I doubt the mechanic is bored with 1.3 million trucks recalled back to the 2011-13 model years for transmission snafus, and THIS ONE. just issued recently

Because when you own a business that depends on your truck(s) you can't dick around. Every minute those tires are not turning is a minute you're losing money.

Probably worried Ford will loose 3 billion supporting their Lightning product while neglecting their ICE products and uncle joe outlawing appliances.

The third cummins goes bad. Also Paul does mention snap ring failures on the Aisin transmissions.

With that said none of those trucks ever had any issues but I did spend a ton of time and money on maintenance and driving an hour out of my way to make sure that the DPF filters were clear.


Lol, looks like you downsized to a small truck and small camper.
But you sold the diesel because you are paranoid about issues you didn’t have?

They are. The AISIN has been used for many years in many Medium Duty applications in several different brands.

My son's friend was at "Rednecks With Paychecks" a month ago in TX. He took his 3500 RAM/Cummins/AISIN thru many of the mud bogs. Completely smoked his AISIN. Guess they need the cooler that was completely clogged with mud.
