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 6 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 6 also includes the ATS Billet Input Shaft, ATS Billet Output Shaft and ATS Billet Intermediate Shaft. 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.

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.

Decent
Size: 10FT, Color: White
Would of gave a 5 star rating but in terms of quality it’s decent as far as advertisement of it being 10ft is a lie I still had one of my original apple 10ft cable and these are technically 8-8.5ft. So far both boxes and cables still functional and working 5 months later better than most chargers you will buy at a gas station, that will only last about 2-3 months.

I highly recommend this charger because they are durable and provide a quick, long lasting charge.

Perfect charger
Size: 10FT, Color: White
Very impressed with how quickly the charger works. The longer cable has made it easier to use the phone while charging and sitting on the couch. No issues with the cable getting tangled or fraying like I have had with others, or pinching and breaking the connection.
