Changing tranny fluid-royal purple

[STEEDA SNAKES]

I have some questions on which royal purple to use. I currently have redline D4 in the '98 Cobra (Tremec) and stock fluid in the '01 Cobra. I was wanting to change to royal purple, but I am not sure if I should use the "Max ATF" or the "Synchromax".

I have already done the search thing and it is still unclear, which to use. I called Royal Purple and they said to use the "Synchromax". In an earlier thread, someone stated that the technical support at Royal Purple had stated to use "Max ATF" if your tranny called for Mercon or Mercon V, which is what our trannys call for, as per SVT owner's guide supplement.

Still confused, which royal purple are you using? Oh, and what are everyone's recommendations on the '03 tranny?

Posted on sn95, new edge and terminator forums.

Thanks

Synchromax. It's what I use and what the speed shop recomended to me.

Thanks, I bought the synchromax and plan on changing it in the '98 tommorrow.

The '01 & '03 will be next. They came from the factory with Mobil 1, did you notice any improvement in your tranny after you switched to Royal Purple?

YES, smoother shifts. It's good stuff.

Quick question, where do you get the Royal Purple Synchromax? The local parts chains do not sell it. I'm in SoCal. Thanks.

In Texas, O'Reilly Auto Parts and NAPA Auto Parts carry the RP Synchromax. Don't know if that helps. :shrug:
