98 stang cobra, trans fluid?

I have a friend whos about to do a fluid swap on his 98 cobra... I dont know much about ford or his trans but I was wondering what sort of royal purple fluid would be used?

I'm taking a stab at it and guessing synchromax but I just want to double check :D

thanks guys

hey, no fluid swaps...a flush is better...fluid swaps only 5 - 6 quarts...a flush can have beneficial additives and 'swaps' 10-12 quarts...see ya!

Thanks for the info! But I need to know what royal purple synthetic fluid should be used?

I have referenced the RP website for trans fluid, but I dont know much about the car cept its a manual 98 cobra with the 4.6L I do believe.

Anyone else?
I want to hear from someone who's been around on the forums like myself.

Its hard to say. The owners manual may tell you. I know the stock 5spd in my truck takes dexIII. But my 3550 takes syncromesh.

ive run all the brands atf synthetic fluid in all the stangs so far, helps improve the lifespan of the junky t45

i kno this is kinda an old topic but here is my .02
at the dealership i work we we have a universal atf tat works for all major transmissions but the new cvt trannys
if u take it to a dealership it may cost more to have the tranny flushed but we havent had any problem with them over the last few years

jsut my .02
