You may want to try changing the transmission fluid and loading only 3.0 L (3.2 qts) of fluid--I recommend Mobil 1 ATF.

There is a TSB describing the problem (TSB-04-26-13), which is that the factory and owner's manual recommendation of using 3.8 L (4.0 qts) is too much.

This caused windage problems, with the excess lube causing the gears to over-synchronize because the excess oil makes the fluid overheat and foam. This and affects the turning ratios of the gear train; similar to your trying to run on the beach in 2 feet of water. The increased resistance to turning slows the gears prematurely and alters the synchronizer timing, causing shift problems. The oil level was reduced to 3 liters and the problem was resolved.

Reducing the fluid level, and using the M1 ATF, can help or even correct the problem if no severe damage has been done...

Id swap a qrt of fluid for a qrt of syncromesh..it did help when i had that issue. But he is right 3.25 qrts is the correct amount.

Could be clutch. My friend had same problem and we thought it was synchrob but it was the clutch... Does it seems easy to push down, like no pressures to it?

If the revs are over 3k it wont go in and make vibration with grinding sound. If revs are under 3k is normal like nothing is wrong, i like shifting higher than 3k even when cruising it just sounds better and feels right

That is exactly the issue addressed in the TSB. There is a similar TSB (TSB 04-15-6) for the 2001 through 2003 model years...

They meet the same basic specification, however they do not perform the same--use the M1, you will not regret it...

Thanks for the info.

I saw a post about a 3650 that felt 'notchy.' Mine feels like that this year in the cold temps. After a little research I found several posts and articles about MERCON ATF. If ATF stands for automatic transmission fluid, it is difficult to understand why I would put that in my manual transmission rather than a gear lube. Some drivers suggest synthetic and others say don't use synthetic. My owners manual says to use MERCON, also. The TSB says to only put 3 liters in the gearbox. Id rather understand the instructions rather than just follow them, if you know what I mean. I was wondering if I missed something until I saw this particular post and then referenced the TSB.

Thanks for the M1 advice!

You would put ATF in your 3650 transmission because that is what Ford recommends, and more importantly because it is what Tremec--the company that manufactured the transmission--designed it to use.

This is from the Tremec 3650 service manual:

Lol.
I was just thinking about this thread but I've been too busy to go look for it.
I was at an autocross last weekend and thought I was going to grind second gear perfectly round before the day was through... Embarassing!... No, I still had not ever changed the transmission fluid since purchasing the car a year ago. I needed no further reminders. It was full of metal shavings (hope they weren't all mine!) and looked like it had never been changed. It was slightly over filled as well.
I refilled with 3.25 quarts of Mobil 1 synthetic, as Cliffy suggested, and it seems to have cured the problem.
It shifts noticeably smoother now...

My T-45 does this going from 1st to 2nd. Used to do it from 2nd to 3rd but fresh fluid cured that. Still, time for a new trans. I'm in KY right now but by the end of the month a fresh 3650 is going in with 3.2qts of Syncrhomesh.

Another thing to look at is your shifter. No joke, if you have an aftermarket shifter in there from a previous owner and he/she set the stops (or you did) that is a very bad thing in a 3650. The 3650 has internal stops and you do NOT use shifter stops. Doing so can potentially cause it to not engage into gear fully. The second hand 3650 Tri-Ax I got to put in my new trans has stops and they are definitely set. I'm just removing them before it even goes near the trans...

I was going to make a thread on this but I will just hijack this..

Mine grinds from first to second, but only when it's cold. When my trans warms up it shifts nicely. My trans also clunks when going into first. Clutch will need replaced prolly in 15-30k miles, but it shouldn't be my clutch. I planned on swapping fluid out this weekend with Mobil1 ATF synthetic to see if it will correct my problem or at least make it a little better. Where do I grab this fluid at?

Any box store sells it or just order it online. You have a typical 3650 issue and likely is the fluid being overfilled from the factory spec or the owners manual being followed by a previous owner. 3.2 qts is the correct amount.
