Friction modifiers or antifoam who's FOS?

[Gary Allan]

Hockey (Okay, if said with a heavy foreign accent)


Not too long ago some of the board members stated that they added "anti-foam" to regular AFT to make it suitable for the Chrysler/Mopar 7176 spec. This challenged my source on the matter, which was a trans rebuilder. The rebuilder used bulk AFT and added what he called "friction modifier" to the fluid. This made sense. Also one non-company sponsored Mopar site dealing with their automatics stated that if the wrong fluid was used .."micro-grabs" would occur in the close tollerance overdrives. Converter clutch chatter was also mentioned as a side effect. Neither of these sources mentioned 'ant-foam" or "foamation' as a cause or remedy.

Neither have any sites that I've visited including Redline's (site sponsor). The ATF C+ mentions "modified friction" including this one Chrysler 7176 and several varieties of Chrysler ATF-Plus. All are "friction-modified" lubricants

Now the two members (I forget who) ..referred to "anti-foam" as though it was the most common of knowledge and nomenclature in the industry.

Yet I have yet to see ONE referrence to it in an authoritative source.

Can someone say "Oh ..yeah, the MOPAR stuff in the bottle IS a friciton modifier AND antifoam".

or ...

"...Everyone knows that this is an anti-foaming agent that is also a fricition modifier.

Reason? I have a decent stock of Mobil 1 ATF. At the time (and as far as I know now) they did not have 7176 fluid available in the synthetic. I want to use this fluid to change over my 30RH (904/909/999) in my Jeep and want to know REALLY what the story is.

Ahhh ...the thread Do you see my cofusion?

Lubegard black bottle says it supplements DexronIII ATF to meet D-C requirements.

I think the antifoam guys have inhaled too much beer foam.

Whoa, GA, don't get your shorts in a bind.

What Ken said.

All ATF fluids already have sufficient foam inhibitors to take care of foaming. Some foam inhibitors are made from silicon materials and some are made from special hydrocarbons called methacrylates.

The LubeGuard Black is advertised as having special ester friction modifiers to convert Dexron III/Mercon's to DC ATF+4.

Lubegard is cheaper around here. Their competitor definitely needs to lower their price.
