Endorfin you need to look in your glove box there is a sticker in the back that tells you what you have.

 

UPDATE
I just come back from a fishing trip and am very impressed with my ride. It pulled my boat like a champ. I left od on and it pulled like it didn't have anything hooked to it. I think i have a hoss[8D] for pulling anything i want.

 

You might want to be careful with that od when towing it can make the tranny overheat.
