3650 tranny fluid change

just wondering if those of you with the 3650 noticed and difference switching to royal purple synchromax, my cars only got 27K on it and i had the dealership replace some syncros early on when it was under warranty (probably at about 10 or so K) so its not that i need to change it, also is there a specific place to pour the fluid when you take off the shifter? or do i just pour it in there. i think it takes 3.6 quarts, which is different from the t45s which i believe are 3.2, im not sure though

I believe if it's like all manuals, there will be a fill plug from underneath. But the last ford I'll dealt with had the t-45

i know theres a fill plug, but ive heard its a pain in the *** bc you basically have to pump it in there, ive heard alot of people that put it in from the top where the shifter is

if you do it from underneath you will need a pump or a piece of tubing long enough to turn the bottle upside down and squeeze it in. The fill plug is in a horrible spot on the passenger side of the tranny.

Here's some info that I dug up. http://en.wikipedia.org/wiki/Tremec_...0_transmission

TREMEC engineers have recommended Texaco-Havoline Dexron III/Mercon Non-Synthetic ATF. The most recent Ford owner's manuals specify 3.17 quarts of a non-synthetic Mercon ATF. There has been a significant amount of confusion regarding the proper capacity and proper type of ATF for the TR-3650 which may have a correlation with a rather large number of complaints about notchy shifting, shift "nibbling", noisy synchros, and grinding gears.
