I thought of ya when I saw ATS has a 5yr-500,000mi warrenty on their trans. I am certain it is sick expensive but downtime has its price also. Have you ever thought of swapping out to a steeper gear in your rear? I am assuming you have 4:10's. Something in the line of 4:88 or 5:13's would take a huge amount of stress off of your trans and driveshafts. Maybe a 10 lug superduty retrofit? With the OD, you should still be able to squeak out speeds close to 75-80mph. I just couldn't get this off of my mind these past few days and thought I would put it out there. Also, I know a private trans rebuilder in Tuckerton, NJ; K&N Transmission repair. Keith from K&N was a certified Ford trans mechanic for 17 years and left the dealership because he knew he could build a better trans than the dealership would let him. He builds hd replacements for Fords, Chevys and Dodges that tow boats for companies like Viking and Ocean Yachts. Aside from ATS, this is the guy I trust for my rebuilds. I know friends who have given up on Jasper warrenties and paid him to fix their transmissions because its done right when he is finished. I paid $2400 for a hd E4OD with new converter and was very pleased with the performance. Feel free to save this thread and pm me if you want to consider this in the future. Taller gears would help any of these slush boxes in my eyes. Good Luck.
