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.

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.

Excellent customer support, great quality products!
Size: 9.8ft
Very impressed with all of Govee’s products so far. Have a vintage LED strip that has worked flawlessly for over 4 years. Recently outfitted entire outdoor patio enclosure with 2 COB LED strips and 2 pro ceiling lights. All paired very well with Matter and Apple Home. One strip had connectivity issues and Govee quickly responded snd sent a free replacement without any pushback. Very impressed and appreciate the service and quality!

Light weight and large privacy screen
Color: Black, Color: Black
The privacy screen is light weight and of great quality. The screen can block sight and also is easy to set up. It screen is sturdy and stable. It is a cheap solution for separating paces in rooms. The privacy screen is of black color and good good in many places. It can be folded when not used and does not take much space for storage.

Great divider!
Color: Black, Color: Black
This was really easy to set up and really works to decide the room. The material is dark enough that you have your privacy. Good for the price

Over all review
Color: Black
It’s not a bad divider, the instructions are okay but once I figured it out on my own it was easy. The quality is fine I like how it’s made of metal. The only downside is fall for me is the height. I’m 5”4” yet it’s suppose to be 6 feet tall but it seems to be a little shorter than that. If it was taller and the instructions a little more clear it would get 5 stars.
