Which transmission

[tongy66086]

I have a 2001 Explorer Sport 4X4 and was going to buy the EPC solenoid.
I figure I'll change the filter while I'm doing this, but it is wanting to know if Ihave the 5R55E or the 4R70W transmission.
What is a quick and easy way to determine which transmission I have?
Thanks a million for your help.

5r55e

The 5R55E came with the V6. The 4R70W came with the V8.

Thanks a ton.
I feel better ordering parts now.
