The 4R55E has a higher torque rating than the 4R44E. There might be some internal differences. I'm only familiar with the differences on the A4LD which is used on the 3.0L compared to the 4.0L. They have a different bell housing, torque converter, rear snap ring, rear shaft, check ball configuration, and possibly other differences. I'm sure that the 4R44E has other minor differences compared to the 4R55E.

so what did you do JImbo?
I am in the same situation, and I am ordering the green epc, since I ordered a red one incorrectly .
I have a 96 Explorer 4.0 with a T code, which would indicate it is a 4r55e.

Did you put the red epc in?

They made their specs somewhere around the style of the red band model, but if they say that it will work in both, then it should. They engineered their product a certain way. There was an upgraded solenoid after they came out with this one that they sent some testers if they requested it.

Is there any truth to the trans (4R44E) tuning tip that turning the EPC Solenoid clockwise 1/4 turn makes it shift firmer?

Don't play with the set screw adjustment. You might throw off the pressure setting, and make it worse. This is a high wear component, so the best course of action is to replace it if it's defective. Did you check the EPC pressure with a 0 - 300 PSI test guage?
