might this be a torque converter problem?
at lower speeds, 30-40 mph, i can release the gas pedal and the truck begins to slow, and then it will seem as though the engine just disengages and goes to a complete idle and then if i give it gas the whole thing re engages. then today, in that same speed range, the truck started acting as though it were shuddering or shifting gears, but i didn't notice the motor speeding up when it was doing that. and the problem is completely random. i could power my way out of it or if i just steadily gas on it it wouldn't do it, just a steady speed or very lightly increasing speed.
i just changed the transmission fluid about a month ago. this problem existed before the fluid change(the motor feeling as though it were disengaging). i had hoped it would take care of the problem, but not so. i also drained the torque converter at the fluid change. the fluid level is full and looks clear and clean and does not smell burned. i used mercon v which was the recommended replacement fluid. the transmission is a auto 3 speed c6. when i pulled the xmission pan, there was a gray residue which i wiped out when i cleaned the pan.
thanks in advance!

The shudder sounds like the same thing I had going on in my old truck. It was the torque converter. I drove mine like that for about a year that way and it kept running. I eventually sold the truck and I see it driving around town still. No clue if it was ever fixed.

thanks. the more i think about it the more i realize that it really jerked the truck. today is the first time it has done that. someone else suggested the modulator could be bad. i pulled the vacuum hose loose from it and a small amount of transmission fluid came out of the vacuum hose indicating a bad diaphragm. it may not totally fix my problem, may be more than one problem going on here but at least i know for a fact the modulator valve should not have fluid in it. that will be one problem out of the way and with any luck, my entire problem solved.
