bad lope/surging at idle

[Drumman]

hey guys my truck(in sig) has a wierd lope/surge at idle. the truck has been sitting for about 3 months waiting on a new trans. monday i start it up just to get things moving and lubricated. started up fine no problem let it get warm and then shut it off. wednesday day i go out and start it and it has this bad lope at idle, starts up fine just idles bad(watch the video). i did take the tranny out on tuesday so i was wondering if the speed senor on the tranny would have anything to do with it or any other senor. i have looked over the whole truck, no sensors are unplugged(except for the trans sensors) im getting 15psi of fuel at all times and it does it with the quad on or off the truck. just wanted to see what you guys think, i have codes being thrown for all the tranny sensors on the dash, im about to go out with my scanner and see if i can pull anymore. any ideas on what coud be wrong would be great

Not just to be a prick, but why not wait 'til the tranny is back in? Sounds like a study in futility.

yes i can wait till the tranny is back in to see if that way the problem but its kinda like i want to figure this out now though if its something else

my truck sounded the same way with no tranny in it. must just be the motor has no weight to spin. not to sure
