I'm about to buy a tri-ax soon and heard that royal purlpe tranmission oil will help with the whine of my 3650. If it does help then i want to change it out. How hard is it to change it? I consider myself an ok mechanic so i'm not really worried, but I looked under the tranny and didn't find anywhere to drain it. I'm sure i'm missing something. Any info/links/advice would be great. Thanks guys/gals.

Have you ever changed your engine oil on your own? It's as simple as that.

What do you use for fluid from Royal Purple? ATF? 15-40w? Manual tran fluid?

Dont we use ATF in our manuals?

Another incredibly easy way to fill the tranny is to remove your shifter and pour the fluid in the top of the tranny until it starts to come out of the fill hole. I used about 4qts in my t-56.

What royal purple fluid do I use????

ATF? 10-40w? Manual Tran fluid?

Our manual says it uses ATF so what do I buy?

I think the 10-40w is not for us but ATF or MTF?

Which one?

You can either jack it up evenly, or when the fluid has finished draining, drop the jack so that the car is level while you fill it. The latter is the easier way to level it out.

I'm assuming you have an '03 GT. In that case, you will need 3.2-3.8 quarts of ATF that either meets or exceeds the MERCON specs.

I use Royal purple Max ATF in my T-45 and it shifts like butter. Before that I had Mobil 1 synthetic ATF, which was also very good.

RP FAQ on their site says you can use MAX ATF or their Synchromax for Mercon spec. You could give their customer service a call and see what the difference is, but either one is fine. Their tech was pretty good the one time I called.

Having said that I use Ford Mercon ATF in my T-45...its cheap and works. I've been thinking about going to RP for smoother shifting from 1-2 during normal driving. However, I heard from a reliable source that the cheap stuff was better at high RPM shifting...who knows. Mercon ATF has gotten me to 102k with no problems.
