So you're saying that the truck feels like it goes into a lower gear or the Torque Converter unlocks when you're just trying to maintain constant speed? Is the OD light blinking or CEL on? What happens if you apply more throttle, does the TC lock up then?

od light isnt blinking and no cel... I guess im not familiar with what the TC unlocking would feel like. Its hard for me to describe other than to say what i did above... Would the TC locking lower my rpms as though it were shifting into a higher gear? that is what happens when i apply more throttle its like a shift but not quite as many rpms as that... sorry if im not making sense...

When the TC locks up it is more or less connecting the engine directly to the transmission. With it unlocked the engine drives the transmission but the TC allows them to be "uncoupled" because the fluid in the TC is what does the driving. What you should feel as you go up through the gears is the 1-2 upshift, the 2-3 upshift, then the TC lockup, then the 3-4(OD) upshift. You'll actually feel it kind of shift 4 times even though there are really only 3 gear changes because the TC locks between 3rd gear and overdrive. Does that make sense?
When the TC unlocks the engine kind of just free-wheels on deceleration and while it drives during acceleration, it isn't a direct connection. A locked TC feels more like a manual transmission.

yeah, so took it out on the highway today and 3 gear changes only. when i step on it it feels like another "shift" which from what i gather is the TC engaging??? Im assuming i need a new one? is that indicative of a new tranny as well... also could that affect my milage driving around town?

It's really tough to troubleshoot this kind of thing without seeing it in person. If it is dropping 800 RPM when you let off the throttle it sounds as though the T/C isn't locking. I think I would suggest taking it to a transmission shop and having them take a look at it. You could always have them diagnose it and then bounce their diagnosis off the rest of the guys here on the boards.
