    Help as a former chevy guy i need some direction from a ford transmission expert. My 41 ford has a 3 speed FMX transmission. I had it rebuilt last year and everything was fine. When it sat over the winter i noticed a puddle of trans fluid under it.:confused: I tightened up the bolts on the pan and the leak slowed some what. kept checking the fluid and drove it a couple of weekend to local shows till I could get it back to shop that did tranny. On sunday went to local show everything was fine came home and went to back up no reverse.:eek: Did I screw up my tranny? I can't have a 1000 miles since it was rebuilt. Its going back to shop tomorrow.

    Also if I want to change to a different trans what would be the same size? With the X frame there is not much room to work with.
    Thanks for any input

    First off what motor is in front of the trans. If its a SBF a C4 would work. You may have to move the trans mount and change the drive shaft.

    The FMX is a good trans but they need to be full. If not reverse is the first to not work. Check the trans fluid after it warm and been shifted through the gears a few times.

    I had a 351 with a C4 in my 41 Ford. The trans fit the stock X member with out any problems. The C4 is not as wide as the FMX and has a shorter trans pan.

    I used to have a Torino with the FMX. Not having reverse was it's way of saying it needed the fluid topped up.
