trans issue

so my truck runs awesome for the most part. shifts great pulls great, but when i stop at a red light or somthing, it will pull the idle down just below the line below 1000 rpm,i think its the 750 rpm line, like it isn't going into "nuetral", other times randomly it will be normal and idle between 1000 rpm and the line just down from it. any input appreciated.

nobody? it is like you letting out on the clutch in a 5 speed w/o letting off the brake....

It shouldn't go into neutral it should shift to first. Whats your idle set at? 1000 in gear at a stop is high in my opinion.

it's not at 1000, its about 800 i assume, i didn't say it goes into nuetral at a stop, it is supposed to drop the TC speed so that it doesnt try to pull at a stop, which kinda simulates nuetral, sorta. but the point is it isn't doing what its supposed to it is pulling down to like 600rpm or so instead of 800rpm and it starts loping and it can't be good for the trans, if i shift into neutral it will quit and idle at 800, so it is trans related,

For some reason it sound like the lock-up clutch is applying a little. Could be tcc solenoid issue, a problem with the valvebody or torque converter.

thats what i think, its what it seems like is the Tcc is locking too much, how would i test it to see if its the solenoid
