Ford-O-matic/Cruise-O-Matic/Merc-O-Matic Introduced in 1950 as a Ford-O-Matic became Cruise-O-Matic in 58. The original Cruise-O-Matics used a torque converter and planetary gearsets, giving three forward speeds plus reverse. In some applications, Ford offered a dual-range option allowing the driver to start in either first gear or second gear.
MX/FX The original versions, known internally as MX (larger) and FX (smaller).
FMX An improved version called FMX, which used stronger MX-type rotating parts in the smaller FX case; introduced in 1968 and built until 1982. The FMX used a Ravineaux planetary gearset.
C3 The light duty C3, introduced in the 1970s and built in France at the Bourdeaux Transmission Plant. The C3 was a light duty version of the C4 design. Rectangular pan w/13-15 bolts.Can also have a slight bulge on front passenger side. Strictly light duty applications. Shift pattern = P-R-N-D-2-1

AOD - Intregal bellhousing and transmission. Not electronically controlled. 20.5” overall length. Good, medium duty 4 speed OD tranny. Rectangular pan like C4 but both rear corners angled slightly. 14 bolts on pan. When mated with 2.73-1 diff., speedo gear tends to be 8 tooth, otherwise 7 tooth. Came with wide and std gear ratios. V6 version lighter duty than V8 version. Has 1 electrical connector to neutral safety switch. Uses TV (throttle valve) linkage and cable on left side to carb/throttle body. Proper TV adjustment is CRITICAL. Pre-88 models lack rear-lube enhancement. 92-93 E and F series trucks have the stronger version of AOD available. Most Lincolns and some trucks use a 1 inch longer output shaft than the Mustangs and other vehicles. Overall length 30 1/4 inches. Shift pattern = P-R-N-OD-D-1.

AODE - mainly intended for the new Modular V8 at first, but it was also adapted to the old AOD bell-housing for vehicles still powered by OHV engines. An electronic/computer controlled AOD but with other improvements as well. - - Came with wide and std gear ratios. Through 1995, same ratios as AOD, except 94-95 T-bird 94-95 F and E series trucks, - 95 full sized cars and 93-95 Linc.Mark VIII. 1996 and later are all wide ratio. 1992 only cars have AOD shift pattern (as above) with no OD cancel switch, otherwise shift pattern = P-R-N-OD-2-1 V6 equipped AODEs have one less clutch plate than V8 models.Can be modified to add the extra clutch plate. Some trucks and possibly Lincolns have a 1 inch longer output shaft than Mustangs and other vehicles. Some have larger output bushing. Casting mark = F3LP or F3UP. - The smaller std bushing version has casting marks F2TP or E0AP - Has more than one wire connecting to it versus AOD with only one. Has OD button on end of gear selector. Various different bellhousing patterns used.

4R70W - A revised version of the AODE. T4R70W stands for gears, Rearwheeldrive, 70x10=700 Nm load capacity and Wide gear ratio. It has lower 1st and 2nd gear ratios for better take-off acceleration and improved gearset strength. On vehicles powered by a 5.4 L V8, a stronger gearset is used than in normal duty 4R70Ws. This tranny is computer controlled. Pan length just under 15”. New and improved AODE. Wide ratio AODE w different output shaft. Avoid the version used on V6s. A 20,000+ GVW cooler is highly recommended with or without a shift kit. Breakdown of the friction modifier in the fluid often results in convertor shudder (feels like driving over rumble strips) where convertor tries to lock up, but slips.

Electronically controlled. 94-up trucks w/ overdrive cancel switch and P-R-N-OD-2-1 can be E40D Pan length approx. 20”. Overall tranny length 37 1/2”. 95 up units are better.
