It is possible, but not easy. Both transmissions bolt right up to the 4.0L Cologne 60 degree V-6, and are virtually identical in size. The A4LD is a hydraulically-controlled transmission (mostly), and the 5R55E is fully electronic. So you need to get the controls for the 5R55E in there somehow. Some have swapped computers from the 5R55E truck, but there are some sensors in the rest of the truck that are different, so you will get some PCM errors. Some have created hybrid harnesses, and used both computers to control things. There are also aftermarket controllers ($$$). Google and read the Ranger and Explorer forums.
5R55E automatic transmission
The automatic transmission is an ( A4LD )
A4LD transmissions were installed in ford aerostars , rangers and explorers
4R55E-4 SPEED AUTOMATIC TRANS. 5R55E-5 SPEED AUTOMATIC TRANS. The difference is in the shift strategy that results in 5 speeds, most of the internal components are the same for both gearboxes. Valve bodies are different. Both are electronic, and both were installed primarily behind 4.0 liter 6-cyl engines, 5r55e is an improvement over the 4r44e which in turn owes its legacy to the c3/ a4ld of yesteryear.
How would i repair a 1993 ford explorer 4.0 liter A4LD Transmission?
Short answer NO. Long answer YES. The 5R55E transmission is the exact dimensions as the 4R55E transmission. 5R is a 5 speed, and 4R is a 4 speed. Though, as long as you don't swap the PCM on your Ford, it will stay a 4 speed.There are solenoids and sensors that are not the same, including the TCC (torque converter clutch) and a couple other things.If you are ready for your truck to be down a while, go for it.
