I have a 2001 F150 4.6l 4x4... what trans do I have or how do I tell ? From what I've researched it's a 4R70W... is that right ? I'm looking to buy the BM Racing Deep trans pan, that why I'm asking.

 

Open the driver's door and look inside the doorjamb under the locking mechanism thingy. There should be a sticker with all kinds of information including a letter signifying the trans code -

Here is some basic information about Transmission types (somewhat unedited, but basically accurate)

Hmmm, that looks familiar...

4.6L for sure has the 4R70w in '01.
