If it is proven that the TCC is slipping, the engine will be revving higher than it needs to and gas mileage will suffer greatly.

And in your mind, that's "up to date" for that many miles? If so; you have no concept of vehicle maintenance. Read the published schedule - it's nearly identical this one, which as you can see, repeats at every 60Kmi. So you SHOULD have done the 120Kmi service - not just an oil change.

BTW
K&N oil filters are overpriced, and NOT better than Ford.
