2016 Honda Pilot 

Hi - Now that I'm WFH permanently, I'm a daily watcher of your channel during my lunch break. I've learned so much. Your advice is right on.

Just had the 105K service on my wife's 2016 Honda Pilot. This is what they did for $2,198.70  I was shocked by the price. In your opinion, do you think it was this a fair price?

Replaced timing belt

Replaced tensioner

Nerpentine belt

valve adjustment

Valve cover gaskets

Coolant

inspected water pump (not replaced)

Replaced spark plugs

We've had needed no other repairs on this vehicle except new rear brakes at 90,000. Have done every Honda recommended service. Change oil every 5,000. Honda did some recall/TSB transmission work under warranty at around 70,000 miles. Car runs like it did day one. No complaints. 25.5 MPG consistently. How often should we change the transmission fluid?

Thank you!
