mainshaft nose is top priority, as the shaft is always turning at a different speed than the input, in all gears except "third"; and, on the hiway, the power is always going thru the cluster.
The only time those two get a rest is in Direct, which is Third. Furthermore, that od gear spins on a reduced diameter mainshaft with no bushing.
Thus E/P oil was, IMO, mandatory.
Furthermore, I run the alloy box for it's ability to run cooler; and same for the alloy tail.
Those changes were made in the early 2000s.

So, I don't care what you guys all run, but I know what it takes to marry a lightning-fast shift to a long gear life; and brass that last 125,000 miles....... or more, cuz they're still in there.

and yes, I slick-shifted the clutching teeth on second and third, but left the brass in there. This alone was a super improvement, but was done separately from the synthetic-oil escapade.
