Contour Enthusiasts Group Archives Forums General Troubleshooting Friction Modifier question

Is there more than 1 type of the fm for the tranny cocktail? Stopped by the dealer to pick some up while in the area but I did not have the part number supplied in the FAQ section. The tech at the parts counter was cluless as to why I would want to put it in a 99 SE MTX. Basically I want to be sure I have the right stuff

Motorcraft Additive Friction Modifier
4oz bottle
closest thing to a part number on the back is XL-3 Ford Internal Ref No. 137219, says it is used for limited slip diff. Do I have the correct fm?

Thx for help in advance

Hi,

This is whats posted in the FAQ section "Tranny Problems"

-Bottle of Ford Friction Modifier C8AZ-19B546-A (you will only use half)

...Ed

Is this what I have? Can't find that number anywhere on the bottle

You have the right stuff. Ford has been changing the part numbering system on it's chemicals lately. It's prime use is on limited slip differentials.

Thanks
