RB - thanks for the help, the TPS is the next thing i'll check. I wasn't aware the TPS actually effect the torq converter. Looking up on Alldata, it looks like there are two TPSs, one for the ECU and one for the tranny. I'll let you know what i find.

Thanks,
-Rob

EDIT: I'm definitely starting to think you're onto something here. A little more research on Alldata revieled:

The most common failure on this sensor is a spike of voltage at approximately 1/4-1/3 throttle. If this condition exists, the TP must be replaced. The most common complaints for this sensor are in and out of lock-up and erratic shift timing.
