ATS 42RLE Transmission Packages, 2003-2006 4.0L Jeep. On the Trail or Street, the ATS 42RLE is backed by a 5 Year / 500,000 Mile Warranty. The ATS 42RLE is engineered to hold the power and abuse Jeep owners can throw at it. Substantial increases in clutch pack surface area, line pressure and shift quality provide the reliability Jeep owner's demand.

42RLE Transmission:
The 42RLE transmission that is used in the 2003 to 2012 Jeep was never designed to handle the abuse of aftermarket add-ons such as oversized tires, extreme off-roading, increased power levels, higher gear ratios or towing. The small 42RLE factory transmission also has a very low volume cooling system, the low cooler flow does not allow adequate transmission fluid circulation through the torque converter to properly cool the torque converter during normal driving much less stressful situations such as four wheeling or hauling any additional weight over stock.

The primary hydraulic pump of the transmission is not big enough to support the increased pressures and lubrication that is needed to keep the clutch packs and gearsets alive at higher power levels.
Other design limitations of the 42RLE plague the ability of the transmission to handle much power over stock. The stock torque converter is manufactured using stamped steel parts that make up the lock-up porting of the converter. The converter cover will deflect under power causing the converter clutch to slip under load creating excessive heat and clutch material to shed from the lock-up piston.

The combination of heat and debris from the converter clutch causes transmission failure as the material from the torque converter is flushed into the transmission.

The ATS modified 42RLE has been redesigned to correct all these problems and handle increased power levels of larger displacement engines, supercharged or turbocharged engines, larger tires, or heavy towing. We understand the real-world abuse that this transmission is asked to do in modified applications, so we came up with the fixes for it.

ATS has developed a combined technology utilizing recalibration of the hydraulic circuits inside the transmission, including revamped accumulator rates, reprogramed clutch to clutch apply and release timings, and line pressure rise rate to perfectly match the torque output of the engine. These enhancements, along with other key hydraulic modifications which ATS makes, must be done to ensure the clutch packs have the correct apply and release rates when commanded on or off. As well, the transmission hard parts have many limiting weaknesses which do not allow for increased power levels over stock. Specifically, the light duty shafts and hubs must be addressed.

All these areas are addressed in our transmission to allow for increased power levels and reliability. Here are some of the modifications we do to the 42RLE transmission so it will handle the extreme use that you're looking for.

TruLok Torque Converter:
• Billet torque converter cover
• Heavy Duty Carbon Composite Lock-Up Clutch
• Harden Pump Hub
• Harden Turbine splines
• Stall Speed is better matched to Engine torque curve
• Torrington bearings construction for better thrust load

Inside the Transmission:

Pump Assembly:
The pump body is redesigned to utilize an oversized pump gearset, this provides for increased cooling and lubrication to the torque converter and transmission gearset. This redesign also eliminates the common pump problems that causes premature transmission failure due to excessive heat. The main pressure regulator circuit is modified to enable a broader range of pressure that can be commanded from the TCM. This allows the pump to lower line pressure when the engine is at low loads and more responsively raise pressure above stock to react with increased engine torque and horsepower levels.
Rotating Clutch Drum Assembly and Clutch Packs:

Clutch modifications are generally one of the most impactive and important items that can be upgraded in any transmission. In the case of the 42RLE transmission, there is little room for additional clutches so modifications must be done to pressure plates providing increased clutch surfaces. All clutch packs are replaced with High performance clutch plates and steel separator plates providing the best friction surfaces available. The problematic Over Drive clutch pack has an increased clutch count maximizing its ability to hold torque.

Valve body:
The valve body is considered the nervous system of the transmission; the valve body is responsible for converting the electrical signals from the TCM into hydraulic actions. The 42RLE uses a non-synchronous, clutch-to-clutch design. This means that the shifts from gear to gear must be timed perfectly thereby releasing and applying a friction clutch to achieve a flawless shift.

Because of the sensitivity of the hydraulic circuits, we heavily modify many areas of the valve body. Hydraulic oil flow is ported to certain clutch packs where additional pressure is needed. The accumulator piston seals have been redesigned to ensure hydraulic pressure integrity.

The accumulator plate is made of high-grade material to compensate for the additional pressure that the accumulator pistons and springs exert during heavy power situations. Also, the ATS 42RLE valve body can be purchased separately and installed in a stock transmission for increased transmission capacity.

Planetary Gearset:
The main planetary gearset is reinforced to prevent the pinion deflection that causes gearset failure.

Case and Pan:
The main transmission case does not require a lot of conditioning aside from a few small hydraulic modifications to allow for proper oil flow. At higher power levels, the transmission case does need to be strengthened. This is a simple fix that is taken care of with the optional heavy-duty cast aluminum transmission pan, which was designed in part to act as a girdle, thus eliminating the flex in the case.
The heavy-duty aluminum pan will clear aftermarket skid plates and the cooling fins allow the transmission to run cooler and it has an oversized drain plug on the side so it can be accessed for easy service.

ATS Auxiliary Transmission Cooler: (Included in Stage 2)
The ATS 42RLE Auxiliary Transmission Cooler Kit is designed to work with your factory-installed transmission cooler. The lower the temperature of the oil in your transmission, the better. With added cooling to combat the heat, you can minimize the risk of the most common transmission failure: overheating.

Features:

  • Auxiliary cooling that enhances factory transmission cooler
  • Extends transmission lifetime
  • Lightweight cooler, heavyweight performance
  • ATS limited warranty
  • Fits all 2003-2006 4.0L Jeep Wrangler JK with automatic transmissions

Application:
2003-2006 Jeep 4.0L

Coop Home Goods Eden Bed Pillow Queen Size
Team Name: Eden, Size: Queen, Color: Classic
I am very satisfied with the Coop Eden Bed Pillow. It is clearly a high-quality product that is well worth the investment. Here are a few reasons why I highly recommend it: Fast Shipping & Great Packaging: The pillow arrived very quickly. It was packed beautifully in a box that was both aesthetic and very functional. Initial Scent , There was a slight 'new pillow' scent upon opening, which is totally normal. I let it air out for a few hours and it was completely gone. Fully Customizable Comfort: The pillow itself is incredibly comfortable and looks great. The best part is the ability to add or remove fill to reach your exact preferred loft. It even comes with an extra bag of fill, so you can make it firmer or softer depending on your needs. Being able to determine the exact volume is a game-changer. Easy Maintenance: It comes with a lovely outer cover that is removable and washable, which is a fantastic and practical feature. Overall, you can really feel the quality of this pillow. If you are looking for a customizable, premium sleeping experience, this is definitely the one to get!

Amazing pillow - adjustable filling
Team Name: Eden, Size: King, Color: Crescent
This pillow is AMAZING. My wife loves it. The crescent shape is cool and unique and enables your neck, back, and shoulders to lay better on the bed. My wife is a back sleeper and sometimes side sleeper. What’s amazing about this is you can adjust the quantity of the filling to your preference. It came with an extra bag if you want to fill it with more. We ended up taking a fair bit out. The card it comes with was super helpful illustrating how your head should rest on it, which showed my wife she had to take some out for her neck to be flatter. It seemed too firm at first so taking out the filling helped. The material inside is super fluffy, light, and airy- it’s extremely soft! As soft as down or other material. I mean this is an amazing pillow. It is luscious and super comfy. It is expensive but worth it.

I can't sleep without this pillow.
Team Name: Eden, Size: King, Color: Classic
This review is for the King size, adjustable Eden pillow. I bought the original years ago and somehow lost it when I moved recently, so I bought the Eden to replace it. Years ago, these pillows were not adjustable but I loved it anyway and was truly upset when I discovered it was missing. I actually lost sleep over it. When I found out they're adjustable now, I about lost my mind over the possibilities. In fact, I love the adjustable, Eden version so much that I bought another one. So yeah, I have purchased this pillow 3 times and have not been happier with any other pillow. Bad news first. The odor. You should know that they claim the foam is packed "fresh." This means there WILL be an odor when you receive it because it hasn't had the opportunity to air out. You'll have to do that yourself. Maybe they'll find a way in the future to "pre-air" the foam they use. For now, just accept that it's WORTH THE WAIT and really not a big deal. Don't return your pillow just because of the odor. It WILL go away and you don't want to miss out on this fantastic pillow. They suggest letting it sit for 24 hours or throw it in the dryer. Neither of these methods are long enough, in my opinion, but please be patient. I have experience with 3 of these pillows now and tried different techniques. This is what works best for me: Upon arrival, I immediately remove the outer pillowcase and set aside. Over the course of 48 hours, I let it sit on the bed in my guest room with the ceiling fan on and I "fluff" it 3 or 4 times each day. (I will describe proper fluffing technique for shredded foam later) Then I throw it in the dryer on low for a full cycle. Then put the case back on and it's done! You'll never have to worry about that again and soon you won't even remember having to do it. Now that THAT'S out of the way... I love that these pillows are adjustable now. They really packed in the foam on the king size! I'm not kidding. There was so much foam in my pillows that they, frankly, were too heavy and way too firm for me. I've seen some negative reviews to the contrary. Maybe since then, they've increased the amount of foam they include (they should keep that up, if that's what happened). That's not how I like my pillows but some folks might be into that so I'm glad they put enough in there for those who need a lot of support. They do include 1/2 pound of extra foam in case you want a true, solid-as-a-rock feel. I do not. I'm a stomach and side sleeper, who likes more "squish" to my pillows, so I ended up removing so much foam from my 2 king size pillows that I have enough to make 2 standard sizes with the same squish factor. Not kidding. I went to the Coop website and purchased 2 standard liners and cases that I'm going to stuff with the excess foam and use on my guest bed. I anticipate some of my guests asking where I got the awesome pillows. :) As we all know, memory foam holds heat too well and some foams will kick you right out of bed because you just can't stand to be that hot anymore. I did experience heat retention in the "original" that I had for years. I flipped the pillow over to get the cool side. I assumed all memory foam was like that so I put up with it. I don't get that at all with the Eden version. I'm a hot sleeper but I haven't had any issue with the Eden at all. The Eden has the blue foam in it that's gel-infused. I don't use anything extra or fancy to keep them cool. The foam is in the provided liners and pillowcases and I cover those with normal, cotton pillowcases. I did see a couple reviews that claim their pillows went flat after a while. I'm confused by this. I had my first pillow for years and never experienced any change in texture. As with ANY shredded memory foam pillow, they need to be "fluffed" every now and then. In fact I fluff all of my pillows occasionally, regardless of the stuffing used (I have a variety of textures on my bed). But regardless, shredded memory foam pillows don't go flat. It's just not a thing. If you feel like it's flat, fluff it. Get rough with it. The shapes of the shreds can, over time, start to fit together like puzzle pieces and can become compact in some areas in the pillow. Maybe this is what creates the illusion that it's flat? "Fluffing" a shredded foam pillow involves breaking all the pieces up so they can move independently again. To achieve this, you have to grab several areas of the pillow with both hands so you have clumps of foam in your hands and then sort of jostle everything around in there, breaking up all the chunks. I usually grab and use the same motion I would use to bang cymbals together and then repeat all over the pillow until it feels like everything is separated again. I find this technique to be most effective when I grab around the edges. This takes only 5-8 seconds to accomplish and is completely normal maintenance for a shredded foam pillow. Final thought: Shredded memory foam pillows are not for everyone because comfort is subjective. We all sleep differently and have different needs. After reading through some of the negative reviews, I've determined that some of them HAD to have been left by people who have never used a shredded foam pillow before and have determined it's not for them. COOP has a generous 100 night, no questions asked refund policy, so it doesn't hurt to try it. I don't view those reviews as a poor reflection of this company's products, but rather that the consumer tried something once and decided shredded foam pillows are not for them. I do have some experience with shredded foam pillows and can tell you that the Eden is, hands down, the best and highest quality that I've found on the market.

Great Pillow and Highly Adjustable
Team Name: Eden, Size: King, Color: Classic
I have used a Claritin Down Alternative Pillow in the past, but they are no longer available. I am very picky with my pillows and have had a difficult time finding one that fits my needs. I decided to purchase the Coop Pillow despite the high cost. After several weeks of use, I am glad I found this one. The pillow has just the right amount fluff and support. I like that it comes with extra fill that I can use to adjust the its firmness, but I didn't need it. I'm a side sleeper and it was great right out of the box. The outer shell of the pillow is soft and very good quality. I am so glad that I found an alternative to my Claritin Pillow. The reason I only gave it 4 stars are for two simple reasons. First, the cost. This product is very comfortable, but there is no magic to its construction. The fill appears to be just finely shredded memory foam. The extra fill doesn't even come in a storage bag. It is wrapped in plastic. If you open it, you will need to find a separate storage container to put the excess fill. For this price, I would expect more. Second, this pillow is advertised as being "cool" to sleep on. However, I find it warmer than other pillows to the point it seems to trap heat. My wife has the standard Coop Pillow and I feel that it is "cooler" than this version. Of course, this is very subjective and you will need to test for yourself. Overall, this is a great pillow that has endless adjustability due to the extra fill provided. A pillow for everyone!
