what rear end is this and what gears are in it?

 

look under the hood or in the glove box and it should say the factory gears/axle.

 

I found nothing

 

Go visit the dealer, have your VIN number handy, and have them print you off a build sheet. It will tell you what your truck came with from the factory. (except for that whole power rack and pinion steering thing.....)

 

Alright that sounds good btw the tranny shop that did my rebuild put in a brand new valve body and my problem was solved
