I have a '97 F-150 4x4, 4.6L, automatic. I was under the impression that there were 2 different automatics. Can you tell me what the 2 are, and any identifying characteristics of each?

Thanks

You have the 4R70W.

 

The 5.4 for 97 has the E4OD.

 

Any easy way to distinguish the two?

yes........look on your door Jam for the lable that has the vin # (driver side) if it has a "u" under the TR column it is a 4R70W if it is an "E" it is the E40D.
