Best trans fluid? - Diesel Forum

texasjack308 · 08-24-2007, 11:37 AM

Any suggestions on best brand/type of trans fluid? I'm bringing my 00 SD back from the dead, no telling when the previous owner had changed it last.

I like Mobil 1 synthetic ATF.

Its good to have you back Mark. Long time no posts. You are convinced that the new formulated Mobil 1 is OK for our trannys?

Yes, I am. Ford changed the formulation of MERCON V so that it is compatible with the transmissions that required MERCON.

I went with Schaeffer Oil's Synthetic. Less expensive than the stuff in the parts stores, they'll ship a 5 gallon bucket to your house. And if I remember correctly, Brian's Truck Shop uses this in their trannies. Just my 2 cents.

Thanks for the infor!

Brian put Schaeffers in mine, after the rebuild...

I then switched to Mobil 1, and found it ""EXPANDED"" to much, and blew tranny fluid out over everything.... [img]/ubbthreads/images/graemlins/mad.gif[/img]

Went back to Schaeffers, and every thing is FINE.. [img]/ubbthreads/images/graemlins/smile.gif[/img]

Next option, after Schaeffers would be Royal Purple... [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Amsoil, has got to much lubricity, and may have been the cause of my tranny failure, so I "PERSONNALLY"" would NOT go back to that.. [img]/ubbthreads/images/graemlins/vomit.gif[/img]

I GUESS YOU COULD SAY, I'VE TRIED 3 OR 4 DIFFERENT TRANNY FLUIDS, AND YOUR LOOKING AT SOMEBODY WHO HAS ""PAID THE PRICE"" TO SAY WHAT I DID... [img]/ubbthreads/images/graemlins/bleh.gif[/img]

Yep, Mark's back under his old username. Actually, he's been here all along, but only the moderators/administrators knew his alias.

Click here to read his version.

Another very fine tranny oil is Chevron Drivetrain Fluid. It is compatible and is recommended by Caterpillar, Cummins, Allison, John Deere, and several others that I'm forgetting.

Any different recomendations for a hand shaker?

johnnieboy · 08-26-2007, 04:12 AM

No. The ZF6 stick shifter requires the same ATF as the automagic.

Mark, do you know what was changed to make it compatible with Mercon, what did they add or take out of MerconV
