In my '73 Torino wagon there is a problem with the FMX transmission. - No Reverse. All was working very well the last two years, but this week I parked the car, in reverse!, and the next day the reverse slipped. Just a littlebit more than idle would cause the reverse gear to slip. I checked the fluid, and added 1/4 liter. It made no difference. I drove the car out of the garage, and I selected Reverse....Nothing happened. P,N,R... No difference. Thinking about it... Past month I noticed maybe twice a slow shifting from second to third... Today I'll try if the transmission will shift properly from 1 to 3, I'm not shure about this at this moment. Maybe important to know, so one can tell something about the cause, and what can I do to solve this problem. - Just came back from a testdrive, and I found out that upshifting and kickdown are working fine. (3->2 and 2->1) But.. manually shifting to first gear at 30 MPH: the car freewheels; it won't slowdown, the engine idles. In second it does slowdown by the engine. I could use all the tips and experiences of you all. Is there someone who recognizes this problem? Please let me know !!

too bad you're in holland, Or you could have the spare FMX in my shed for free. my car has an fmx, and its been indestructable so far. They do have band adjustments on the outside of the case, if they have never been adjusted, that may help. ------------- -Pete 1972 montego GT 1970 Torino cobra SCJ 1970 mustang mach 1 1965 Falcon futura |

Thanks for your reply AND your offer ! It's too bad indeed.. (Aaarrghh...!) I will remove the oilpan saturday morning and see what I can find. Rear and front band adjusting might help, I'll try it an see what's happening. Someone said those FMX's are strong like an ox, but sensitive to dirt and/or sludge. Anyway, I'll give it a try.

Yes, give it a try.. Hopefully new fluids, fresh fluid filter and band adjustments help.
Dirty fluid filter alone can really make FMX to slip or hesitate.
In case you happen to need instructions, here´s some: (Copied from Ford muscle site)
FMX Transmission
FRONT BAND ADJUSTMENT When it is necessary to adjust the front band of the transmission, perform the following procedure:
Special band adjusting wrenches are recommended to do this operation correctly and quickly.
REAR BAND ADJUSTMENT
The rear band of the FMX transmission may be adjusted by any of the methods given below. On most cars, the basic external band adjustment is satisfactory. The internal band adjustment procedure may be done when the external adjustment procedure cannot be done correctly. On certain cars with a console floor shift, the entire console, shift lever and linkage will have to be removed to gain access to the rear band external adjusting screw. REAR BAND EXTERNAL ADJUSTMENT The procedure for adjusting the rear band externally is as follows:
The adjusting screw is located on the upper right side of the transmission case. Access is often through a hole in the front floor to the right of center under the carpet.

Thanks for your replies, we found the cause of the problem! This is what we saw after taking off the pan. A problem with the rear servo.  So we took out the servo. You see the piston, and a blown away O-ring.  But looking again, and closer, there's something missing from the rear band !! The side of the band driven by the servo was broken off ! (right band side)  This is the broken off piece of the rear band. The light grey part is the broken surface. Metal fatigue ?! So I'll have to replace the band and adjust it, and fix the rear servo. Could have been worse!! Next week I'm on the road again. ------------- Gran Torino'73 Wagon, 351c, Goldglow, sportsmirrors, sportscluster, cold airc., Bi-fuel: Petrol+Propane(LPG), Pertronix ignitor1, 2 Oxygen Sensors and a daily driver ! |
