I have an 01 Mustang GT and have just ordered the MGW shifter. I plan on installing it this weekend and am going to replace the transmission fluid as well. Since RP seems to be the best I am going to go with them but do not know which one to get: Synchromax or Max ATF? I have the Tremac 3650 tranny. Synchromax seems to be recommended for manual transmissions that specify automatic transmission fluid, multi-viscosity motor oil or straight grade motor oil. Max ATF seems to be recommended for all applications where Ford MERCON»® / GM DEXRON® III transmissions fluids are specified. Which one should I pick up? Also how much will I need?

 

I personally like mobil1 ATF

 

i am in the same boat as you, i have a 01 and just ordered the MGW. i will also be changing the manual tranny fluid and have no idea which one to use.

 

well I run mobil 1 ATF and it works very smooth and shifts are nice.

 

Mobil 1 is just as good as Royal Purple. Either one will be fine.

 

So synchromax or Max ATF will work fine? There has to be a difference?
