How many qts does it hold? Does it take ATF or gear oil? I'm guessing ATF, I'm going to make the switch to RP to see if it helps makes things smoother and quite. I'll post my findings. Also if anyone needs to know where to buy Royal Purple online, buy it from American Muscle. Their prices are on par with local places for the most part and they have free shipping, not to mention the discount code: mustangforums

 

Royal purple ATF! Not sure the # of quarts but I know it was said on here before....did search help at all[sm=smiley23.gif]? J

 

Yup, I did a search. I found TOO many different answers regarding to use ATF or the Syncromesh. It's 3.2 quarts for anyone curious, according to the search.

 

Would changing the fluid make a diff that would be noticeable??

 

I had Redline D4ATF in my '06 GT 5 spd, it worked well. I just changed it again and put in Royal Purple Syncromesh. No big difference, but maybe a slight improvment.

 

Yes. So does anyone have the real answer? ATF or Syncromesh?

 

Redline MTL oil FTW!!

 

That doesn't help me.

 

lol. how often should that be changed?

 

30,000 miles, I believe.
