It's likely shot--cheapest to install a rebuilt.

The model for your vehicle?
That would be considered a "K" model because it's 4X4.
Your transmission?
That would be equipped with 4L60 or more likely a 4L60-E Automatic Transmission, previously known as a 700R4 but is now improved and electronically controlled.
