I preformed a shifter shaft seal change with the FMX in my 69 Mach 1 (in car). Unfortunately I unbolted the front band servo too far and dropped the band pawl out. I just now got it and the servo reinstalled. The trick is use a small telescopic flexible magnet (Lisle part # 66580) to attach to the side of the pawl and lay it on the side of the band drum, I was able to support the stem of the flexible magnet by laying it on the "H" pipe. I adjusted the pawl up and down until I was able to hook the servo cam onto the thick part of the slotted wedge pawl. Using this method it took me about 5 minutes to install it successfully w/o pulling the transmission. Make sure that you have a bright flash light, leave the band in it's retracted state do not attempt like I did (at first) to wire it in a stretched out fashion.
When rebuilding any Ford transmission, you should always replace the beville return spring in the forward clutch. Many times during the teardown of these transmission, I have found these springs broken. It is one of the weaknesses of Ford transmissions.
Friend, in the part where the spring-loaded piston is present, my box has a wavy disc, you would help me a lot in telling me if I no longer put it on since I have a problem with the reverse, could you tell me if I no longer put it on and I only put discs and pastes and I discard the wavy one please greetings from Mexico I await your answer
Thanks ! I modify this home made tool for the different transmissions I rebuild, Recently I modified it for an AOD tranny, so I can't tell you the specif for a FMX tranny Sorry !
How many quarts of transmission fluid including the torque converter(converter was drained as well). I hear it's 12 & a half. Is it the same amount as a C6 or does the MX take less?
Sorry for the late answers, i was in holiday. The FMX capacity is 11qts if the tranny was taken appart, but if you just change the filter, you approximately drain 4qts off the FMX
With a stock rebuild, will a FMX handle 500 hp ? Are all cores the same, or do some models have more front clutches or different servos ? Does anyone make a reverse pattern manual valve body ?
Thank you for making this video! I was wondering what kind of grease you are using to hold the needle bearings and thrust washers, a grease that dissolves in ATF?
I appreciate you making these videos free to view. Thanks! Also did you happen to have any difficulties with this rebuild? I'm about to tackle an FMX, and its my first time rebuilding a transmission.
watch the video "part 1" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ojbnAETIR54.html , it's the disassembly of the transmission, this vid "part 2" is the reassembly
