Im wanting to put some royal purple tranny fluid in my super duty t5, and i know its supposed to be ATF fluid but royal purple kinda has 2 diff. fluid. They have a regular ATF fluid for DexronIII/Mercon trannys, and they make a fluid with a 10w called the synchronizer that says its for manual trannys that specify to use ATF fluid, so which one is better which one do i use?

If you are going Royal Purple you can use the the ATF or Syncromax with no trouble. The synchromax might be a bit higher grade and has some additives to work better with different types of synchro material, but really either one would provide superior performance being that they are both synthetic.

Calling the tech line is never a bad idea.

Good luck.

I used the regular RP auto trans fluid in my '89 GT's T5 and to be honest, I couldn't tell a difference between that and the 100k mile petroleum fluid that was in it. Waste of money for a streetcar IMO. It's not purple, BTW.
