The factory Ford 4R100 suffers from weak points in the converter, clutch pack assemblies, valve body and line pressure limitations. These weaknesses arise when the motor's power is increased or in towing applications. ATS addressed these concerns by re-designing the torque converter, transmission pump, valve body and clutch packs. The result is a solid transmission setup to meet the demands of your Ford Super Duty. Ensure that the power of your Powerstroke is getting to the ground with an ATS Transmission Package.

By increasing the line pressure, clutch pack surface area and modifying the valve body, the 4R100 becomes a consistent, responsive and dependable transmission. The Stage 4 includes a billet 300M input shaft. As power increases over 400hp, or considerable weight will be towed, the input shaft takes the brunt of it. The ATS input shaft is designed to withstand extreme torque, converter lock-up sooner than stock, and competition and towing use.

The Stage 4 package includes a Co-Pilot Transmission Lock-up Controller. This controller allows the user to lock the converter based on vehicle speed. The result is more power to the ground at a lower speed, thus improving acceleration, lowering transmission temperatures and helping fuel economy. The Co-Pilot will also synchronize torque converter lock-up with an exhaust brake, for added braking force.

The Stage 4 package adds a billet flex plate. The flex plate becomes important in high horsepower/torque applications, during competition use, or when towing heavy loads. By increasing the reliability of the flex plate, we can ensure a solid transfer of power from the motor to the transmission. The ATS Stage 4 4R100 is designed for trucks that see daily driving and heavy towing duties, aggressive tuning, competition use and a modified turbo and/or injectors.

SHIPPING POLICY - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. We do not offer free shipping on transmissions, however, we do offer a very competitive rate charged at checkout checkout. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we can supply you with a quote on the return shipping as that is not covered in the original shipping cost. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

Cotton Fluff Around a Mostly Empty Bag
Size: King (Pack of 1), Style: High Loft (6"-7")
Bought the high-loft king, thinking it would be a great (tall) side-sleeper. What I got? A very nice, completely compressible cotton outer shell wrapped around a bag a bit smaller than a standard pillow. In that bag? A tiny amount of small latex chunks, just about a third full. That’s right, some cotton fluff around a basically empty bag. Could you buy some latex yourself and add it? No, the bag is sewn shut. You could probably fill a small pillow with latex you bought elsewhere and put that in. But seriously, what did you pay Saatva for in that case? Probably as close as I’ve seen a major/high-reputation company get towards a literal example of rip off.

Wrong item ships/decent pillow/price unjustified
Size: Standard/Queen (Pack of 1), Style: Standard Loft (4" - 5")
Sent me the wrong pillow twice in a row. It said high loft and standard loft on the packing, not sure what the problem is. I ordered standard loft both times, and both times they sent high loft. That name is very deceiving though. If what I have is high loft, the standard loft wouldn’t be much thicker than your standard flat down pillow. If you’d like any sort of neck support I’d suggest starting with the high loft and going down instead of the other way around. I am 5’ 7” 130lbs and this pillow does not lift my neck up further than neutral, which is a good thing. Shredded memory foam pillows are significantly higher or thicker if that helps. Pillow itself grew on me. You can definitely feel that there is a different material in the center of the pillow. I ordered it as a gift and ended up keeping both pillows. The price tag on this item is absolutely outrageous. I would have never ordered it for myself. Saatva products don’t last in my experience, we got their firmest mattress and within 2 years it was sagging horribly. I am interested to see how long this pillow lasts!

Side sleeper- lost loft within 2 weeks
Size: Standard/Queen (Pack of 1), Style: High Loft (6"-7")
Side sleeper and within 2 weeks this pillow has lost its loft and has become lumpy. I have spent so much money trying to support my neck and shoulders, this unfortunately is not it. I will continue my search and return this one.

Mixed Feelings on the Saatva Pillow - A Comprehensive Review
Size: King (Pack of 1), Style: High Loft (6"-7")
Updated Edit (June 2024) : In my quest to find the perfect pillow, I initially purchased the high loft version of this pillow, but it turned out to be a bit too high for my liking. I then decided to try the standard size, and I like it much better! The pillow can still get lumpy and requires fluffing, but opting for the standard lower loft has definitely improved my experience with it. While I still use this pillow occasionally, I generally stick with my Purple Harmony pillow more. Changing my rating to 4 stars. --- Background: Over the past 2 years, I have embarked on a journey to find the perfect pillow, testing over ten different options, including numerous high-end brands. My latest trial was the Saatva pillow, renowned for its rave reviews. Expectations vs. Reality: Despite its widespread acclaim, my experience with the Saatva pillow did not meet my expectations. I opted for the higher loft variant, aligning with my general preference, yet I found it too high of a lot even as a primary side sleeper. Material and Comfort: The Saatva pillow, composed of both latex and down alternative, presented a lumpy texture. This inconsistency resulted in varied support depending on the position of my head. Unlike my regular down alternative pillow, the Saatva required frequent re-fluffing and adjusting throughout the night. Comparison and Value: Considering its price and the overwhelming number of positive reviews, my disappointment was notable. Surprisingly, a more affordable down alternative pillow from Amazon outperformed the Saatva in terms of support and comfort, despite the latter's use of higher quality fabrics and its significantly higher cost. Final Verdict: This pillow was one of the last in my quest to discover the "best" pillow. Sadly, it ranks in the lower ranks among the high-end, expensive pillows I've tried. I preferred the Purple Harmony pillow over the Saatva, albeit with reservations about the Purple Harmony as well. Conclusion: The Saatva pillow, while undoubtedly high-quality and possessing comfortable aspects, did not live up to my expectations, landing it in my pile of unused pillows. It may suit others, but for me, I only give it a 3 out of 5 stars rating.

Wonderful!
Size: Standard/Queen (Pack of 1), Style: High Loft (6"-7")
I ordered the loftier version of the pillow and I love it! I'm a side sleeper and I've been having pillow issues over the last few years where I swear every pillow is either too tall, too thin, too soft to provide support, to firm and hurts my ears, or the stuffing is too slick or something and migrates away from wherever I put my head. It's been... A time. But this pillow has been wonderful! I've been using it for a couple weeks now and it's the perfect height for me! The latex inner chamber provides some much needed support, but the softer outer chamber gives me enough cushion to keep my ears from aching. I will say that, while this is the perfect height for me, personally, I think that if you're someone who prefers a pretty lofty pillow, that this might not be tall enough for you. I ordered the taller version, and it feels right for me, but I've noticed in my pillow buying extravaganza that even pillows that everyone else loves that are designed for side sleepers are usually just too tall for me. So if this pillow is right for me, and you prefer a pretty lofty pillow, I really bet that this won't be tall enough in that case. It's definitely more of a medium loft, rather than a very high loft
