Slippage is normally described as when then engine revs up but the
vehicle does not accelerate until the bands lock on the drums, so you
dont move or move any faster until the slippage stops. Slippage at idle
is normally described as the thing bangs hard into gear (after the motor
revved to 3grand). Slippage is normally felt at gear change intervals
and when taking off from a dead stop. Most often, torque converter
problems are felt at times when you are driving in a certain gear, and
it feels like the engine has a missfire as the torque multiplication
action of the converter changes. It can feel like a bucking or a
surging.
Slipping can be a function of low fluid level. Check the level as
described in the owners manual, also the dipstick may have info like
"check hot in park" etc. Put the proper fluid in the truck. Check the
trans for leaks at the pan, output seal, front pump seal, and anywhere
else. Other reasons for slipping can be worn bands and low fluid
pressure internally, now your talking an overhaul.
The converter stuff is a little harder, and many times will result in
a code being thrown. It may not necessarily be a bad converter, but the
lockup function can be malfunctioning due to a bad tcc relay.
