which synthetic ATF?
 

What is my best choice for Royal Purple synthetic tranny fluid for my 1990 world class T-5?

Synchromax or Max ATF?

Synthetic ATF is what Walt told me to run in my TKO. I can't imagine that a WC T5 is much different.

Hi. Which Royal Purple synthetic transmission fluid is
recommended for the application below:
1990 Ford Mustang GT
5-speed (manual) world class T-5 transmission
I believe that Dexron II ATF is recommended from the factory
but not 100% sure.
Do you recommend Synchromax, MAX ATF, or something else?

They replied the same day....

We recommend the Synchromax for this application.
Holds a bit less than 3 quarts.

anyone else know?

Re: which synthetic ATF?
 

I went out in my "stable" and bigger-an-shyt it's Syncromax. You were right!

Re: which synthetic ATF?
 

holy sh*t! i rec'd another email from Royal Purple today, I guess since the automated question form on their website CC's someone else as well. he said:

Synchromax is the recommended fluid for your transmission.

Two replies in less than 24 hours, they are good! and if jester agrees then it must be true!!!!!!!!!!!!!!!

Re: which synthetic ATF?
 

Hell, if Royal Purple and Pro Motion BOTH say to use Synchromax (Why can't I ever spell that correctly???) then go for it!!!

That's what I run in the TKO, and I've had ABSOLUTELY 100% ZERO problems with this tranny!!!!
