Take it down to the Lube Center and pay for a transmission flush. Your transmission will drive like new. Seriously, you will be impressed with the improved shifting.
Good call TTZ... the lube boys will replace all the fluid in the transmission including whats in the torque converter that you normally can't drain. 100% replacement of fluid.
What the other guys are recommending a double drain and fill is for the same reason, can't drain the torque converter but try to displace as much old fluid as possible.
The lube boys can do a better job with their equipment.
