Chrysler A727 TorqueFlite Transmission Guide: Years, ID & Parts
Chrysler A727 TorqueFlite (TF-8) 3-speed automatic | later called 36RH / 37RH
The A727 is Chrysler's heavy-duty 3-speed TorqueFlite. It went into production for 1962 and was used behind Chrysler, Dodge and Plymouth rear-drive V8s, in Dodge trucks and vans, and in AMC, Jeep and International Harvester vehicles. In the early 1990s Chrysler renamed it the 36RH and 37RH. The design did not change with the name. Later, Chrysler added an overdrive unit to the A727 to make the A518 (46RH).

A727 or A904? How to Tell Them Apart
The A904 family (TF-6; A904/A998/A999, later 30RH/31RH/32RH) is the lighter-duty TorqueFlite. Many A904 and A727 parts look alike but do not interchange, so check which one you have before ordering.
| Check | A727 (TF-8) | A904 (TF-6) |
|---|---|---|
| Oil pan shape | Irregular outline with a bulge on one side. It is the same pan outline as the A518/A618. | Nearly rectangular with one cut corner. It is the same pan outline as the A500. |
| Pan gasket we sell | OEM # 2464324 (cork, Farpak or molded rubber) | OEM # 4295875 |
| Pan bolt count | Both have 14 pan bolts, so the bolt count will not tell you which one you have. Use the pan outline. | |
| Bellhousing | Both have the bellhousing cast into the case. Small-block Chrysler, big-block Chrysler and AMC/Jeep engines each need their own case, so a case from one engine family will not bolt to another. | |
If the pan looks like an A727 pan but the unit has a separate overdrive housing behind the main case, it is an A518 or A618. See our A518 / A618 / 48RE guide and the A500 vs A518/A618 pan, filter and solenoid guide.
Early vs Late A727: Which Parts Fit
The A727 changed several times over its life. Know the model year before ordering kits, bushings and converters.
| Years | What changed | What it means when ordering |
|---|---|---|
| 1962–1964 | Push-button shift on the dash | Shift linkage parts are year-specific. |
| 1962–1965 | Flange-style output | 1966 and later use a splined output shaft with a slip yoke. |
| 1962–1970 | Early front clutch and reaction shaft | 1962–1970 gasket & seal overhaul kit |
| 1971–1993 | Wider front clutch and reaction shaft bushing, from about 1971 | 1971–1993 overhaul kit and 1971–1993 bushing kit |
| 1978 on | Lock-up torque converter | Lock-up and non-lock-up converters are not interchangeable. Match the converter to your unit. |
| 1994–1999 | Late 36RH/37RH truck and van units | 1994–1999 overhaul kit |
