MTF Comparisons?

[jonn6464]

Hey FABO,

Just wondering if anyone has ran these (possibly all of them), and can report on quality.

Valvoline Synchromesh vs Pennzoil Synchromesh vs Royal Purple Synchromax

For use in an A833 (non OD).

Thanks for any replies.

No experience with those.

I used to run 100% Dextron II.
This shifts great! But, leaves very little protection for the cluster pin. So I swapped half of it out, in favor of EP gear-oil. It didn't slow the shifts down that much, lol.
I think I used maybe 80/90, or 85/115; I can't recall anymore, other than that it was a light viscosity.

Just so you know; altho some FABO users report success with synthetic blends,
I had zero success, and I really tried hard to use it. For me, it was just too slippery, making the shifts just too slow, for me.

I have run the Pennzoil Syncromesh. It worked great.

This trans repair guy says don’t use any of the synchromesh fluids in old cars.

skip to 11:20 for the oil talk.

Crap! I just Filled My New 4-Speed with Valvoline 75W-90 Gear Oil...
It say's it's for a Non-Synchronized Trans? What will I do now?? Drain it before I spin it?
or Send It and see what it does?

Better hone up on your double clutching!

I filled mine with 75-85 GL4. I was told not to used GL5 because it ruins the brass.

Red Line is what I use in my 3 gear boxes. No issues and the brass looks great.
