About 2010-2012 Ram 6.7L Cummins Built Transmissions

The 6.7L Cummins Rams may be tough, but their transmissions aren't known for their reliability even at stock power levels and during light towing. But when you throw on powerful tuning, turbo upgrades, oversized injectors, and bolt-on parts, the factory 68RFE and AS68RC transmissions can start to let you down or even outright fail. We here at Tier One Transmissions specialize in the manufacture of high-quality 2010-2012 Ram 6.7L Cummins built transmissions that can hold more power than stock, tow heavier loads more reliably, rip around off-road without failing, and tear down the drag strip or sled pull without a catastrophic failure. Tier One's built 68RFE transmissions are available in several different configurations that range from our 2007.5-2018 Ram 68RFE Towing Transmission that's perfect for near-stock trucks all the way to your 2007.5-2018 Ram Competition Transmission whose power limits even we don't know. No matter your Ram's power levels or intended application, we here at Tier One have the perfect built Dodge Ram transmission for your truck or budget.
