The C3 design was succeeded by the A4LD 4-speed automatic during the mid-1980s and was in turn succeeded by the 4R44 and 4R55 4-speed automatics during the mid-1990s. The Bordeaux Automatic Transmission Plant's current products are the 5R44 and 5R55 5-speed automatic transmissions."

"The A4LD was the first Ford transmission to use an EEC-controlled torque converter lock-up clutch and later became the first to use electronic shift control (via a 3-4 shift solenoid). The French-built A4LD was created by adding overdrive to the front of the C-3 three-speed unit. The A4ld has a 2.47 first gear and a 0.75 overdrive."
