The Allison 1000 has no doubt proven itself since its mating in 2001 behind the first Duramax equipped GM trucks. Its longevity, even when pushed with moderately heavy loads and higher horsepower have put it at the forefront of transmissions until recently. However, as miles and horsepower accumulate, these transmissions will find their failure points, and ATS has the cure to ensure your horsepower is getting to the ground efficiently.

By increasing the capability of the torque converter, clutch surface area, and line pressure, the transmission can hold 200% more torque than stock. The result is a setup strong enough to handle aftermarket fueling, turbo(s), and tuning, yet is still smooth enough to tow and daily drive with.

ATS Extreme Allison Packages include proprietary modifications to the drums and pistons. ATS has found these modifications necessary when power goes over 700hp at the tires. In addition, the pump is also modified more extensively for increased line pressure. When coupled with the Co-Pilot (standard on all Extreme Packages), line pressure in excess of 300 PSI is achieved - which is needed to prevent clutch slippage.

The Stage 5 features the addition of the ATS Co-Pilot Transmission Controller. The controller dynamically raises line pressure electronically, for additional clamping force on the clutch packs. This prevents slip under high horsepower / high torque situations, such as drag racing, sled pulling or low-speed trailer towing. Shift firmness can be adjusted with the push of a button, so the driver can adjust shift feel in a matter of seconds. The Co-Pilot is designed for trucks at any power level, but becomes crucial at 600+ hp at the tires.

The Stage 5 also includes the ATS Billet Input Shaft, ATS Billet Output Shaft and ATS Billet Intermediate Shaft. On 2wd models, the ATS Billet P2 Carrier, C2 Hub and P1 Sungear are also incuded. In competition applications (drag racing/sledpulling) the stock output shaft can break when launching. ATS includes a billet 300M output shaft to eliminate this point of weakness.

WARRANTY INFORMATION: As with all ATS Transmission Packages, this transmission is covered by a 5 year / 500,000 mile warranty. In order to be eligible for this warranty, all paperwork must be filled out upon installation of the transmission and returned to ATS, to include verifying line pressure with a mechanical gauge or scan tool.

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.

Color: Ultra, Size: Large
This dog ball is so useful! We have a large property and we use the Chuckit! thrower with the ball. The color and material of the toy is very high-quality and lasts for a long time. We have been using the Chuckit! brand for a long time now and we love their dog products! It is a good price and we buy replacement balls like once or twice every 6 months because they keep getting lost in bushes or trees 😂 After some time the color of the ball gets washed out and since our dogs are aggressive chewers, one of the balls we got broke and split open, but it was still usable! The reason that one broke is because we had it for a HECKA LONG TIME! It has no squeaker so when your dog has the ball it wont make any loud and annoying sounds. It is easy to pick up with the thrower and it seems durable and sturdy enough to last them a few months. I don't recommend as a cat toy because this ball is specifically designed for dogs. But is your cat likes fetch i guess it could work! The ball is soft enough to not be hard as steel, but is sturdy enough to not break immediately.

Great quality and folding it in half is a plus. Fits under a seat in car/truck.
Purchased another, as we need one in each car. This is a great ball thrower, especially as it folds in a half. Makes it easy to store under a car/truck seat. Haven’t had any problem with it, great quality!

Fantastic throwing aid!
Very well made, great quality and doesn't feel cheap at all. It's thick, not flimsy or fragile so you can really swing it to launch a ball. Saves my body that I don't have to bend over to pick up the ball anymore, and saves my shoulder that I don't have to hurl the ball anymore. Another bonus is you don't have to touch a slobbered, soggy ball, or a ball covered in dirt. The foldable design is fantastic because I walk everywhere with my dog and don't want to carry around a long stick that's awkward to hold. This folds down small enough that I can securely put it in the back pocket of my jeans without worrying about it falling out. The thing I love most about it is there's a elastic loop at the end so when you fold it you can latch it securely. This small detail is outstanding because I can also hang it on the strap of my sling bag and with the loop secured it will not slip off the strap. This product is so well made and thought out overall.

Excellent toy for play
My dog would play all day if I threw the ball to him. He loves this even though he's 12. The scooped end allows you to pick up the ball without touching it. After a few runs it's covered in dog slobber. So that's a major plus for me! Also, some health issues affect my walking and bending at times. This helps with the bending. This is a great game to play with your favorite friend!
