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.

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.

Can't Copy Carhartt

I just received it but I like it so far. Replaced a 12-year-old Carhartt wallet that didn't have RFID protection. Mink oil turns it into a pleasing chestnut, FYSA

Overall a nice wallet
Color: Carhartt Brown (Trifold)
The card slots are a little tight so removing cards can be a hassle. On the other hand, cards won’t fall out if you invert the wallet. I expect the card slots to loosen up with prolonged use. The wallet is great in all other respects.
