You were very fair with your assessment of expenses. Perhaps at a long term investment in an extended Ford Protect warranty. Just to have peace of mind.

Just curious and may be slightly off topic but still related. I rented a Tahoe with the same trans and after hours of driving. Hills and hwy driving (enough to get it warm) It never once went over 145°.

Maybe apples to oranges? I feel like the Expedition using the same trans would be in a similar operating range.

I traded my Expy Max for a Yukon XL and noticed the same thing. Around town my transmission temp sits in the 145-165 range. Towing I’ve seen it as high as the mid-180s. With my Expy it would be around 210 in town and mid-230s towing in the mountains.

This exact same scenario happened to my daughter with the family onboard. After the tranny overheated and belched out the fluid and smoke from the fluid hitting the exhaust piping they pulled off the interstate(ironically in N. Arizona). After letting it cool down they were able to get back on the road manually shifting. No more over heating and were able to return to place of service. This was 4 months ago. No further issues since.

I service my truck at a Ford performance shop. They do race mustangs, have a in-ground dyno, fiberglass fabrication shop etc. They do rebuilds every day and are very familiar with the VVT issues i.e cam phasers etc with Fords 5.4's and 3.5's.

They suggested I look into a Blazer, Suburban, Yukon etc....basic V8, or the Hemi V8 but not ecobooms.

Just sayin.
