All Tr3650 Owners Read This!

scp616 · September 14th, 2009, 06:39 PM

To clear up some controversy...
After talking directly to tremec I have learned several very important thing about the 3650

--> Only put 3 Liters of Chevy syncromesh fluid in (penzoil also has synromesh fluid that works)

This comes directly from speaking with an engineer AT TREMEC who says that after doing extensive testing, it is the best fluid to use REGARDLESS OF ANYONE TELLING YOU THAT THIS WILL NOT WORK WITH THE SYNCHRONIZERS PROPERLY

They also found that the reason the 3650 feels notchy during 1-2 and 2-3 shifts is because of the factory recommended 3.8 liters. This additional .8 liters raises the fluid level high enough that when the gear is moving for engagement, it is slowed down by the drag of the fluid decelerating it enough to not properly engage the next gear.

sooo.... use 3.0 liters of Penzoil Synchromesh fluid for a drastically better shifting and longer lasting transmission

hope this helps some gear jammers out there, it's been bothering me for a longggg time

All Data says 3.3qts of Mercon V. That's what I use. No problems ever what so ever.

scp616 · September 14th, 2009, 06:56 PM

I put that in when i got the car, it GREATLY helped the problem, the 3.0 quarts of synchromesh made an even bigger difference
Just got off the phone with TREMEC after calling about the kit i posted about earlier, and that's how the discussion started

SteviGX · September 14th, 2009, 07:43 PM

dont put over 3 in IMO...my trans is FUBAR'd because of it. jamming gears with that much fluid shaved my syncro...yay for the 700$ mistake!

This is hardly news, Ford's TSB 04-15-6 from 2004 recommends 3.0L (3.2 qts) of fluid for the TR-3650.

I think you can put it in through the top can't you? It was a PITA putting it in through the fill hole underneath with those small little hand pumps..... please someone tell me I can.

scp616 · September 15th, 2009, 02:02 PM

Yeah u can put it in through the top
i got this pump thing from northern that sucks the old out and pumps the new in,
Best $100 i ever spent, i use that thing for everything lol
So i actually used the fill hole, but last time i changed the fluid i poured it in through the top, and i didn't have any problems

huggy bear · September 15th, 2009, 02:47 PM

how many miles should you be changing your tranny fluid?? so 3L(3.2qrts) is all you need?? Chevy syncromesh???

TorqueO · September 15th, 2009, 04:16 PM

Just wondering ...why not just use Royal Purple Synchromax or ATF?
