Bought this 2019 F 150 XLT used in 2023. has 104,000 miles now.
Had the Cam Phasers done in 2024.
Tranny Fluid and Filter changed in 2024.

Those of you still running 2019 F150's ,how long are you planning on keeping them?

 

It's my firm belief the 3.5 with new style phasers and properly maintained will last into the 200k range. The 10.speed may need some work by then. I may be having a cdf drum issue on mine.

 

What is a cdf issue ?

 

CDF, is an internal issue with 10 speed automatic transmissions. It’s actually the drum that holds those gears.

There are 3.5 EcoBoosts out there now with well over 300-400k miles. Do 100k mile services every 50k, and change the oil with full synthetic every 5k miles, and you will likely have a happy engine that lives a long life.
