How do you know its slipping, do your rpms increase for the same speed? Your transmission has a lock up torque converter and the computer monitors the slippage when its locked, and if it detects more than 100-200 rpms slippage it will no longer engage the torque converter clutch eliminating lock up. The slippage could be caused by the torque converter clutch(TCC) apply valve wearing the valve body and having pressure leak by instead of being applied to the TCC- it happens to the transmission that gm puts in rear wheel drive vehicles(4L60e) and the trans in that car should be the 4T60E which probably suffers from the same problems
