Torque Coverter not engaged properly was created by Rwtaylo14
Jumping straight to the point, I’m an idiot and installed the transmission without fully engaging the TC. Long story short I started the truck, heard a pop, and now I’m pretty sure the fluid pump and the TC are shot. My question now is can I drop the tranny and simply replace the pump and torque converter or does the entire tranny need to be rebuilt and cooling lines flushed?

I drive a 06 GMC Sierra 1500 with a 5.3 vortec and a 4l60e transmission

Grateful for any advise!

Tough one to call..
If all you did was start the engine and NOT try to go into gear..
You may be lucky ( if you can call it that ) that all you did was damage the pump and torque converter.
You'll be dropping the transmission no matter, so dropping the pan and a good inspection and perhaps pulling the main valve body just to be sure would be a reasonable course of action.
As to flushing the cooling lines ... it couldn't hurt.
