Tr3650 fluids with Aluminum flywheels

[o2sys]

So due to the lighter aluminum flywheel I have noise during idle which is liveable but what I can't live with is during low gears the gear lash or whatever noise it makes often described as "marbles grinding" or "coffee grinder" is just a plain awful.

I currently have the original mercon atf that ford put during assembly. And based on this article, a thicker blend of atf can help?

I have the same rattle. I have spec II with alum flywheel on stock 3650... drives me crazy.... New throw out bearing too...

Yea I have the McLeod aluminum fw, rxt clutch kit. It has a new pilot bearing and throw out as well.

Try Pennzoil Syncromesh.

A twin disc will have floater plate rattle. On a McLeod it's usually right around 1700 rpms and most pronounced in 4th gear.

I just have it at idle; push clutch in and it goes away. Would a heavier weight oil help?I have to look into Penzoil synchromesh

Penzoil synchromesh did wonders for my 3650

Another vote for the synchromesh...I switched to that when I still had my 3650 in the car per tremec's recommendation after emailing back and forth with them. Trans will be a little more notchy until it warms up with it so just take it easy on it while it's cold.

What, Syncromesh? My Ford certified mechanic has been using Syncromesh in Ford manual transmissions for 20 years. Tremec recommended Syncromesh in their transmissions until very recently, when they switched to recommending Mobil1 synthetic ATF. I've run both Syncromesh and Mobil1 synthetic ATF in my transmissions (plural, more than one) and Syncromesh has a much better feel to it.

Just the pretense of removing noise from the flywheel and clutch floater plate.
