Transmission Lookup



The name 4R44E means 4 forward gears, rear-drive platform (or 4WD, with a different tailshaft housing), rated for 440 ft/lb torque (after torque converter multiplication) and electronic shifting. 4R55E is the same but heavier duty and rated for 550 ft·lbs.

For the 1995 model year, the A4LD was upgraded to feature full electronic controls, resulting in a new transmission family. The two major versions of this new transmission were the 4R44E and 4R55E. In Europe, the 4R44E was known simply as the A4LDE (with the E referring to the electronic enhancements to the basic A4LD design) and was briefly used in the Ford Scorpio. The transmissions are fundamentally similar in design, varying only in the durability of key components based on the type of duty they were to be used for. The 4R44E was used in lighter-duty applications, namely with 4-cylinder or 3.0 L V6 models of the Ford Ranger pickup, while the 4R55E was used in heavier-duty applications, specifically with the 4.0 L Cologne V6 used in vehicles like the said Ford Ranger or Ford Explorer. The 4R55E was short-lived however as it was replaced in all instances where it was used with the newer 5R55E during the 1997 model year. The 4R44E continued on through the end of the 1990s before being replaced by the 5R55E's relative, the 5R44E.
