i have a FMX tranny for my mav. the tranny is 2 inch longer then the stock braket should i use it or sell it. Is there a braket i can buy. i would like to put a stall converter in it. is c6 the same as FMX
No. FMX= iron case= super heavy Performance parts are expensive if you can find. Another vote for 'get a C4'! Dave
Fmx Up until the early 90's the C4 was a throw-away trans and people would use a FMX or C6 when running bigger engines (same for the 9-inch over a 8-inch rear). Once some suppliers worked out the weaker points of the C4 the FMX fell out of favor. I run an FMX, but it was installed back in 1989. You can't get all the upgrades I have in mine anymore either. Like Dave said, "Performance parts are expensive if you can find". Given a choice between the C4 and FMX, you'd be best with a C4, period. But, if you want to stick with the FMX... 1. You might need a longer drive shaft. The FMX is overall slightly shorter than a C4. 2. You'll need an offset trans mount. The mount is, like you said, set back an inch or so further than the C4's. Ford used offset mounts in other cars. It was a long time ago, but I believe I used the parts from a 1969 Cougar (351/FMX car). It had the offset trans mount and I also used its 9-inch rear. 3. The shifter... aftermarket shifters don't supply any brackets to hook the shifters up to a FMX. I fabricated mine and it was a pain to get it to work. I had to actually change the FMX linkage in the trans to get the proper orientation and drill a new hole, at the correct distance, so the detents in the shifter matched the detents in the trans (so P-R-N-D all matched up) 4. C4 should sound like a better choice, huh?
