We add the FFM in the Lightnings rear diff so that the clutch packs in the limited slip aren't hurt. So, I'm assuming the FFM in the MTX-75, some how helps the blocking rings... Originally posted by rkneeshaw3.0: Originally posted by todras: Originally posted by rkneeshaw3.0:
My point is, the only reason I'm seeing people use friction modifier is because people on the CEG recommended it. I haven't seen or heard of it in any of Fords documentation or recommendations for this transmission. If it was so great, why hasn't FORD recommended it in a TSB, or any official documentation?
Per Terry. Synth is good for helping 'cold shift' issues but does nothing to help the syncros which need friction to work, hence the friction mod additive.

I'm not putting friction modifier in my transmission until the explanations add up. Is XL-7 a magical friction modifer that ADDs friction instead of REDUCING friction?
The definition of what friction modifier does goes against the reasons for adding it. Why?
Maybe the same reason its not part of the TSB ford released for its ford honey. Maybe its the reason my syncros went bad when I did the Mobil 1 + FM cocktail. Maybe not. But I'm sticking to what the TSB from ford says in the meantime, and that is straight up Ford Honey, no other additives. And if were asked, I would recommend others do the same.

No. I ran M1 plus XL-3 for 80k. Tranny was still in great shape. Run M1 in the SHO and it was too slippery w/o the FM. 3rd gear would grind. Added a little FM and good to go.

helps them by reducing friction? Its also not the reason given for adding it to the MTX-75 in the first place. I'm no trasmission or lube expert (hell, I'm barely a noob), but this is straight up old-fashioned simple reason.

I don't think it reduces friction, I think it in fact does the opposite, so that the clutch packs (RWD, Limited Slip) and the Blocking rings in the MTX-75 can get that extra 'bite'...

Can you back that up with any reference materials? I googled for awhile and could not find ANYTHING that says it ADDs friction. Everything said it reduces friction.

This thread has gone from most worthwhile to most inconclusive evar! All I would like to know is what fluid to run that will prevent my 3rd gear syncros from destroying themselves a 3RD time in the future!  P.S. - warmonger, I'll PM you if I still decide to get rid of my MTL.

akrump, in my opinion, I think it would be safe to use exactly what Ford reccomends for their product: The Ford Honey, without friction modifier.
It makes sense to me that if Ford went through the trouble of actually producing a replacement fluid specifically for this application that they would have either recommended FM if it was necessary, or included it in the fluid formulation already. Since the TSB only states to use the Ford Honey straight up, thats what I'm going to do and I'm confident it is safe to do so.
MTL may be a great product for the MTX-75. It may not. You can avoid the whole issue and just use what Ford has recmomended IMO.

No I can't 'cause I'm wrong Ryan. I searched the NLOC boards and it says that it helps reduce friction as well. I was confuseded
