97 transmission problems

SHORT VERSION (LONG VERSION BELOW):

1997 Suburban
2 WD
104k

problem:

press the gas to go, i get high revs and the truck creeps...

LONG VERSION

the other day i noticed a weird lugging feeling in traffic after about 20 minutes in stop and go traffic. the truck was kinda jerky from a complete or slow role. i pulled back in to my office building and came back to the truck about 6 hours later.

drove the truck home and no problems.. (35 miles)

went for a drive today... cold morning no problems for atleast 40 or so miles...
all at mainly highway speeds. hit a traffic light. pressed the gas on green. high RPM's and the trucked just creeped. made it to a parking lot. when shifting to drive or reverse i dont feel any "load" on the transmission. just high RPM's and slow go. came back to the truck about 4 hours later. pulled of fine, did the rev thing again. this time i noticed a slight kind of grindy noise. i parked the truck and came home.

think it could be a torque convertor or maybe the computers trying to compensate for something else?

thanks in advance for the help

Really sounds like a converter problem,,,when you lose ALL movement,,,,
If you pull the trans pan,,and find nothing,,,,It's usually the converter///
OR you find really fine silver powder mixed with the oil,,,,it's the converter.... Could be the filter if it hasn't been serviced in a million years,,but if the oil is metallic ,,,rip er out!!!!

When was the last time the trans fluid and filter was changed??

thanks for the response. i got it fixed. it was the pressure regulator valve for the tranny... the fluid looked good and no metal in the pan.

soooo much better than a new tranny!! :)
