What's the difference in transmissions?

This is directly from the ATSG Manual.

The Ford 5R55S and 5R55W transmissions are both very similiar in design to the Ford 5R55N transmission and use electronic shift controls. The 5R55s/5R55w are both "Syncrounous" units, as they do not use the intermediate clutch and intermediate sprag that the 5R55N incorporates. The Ford 5R55S and 5R55W transmissions were introduced in 2002, found in the Ford Explorer and Mercury Mountaineer vehicles, and are available in both 2WD and 4WD configurations. For model year 2003 they are also in the Lincoln LS, Lincoln Aviator and Ford Thunderbird. They are designed for operation in longitudinal powertrains for rear wheel drive vehicles.

5R55S Gear Ratios 5R55W Gear Ratios
1st Gear 3.22 3.22
2nd Gear 2.29 2.41
3rd Gear 1.54 1.54
4th Gear 1.00 1.00
5th Gear 0.71 0.75
Reverse 3.07 3.07

I don't have any information on 5R55E transmission.
Hope this answers your question.

The 5R55E has a separate bell housing, and a dipstick fill tube unlike the other 3 models. The other 3 have no dipstick fill tube, a unitary (one piece) case design, and 2 large servos on the passenger's side.
