Fortunately for myself I get to drive almost everything Class 2B - 6. Have my own fleet, own a garage that does fleet maintenance, and sub contract as a driver in my spare time. Ive also driven E series 7.3L/6R140 platforms and there is a very noticeable difference when compared to a 7.3L/10R140.

There was a revision in the 6.7 between 2019 and 2020.

2019 was 450/935 and 2020 was 475/1050. IIRC there was a change in piston material along with fuel delivery.

Cab and chassis remained the same power levels with the transmission being the difference. I apologize, I should have been more clear.

What ended up being the problem with your 10r100?

Hi Ron, wondering if you received a response from Mike at the Livonia Transmission plant? tia

Parts interchangability

Since they share the same block, are exhaust systems and other parts interchangeable? Also wondering if 5star or other reputable companies are making SCT tunes for the 6.8. Searching for 6.8 is hard since everything v10 comes up.

Just wondering what the outcome was with the 10r100 transmission failure and if you still have the truck & current milage?

I'm really hoping I just got the one in a million bad one.

I am in the same boat, My 23' STX tranny failed on a camping trip. It now sits 200 miles away at a Ford Repair Shop.
