tr3650 fluid level??

[zx3focus]

just bought a t3650 for my 97 cobra. I am putting the fluid in and I wanted to know how much I am supposed to put in? I have seen andywhere between 3-4 quarts. I put 3.75 quarts in. I have also heard fill it till it runs out the hole. Anyone have a # I can go by? THANKS

Ok here goes...

Ford originally spec'd the fill level to 3.6liters.

Next Tremec was saying put in 3.2liters.

Later a TSB was released for the 3650 because of the grinding in 1-2 on cold starts. The fix was replacing some synchros and such and using a fill rate of 3.0liters.

In my opinion...you should try a fill of 3.2-3.4L. I would say that 3.75qt is just a bit too much - though it is within the original ford spec... I had a bit of a grind/roughness in 1/2 before switchint to 3.3L of Mobil 1 ATF last winter.

You should only use Mobil 1 ATF or equal, btw.

The key is the fluid more than the level.

OEM fill is Mobil1, and you'll get bad cold shifting with it.

Use Royal Purple Synchromax fluid and fill to the hole and it'll be fine.
