The 2002 and 2003 manuals say the same thing. Do not drive the truck if the fluid level is too high.
Cycle the shift lever through all positions with the engine idling. Then check the trans fluid level with the engine idling in park.
Fluid level in the crosshatched area is correct for a trans at normal operating temperature (150~170F). If the trans fluid is at shop temperature (50~95F), the correct level is between the two holes.
