727 HISTORY IN BRIEF.

A488

The original Torqueflite was designated A488, with a cast iron case and no parking pawl.

A727

The A488 was replaced in 1962 with the A727 (later 36RH and 37RH), with an aluminum case to reduce weight by about 60 lb (27 kg). The A727 incorporated a  parking pawl and various internal improvements, and used a 10.75 in (27.3 cm), or 11.75in (29.8¬ cm) torque converter. The heavier-duty A727 Torqueflites became  - and remains - popular for drag racing and monster truck applications because of their controllability and strength.

In 1978, most Torqueflite transmissions gained a lockup torque converter clutch to mechanically connect the converter's impeller and turbine, eliminating slip for better highway fuel economy. This addition required the removal of the torque converter drain plug.

Torqueflite was an available option or standard equipment, depending on model and year, on all Chrysler products: Plymouth, Dodge, DeSoto, Chrysler and Imperial. It was also used by American Motors beginning in 1972, where it was named Torque Command, as well as by Jeep, International Harvester ,Maserati Quattroporte, Monteverdi and Bristol, Aston Martin, and Jensen in the UK , as well as several brands of light and medium-duty trucks and panel vans. When installed in Dodge trucks and vans, the transmission was marketed as LoadFlite.                 

Also Range Rover Classic’s used the Torqueflite form late 1982 to 1985. That version was based on the International Harvester main case.
