Perform the following steps while monitoring HPCM1 data:

1. Drive vehicle below 35 mph with stop-and-go city driving.
   1. The engine will stop and start as needed.
   2. Ensure smooth operation free of excessive vibrations.
2. Accelerate safely with 100% accelerator pedal to 55 mph, then drive at or above 55 mph.
   1. Monitor for any excessive variable low clutch slip speed during acceleration.
   2. Ensure variable high clutch engages during 55 mph steady state driving and monitor for slip.
3. Slow vehicle by shifting to LOW or pressing the brake pedal.
   1. Ensure smooth deceleration as variable low clutch re-engages at lower vehicle speeds.
   2. Repeat above drive cycle until the transmission oil is above 60 °C (140 °F).
