vans. When installed in Dodge trucks and vans, the transmission was marketed as LoadFlite. In the 1990s, the transmissions were renamed, however the original Torqueflite design remained the basis of many Chrysler designed (and built) transmissions through 2007 (and FWD transaxles through 2000). Nomenclature Torqueflite transmissions and transaxles made through 1991 were assigned arbitrary engineering designations consisting of the letter "A" followed by three digits. 1992 and later units have four-character designations in which the first through fourth characters indicate, respectively, the number of forward speeds, torque capacity, drive type or transaxle orientation, and control system: Rear-wheel drive transmissions A466 The original TorqueFlite was designated A466, with a cast iron case, separate iron converter housing, and no parking pawl. A727 (36RH/37RH) The A466 was replaced in 1962 with the A727 (later renamed 36RH and 37RH), with a one-piece aluminum case to reduce weight by about . This was initially referred to in consumer-oriented publications as the "TorqueFlite 8" to differentiate it from the A904. The A727 incorporated a parking pawl, with the sole exception of the 1962 Chrysler and Dodge 880 version, which had an extension-mounted drum brake. Compared to the early cast-iron transmissions, many and various internal improvements were featured, and it used a or torque converter. The heavier-duty A727 Torqueflites became — and remain — wildly popular for drag racing, off roading, and monster truck applications because of their controllability, reliability, ease/cheapness of repair and brute strength. Note there are unique bellhousing bolt patterns for the small block "A" and big block "B" engine versions of this transmission, and for the AMC/Jeep applications. 1962-1978 361, 383, 400 B-Motor V8 1962-1978 413, 426 Wedge, 440 RB-V8 1966-1971 426 "Street" Hemi 1964-1971 426 Race Hemi (super stock, etc.) 1962-1966 318 "A" "Poly" V8 1968-1973 340 (all) 1969-1983 225 (Police, Taxi) 1971-1980 360 (4-BBl only) 1978-1983 318 (4-bbl Police) 1972-1978 AMC "Torque-Command" 1984-1989 318 (2-bbl Taxi special order) 1980-1991 Jeep (some) Gear ratios: A518 (46RH/46RE) The A518, later renamed 46RH (hydraulic controlled governor pressure) and 46RE (electronic controlled governor pressure), is an A727 derivative with overdrive, in the A500 ilk. Starting in 1990, it was used in some trucks and vans. The overdrive fourth gear ratio is 0.69:1.
