The general manager told me, when I bought the car (2025 TLX-S), that at the first oil change, I had to replace the transfer case fluid at the same time.

When I read my owner's manual (yeah, read it all!), I recall seeing this also.

But now, can't find it... I read through the maintenance section again, and can't find it.

When I go on Acura Canada website to download the maintenance items for my car, they don't recommend to replace the transfer case fluid at the first oil change.

Anyone has any info on this?

 

In general, early and frequent fluid changes are a good idea. The early mileage break-in period is when the most mechanical wear takes place.
