Ford AOD TECH

The AOD transmission was produced from 1980-1993 and was used in a wide variety of Ford/Lincoln/Mercury cars and light trucks. The hydraulic pressure system is modulated through the use of a linkage or cable connected to the throttle plate, as opposed to the familiar vacuum modulator. The compound planetary gear train is similar to the earlier FMX. Its powerflow is also similar, except that in third gear, the input torque is split between two shafts. It is this very unique dual input shaft arrangement, from which Lentech Automatics has derived various altered powerflows. Realizing the potential of these altered powerflows and rugged geartrain ,this was the first transmission Lentech chose to pioneer.

Ford AODE/4R70W TECH

The AODE/4R70W transmission has been produced since 1992 and is used in a wide variety of Ford/Lincoln/Mercury cars and light trucks. The hydraulic pressure system is modulated through the use of a electronic pulse width modulated solenoid (EPC), as opposed to a cable or vacuum modulator. The compound planetary geartrain in the AODE is identical in construction and ratio to the AOD, while the 4R70W has a wide ratio gearset installed. Its powerflow is also similar, except that a torque convertor lockup clutch replaces the direct driven lockup from the AOD. Since it shares the compound planetary arrangement with the AOD, the same Lentech patented Reverse/Third powerflow can be applied in select models. ( Strip Terminator )
