No torque converter lock-up or unusual vibration is felt during torque  
converter lock-up operations.                                           
                                                                        
Perform the following procedures to raise temperature of fluid:         
                                                                        
1. Firmly set parking brake.                                            
2. Shift change lever to "D" range with brake pedal pressed.            
3. Perform stall test for 5 seconds, let engine return to idle.         
4. Shift trans to neutral and slightly race engine (3000-3500 rpm) for  
   5 seconds, let engine return to idle.                                
5. Perform steps 3 N 4 twelve (12) times.                               
                                                                        
Road test vehicle under the following conditions:                       
                                                                        
Drive the vehicle at 45 MPH in "D" range at approximately 1/4 throttle. 
During T/C lock-up verify the engine rpm's drop approximately 500 rpm   
and no vibration occurs in vehicle.  If rpm's only drop approximately 50
rpm's and a vibration is felt, condition is most likely caused by a bad 
torque converter and it should be replaced.
