Hi, me dealership recommended a few things for me to do for my 2013 CX-9, 55K miles:
1. AWD service: I was told it refers to front/rear differential and transfer case.
2. transmission flush.

My questions:
1. the user manual only said if the vehicle is driven in harsh condition, change rear differential at 30K miles, but never mention anything about the front differential, do I need to worry about the front differential?
2. the user manual also didnt mention anything about transmission fluid, the dealership asked me to look under "severe service" which I did, and still no words on transmission fluid, what gives?

thank you for your time.

Best,

 

The front differential ( correct name is PTO ) is a ticking timebomb. Changing the oil is a very good idea.

Also if you want the transmission to last changing the oil is a good idea.

 

thank you, grim_reaper, some follow-up questions if you don't mind:
1. what is the specs for the front diff fluid? I downloaded the manual and found it only has specs for the rear diff. oil which is SAE 80W-90 for 1.1 Qt, is it the same for the front diff oil?
2. the same manual talks about "automatic transaxle fluid", is that the same as the transmission fluid?

Best,
