Call the shop who did the repair and have them fix it you received a warranty

From the info given all I can suggest is checking the fluid level in the tranny and look for a red oil underneath the vehicle. Get a tow, probably dangerous to drive. Best to call the shop that did the repair.

Wow, what did you do to that truck to cause the tranny to go out on a 2008? If the new tranny was put in recently, take it back to the shop. If they won't fix it for free, take it somewhere else! Also, is the truck 4 wheel drive? If so, make sure it's turned off.
