Is the Check engine light showing?
If the trans is not fully electronically controlled, ie. It has a trans throttle pressure cable(1996 models most are without TCM), then the OBD II scanner reading is non comprehensive and would not have a linear solenoid.
Only one problem can cause the code, faulty or disconnected lock-up solenoid.
