Thinking of using this in my Focus with the MTX75 manual tranny. I read the old thread on here (searched) regarding the Ford fluid (honey) and the Terry Haines recommendations. What are all you other Focus owners using in your MTX75? I can get the RP for $13/quart locally.

I have a ZX2, not the same tranny as you. But he Ford honey sauce is reportedly great. Amsoil and Redline make superb tranny oils, as well. I am not a fan of RP anything. I'd use one of the other three I mentioned.

I have an MTX-75 that has had Syncromax in it for years. Works great. Much smoother shifting compared to OEM fluid. I'll be replacing it with the same in the somewhat-near-future. I paid about the same for it, too($13).

I have not used RP SM in your application but if it is compatible with your fluid needs it is an excellent product as are all of their fluids.

I have a 1996 Contour with the 5 sp manual MTX that originally spec'd ATF then in 2000 they spec'd the Ford "Gold" 75W-90 manual tranny fluid. I had the Ford Gold for a while, everything was fine. Went to replace it and several dealers didn't stock it and didn't want to order it unless I bought the entire case. From a Contour site I was a member of Royal Purple Synchromax was recommended as a good alternative. Been using it for several. It shifts just fine. And it has the EP & AW that this tranny needs. Plus I paid mail order $9/qt shipped versus $21/qt at the dealer for the "Gold", it lives up to it's name crzy. Whimsey

Just put Amsoil MTF in my Honda in place of Honda Genuine MTF. I must say it does shift smoother, even when cold.
