For those that have this transmission or just have some knowledge to share any help would be appreciated. This question refers to a 2004 trans. What fluid is recommended ? The forums (Mustang) are all over the place. Even Tremec themselves are a bit misleading. Regular Dex 3/ Merc. to Mobil 1 full synthetic to GM/Pennzoil Synchromesh. I've read so much about each, pros and cons, blah, blah, blah. What do the people on HERE know?

Thanks in advance, Mike.
