2023 FMX TRANSMISSION INFORMATION

as far as parts available it's true there really isn't much. catalog / shelf stock TQ converters if you're lucky and a couple shift kits but that's OK. any real transmission builder worth his salt can build an FMX to provide clean crisp shifts and last another 1/2 century. all the basic principals apply, slightly increase pump / line pressure, reduce accumulator spring pressure and recalibrate the valve body with the shift kit. you can drill the drums for lightening or just to allow oil to escape, remove the wave and add a clutch or 2. coincidentally the FMX and AOD share the same size clutches & steels so modern materials are available. Kolene, Kevlar, Red Alto clutches, Raybestos Blue Plate clutches all kinds of modern goodies available in various thicknesses so the builder can build a custom clutch pack

1st step is to find out if your FMX is a candidate to be rebuilt, a good report card on the condition of your hard parts is pretty important as replacements are hard to find these days. then there's the other side of the coin some guys can't give away a complete 'worked when pulled' FMX
