As I pulled out on the highway of that pop in my transmission. I drive a 2007 Chevrolet avalanche 5.3 L V8. Truck seems to be stuck in neutral when placed in "Drive" nothing happens. I can cycle through first second and third gear manually and reverse works but in "D" Nothing happens.

you should take your truck to a transmission shop. you may have a bad forward sprag assembly. there is a tsb from GM: 08-07-30-027, issued June 04, 2008. 1st 2nd and reverse work but drive or overdrive won't work.

basically they will usually be recommended that you rebuild your tranny.
