I used dex/merc think it's 3.3qts. Think another good one is synchromesh? Just don't use royal purple.

IIRC the 3650 is only supposed to take 3 qts- they had a TSB on it but I could be mixing up the numbers...OP what year is your car?

I have a t45 so mine was 3.3. Just fill it until it comes out the full
Hole. Then you'll know you have enough. I leave the plug open, and pour fluid into the shifter.

This. But I left the fill hole opened and used a cheap fluid pump from Autozone and used the fill hole. Once it pours out the fill hole, put the plug back in.

I used Pennzoil Syncromesh.

If you have a 3650 def use Mobil1 full synthetic atf. 3qts exactly no more. Car will shift like butter. dramatic difference over wats in their now im sure

Additives in the RP eat away at the friction lining on the blocker rings. If you have a rebuilt 3650 with the carbon lining on the blocker rings, you are fine to run RP

I did the ol' "Secret Sauce" in mine last time I did it with the Pennzoil Synchromesh, and the Lucas Oil stabilizer. Still shifts great. Probably the only Pennzoil product I'll ever use.

From all the research I did, the most popular results have always been Mobil1 synthetic ATF, Dexron III spec fluid, or syncromesh... When I called tremec multiple times and asked about syncromesh, the general answer I got was that it will eat away at the syncro material over time... so many people use it , so it still makes me wonder if it will in fact cause problems, and if so after how many miles... never could get a straight answer
