transmission and transfer case are broken

Hello,

There are many local salvage yards where you can possibly get a used transmission and transfer case. Of course, you can also check with your local Chevy dealer as well.

Here is a good website that has connection to various recycled/used parts:

The prices will vary depending on the condition.
Also, if you have it installed in a shop the cost will depend on their shop rate. On these trucks the typical labor time is 9 hours.

I have attached the transmission replacement procedure below for your reference.

Please let me know if you have any questions.
Thank you.
