They came in three configurations: the small case (from 1951 to 1966) the medium case (from 1955 to 1968), and the FMX (from 1967 to 1979) Early Cruise-O-matics had a filler tube that attached to the transmission pan. FMX transmissions filler tube slid into the main case. The Cruise-O-Matic transmissions are easily identified by their design, which incorporates a cast-iron main case (unlike all other Ford three- speed automatic offerings) with separate aluminum bellhousings and extension housings bolted to it. The Cruise-O-Matics should be avoided in performance applications as very little is available in the way of aftermarket performance parts other than shift kits. The Cruise-O-Matics were also offered with all three bolt-common V8-pattern bellhousings. ====C4/C5==== *'''General Information''' **Bell housing: Aluminum ***Case fill: Attaches to case with 7 pump bolts ***Pan fill: Attaches to case with 5 bolts around outside of pump **Case: Aluminum; 11 pan bolts; 2 adjusting screws; 2 servos; Modulator (Except PEG-A build code) ***Case fill: Dipstick tube in case ***Pan fill: Dipstick tube in pan **Extension housing (2wd, Divorced 4x4): Aluminum; 6 bolts to case **Adapter housing (Married 4x4): 6 bolts to case ***C4: Cast iron ***C5: Aluminum **Front oil pump: 7 bolts to case **Input shaft ***24x24 spline (1964-1969) ***26x26 spline (1970 only) ***26x24 spline (1971-1986) ====C6==== *'''General Information''' **Bell housing: Integral ***Big block (351M, 460, etc): 7-11/16" top bolt centers, No cutout on bottom ***Diesel (426): 7-11/16" top bolt centers; Cutout on bottom ***FE block (330/360/390): Round with starter at about 9:00 ***Lincoln (460): 5-3/4" top bolt centers; Pointed top ***Lincoln (462): 5-1/4" top bolt centers; Pointed top ***Small block (302, 351W, etc): 5-1/8" top bolt centers **Case: Aluminum; 11 pan bolts; 1 adjusting screw; 1 servo; Modulator **Extension housing (2wd, Divorced 4x4): 6 bolts to case ***Aluminum ****7": Bearing; 0, 1, or 2 threaded bosses; With or without speedometer hole ****13-7/8": Bushing; With or without damper provision ****18": Bushing ***Cast Iron ****5-3/8": Bearing; Bolt-on cast iron speedometer housing ****13-3/4": Bushing; ****17-1/4": Bushing; Mount near case or near speedometer hole; With or without damper provision **Adapter housing (Married 4x4): 6 bolts to case ***Aluminum ****5-3/4": 0, 1, or 2 threaded bosses; 1 or 2 transfer case cutouts ****8-3/4" ***Cast iron ****5-3/4": 1 threaded boss; 1 or 2 transfer case cutouts ****8-3/4" **Front oil pump: 7 bolts to case **Input shaft ***31x31 splines (1966-1971) ***31x30 splines (1972-1996) ===Manual=== ==Mopar Transmissions== ===Automatic=== [[Image:Mopar_trans.jpg‎]] [[Image:Mopar_Automatic_A518_727_904.jpg‎]] A518/A618 (Left), A727 (Center), A500 (Right) ===Manual=== ==Other Transmissions== ===Automatic=== ===Manual=== ==Helpful Links== #[http://www.maliburacing.com/auto_tranny_id.htm GM Automatic Transmission Identification and Information]Very helpful identification guide with identification by pan and transmission dimensions. #[http://fiedlerh.home.att.net/BW.htm Borg Warner Second Design ST-10 4-Speed Info] Codes, applications a very informative page.
