Absolutely love it! Why did I wait
"Only thing I was bummed is I had to stop and buy a vent plug. Everything else was included I wish that the plug was as well. It was a slight inconvenience but worth it."

About ATS Diesel Performance
ATS DIESEL PERFORMANCE
ATS Diesel Performance, based out of Arvada, Colorado, is a diesel performance manufacturing company that designs, engineers, and manufactures upgraded transmission components, valve bodies, patented heavy-duty torque converters, exhaust and intake manifolds, electronics, turbochargers, dual CP3 injection pumps, and more for Cummins, Powerstroke, and Duramax powered diesel trucks. Operating out of a humongous 110,000 square foot facility in the heart of the Rocky Mountains allows ATS to keep operations in-house, as opposed to overseas sourcing, and then grueling test their products at altitude and through grades and descents that would make other companies think twice. From full-time RV users who travel nonstop to high-horsepower competition-based vehicles, ATS has the answers.
ATS DIESEL TRANSMISSIONSClint Cannon and Ranee Elder founded Automotive Transmission Specialists in 1993. At that time, the company specialized in transmission repair for all types of vehicles. In 1997, the company "Performance Torque Converters" was founded, and they started doing torque converter rebuilds in-house. Bringing the capability of building torque converters in-house gave them more flexibility to service their racing customers. As the popularity of diesel trucks grew and more people became aware of the power upgrades available for their diesels, problems with diesel transmissions emerged.
Clint started research and development into a more robust torque converter to address the transmission issues. It was discovered that a clutch pack design was the answer to providing a robust torque converter. The development of the TripleLok Torque Converter and the company's focus on Diesel Performance products resulted in a rename of the company to ATS Diesel Performance.
By having their foot in the door before most, it allowed ATS Diesels transmission upgrades to grow with the demands of diesel trucks, putting them at the forefront of reliability. Fortunately for us, Clint didn't stop with transmissions and began to explore and refine upgraded turbochargers, intake and exhaust manifolds, and anything else to generate additional power with the ever-present mindset of maintaining powertrain reliability.
ATS Diesel products are proudly made in the USA.

"Fits well, looks good, tightened hex bolts to proper torque and have had no leaks with provided gasket. Product did have some rub marks on polished metal - only reason for 4 stars."

Q&A
- Will this fit a 2002 f250 super duty power stroke
- Yes, these will fit your application.
- On my F250 I have a 12 bolt pattern on the rear differential. I called Ford and they confirmed I have a 10.5 , but 402-900-3068 is a 10 bolt pattern according to the photograph. Will this fit my 2016 Ford F250 Super Duty 6.7 Diesel Powerstroke?
- Sorry for the confusion it looks like the pictures accidentally got swapped for the Dana 80 cover next to it. The 4029003068 would be the correct 12 bolt cover for your application. SNA
