But when you get the car, drain the fluid (look for metal shavings, a couple is fine, excess and your in trouble) and fill it with Royal Purple Synchromax. Next oil change, put in all 6 quarts... Hard right turns own these cars, many spun bearings. Thats all I got right now.



this is the mtx version if i forgot to mention that and it is 1999.

so drain the transmission fluid and fill it will royal purple syncromax?



Yup, the SVT's only came in MTX. And I have a 99 too

Drain the fluid, there is a plug on the facing the back of the car, that is the drain plug. I think its a torx bit or something of the sort. Once its all drained, put the plug back in and use the fill to spill method. It should be roughly 3 quarts +/-

And I would suggest Royal Purple, its what Im running and I love it. Others will say, ford honey... you know how that game is played. Just don't use Redline MTL
