Manufacturer’s specs state that pressure readings in drive should be within 10% of pressure readings in park. Are the drive readings as indicated below, within spec? What are the possible explanations for this? What would be a possible customer complaint?

Park
	1st Gear	2nd Gear

 

 

 

 

 

 

 

Solution:

The first gear is within specs; however, the second gear is not within specs.

A possible explanation would be internal leakage for the second gear components.

Possible customer complaints may vary.
