Royal Purple Gear / Manual Transmission
Going to be replacing my Rear Diff and Manual Transmission fluid with royal purple...I was reading on the royal purple website that the transmission and rear diff use the same fluid?

Is this right?

RE: Royal Purple Gear / Manual Transmission
I also found this but I dont understand what this means...
"synchromax is recommended for manual transmissions that specify an automatic transmission fluid or motor oil."

The manualtrans.on 2005+ Mustangs calls for MERCON ATF (V-6 2.75QTS--V-8 3.2QTS)not manual trans. fluid.And the rear calls for SAE75W-140synthetic(7.5 3.25PTS-- 8.8 4.25PTS). This is in your owners manual!

New transmisson do get smoother over time. I use RP MAN. Trans. fluidin my T-5 but it felt the same shifting wise as it need with some clean ATF that came out of it. I use it because it is synthetic, which I believe has a real world advantage, as protection/lube goes for the mechanical part, over the conventional stuff. Whatever oil/fluid use use, keep it clean.
