re: 4r75e valve body issues? Ford V8 transmissions (needed rebuild)

Also any truck can have valvebody issues, in GM's it's often servos or accumulator springs, Dodge its just the entire vehicle.

I put a performance-tuned valvebody in the 4R70W in my truck years ago, back when Greg Evans had Factory Tech. I also put in a B&M deep sump transmission pan, much easier to do routine fluid changes when you have a drain plug. Like any of them, change the fluid every 30k and have a good auxiliary cooler and it will last a long time.
