I have a 2002 3.3L 4x4 XE and I'm getting a P0744 code. From a dead stop and in the drive gear, I get real high rpms and then a hard shift going into second and again when going into third. @65 mph I'm at about 5500 rpm, 4500 rpm @ 50 to 55, and just high rpm in general. In drive, I get up to 35 mph at about 3000 rpms, but down to idling speed when I let go of the accelerator. I get the best performance when I manually go from first to second and then into drive. And the tranny doesn't catch when I slam on the gas, but shifts hard when I let go. I've scanned it at autozone and got the P0744 code. Their code reads "A/T servo valve solenoid circuit malfunction" the definition says "code P0744 indicates that the torque converter clutch solenoid electrical circuit was intermittent for a predetermined period of time."
I'm thinking about flushing the tranny and replacing the filter and testing the resistance of the torque converter clutch solenoid before I pay for a new solenoid, and maybe even getting a solenoid from a salvaged tranny. What do y'all think? I need opinions

Sounds like you're on the right path...that's where I would start...oh and adding an external tranny cooler token while I was at it

What do you mean by an external tranny cooler token?

He meant that you should add an external transmission cooler when you decide to do the flush. Token must be a typo
