Used Freightliner Transmission Models

Used Freightliner Transmission

Freightliner trucks are manufactured by a U.S. carmaker of the same name. Established in 1929, it was the trucks division of Consolidated Freightways. It started operating as a stand-alone establishment in 1942. Also, Daimler AG owned the company for four decades since 1981. They produce both medium-duty and heavy-duty trucks. Also, they manufacture bare as well as cutaway chassis for a range of vehicles. Moreover, they first mainstreamed the use of COE semitractors. Headquartered in Portland, Oregon, this company has been serving the U.S. automobile industry for a long. But, the trucks are manufactured in Cleveland, Mount Holly, North Carolina, and even in a couple of Mexican plants. This brand has been made popular by the Freightliner Cascadia, introduced in 2008. Let's look into the evolution of chassis, engines, and transmissions of Freightliner trucks. Ultimately, we will analyze why the used Freightliner transmission is still a top sell today.

Detroit DT12 Transmission

Detroit D12 or the DT12 automated transmission feature in a range of Freightliner trucks. It blends in so well with the Detroit engines and axles. In addition, the enhanced features allow for easy operations and optimal performance. Built on the DT12, the enhanced features ensure driver comfort. It allows for a terrific powertrain that powers heavy-duty vehicles. It allows for improved fuel efficiency and good low-speed maneuverability. Also, the higher overall ratio makes way for lower axle rations and enhanced downpeeding. The transmissions offer a variety of uses including linehaul, long haul, transfer refusal, and P and D.

Additional DT12 Features

These enhanced features need some explanation for auto noobs. Firstly, the optimized gearing offers faster axle ratios, enhanced GCM, improved torque, and increased durability. Also, they offer improved low-speed maneuverability. These are primarily larger and more robust gears developed to avoid compromising on weight of DT12. Secondly, DT12 offers you new side PTO capabilities, which first translates to SAE 8-bold side PTO opening, commonly dubbed as the 7'o clock opening. It results in increased flexibility and application coverage with other products. Thirdly, you have the new oil pump, now placed within the front bell housing. Driven by the input shaft, allowing for more continuous oil flow. Also, it results in improved efficiency and lubrication at all operating speeds.

Adaptive thermal management belongs in the list of DT12 enhanced features. The oil cooler's adaptive bypass valve balances oil at temperatures ideal for any running application. Additionally, it allows for cooling oul when required and bypasses it altogether when it's not. Fourthly, DT12 also comes with an oil sump, which serves as a bottom-mounted oil intake. It facilitates oil to be picked up by the lower level and therein recirculates by spraying into the gear mesh. Also, it results in less parasitic loss owing to oil splash, thereby bettering overall efficiency. Finally, you have the optimized range group, which is a new and updated planetary gear set design. The overall design minimizes the planetary carrier stress, while also improving the reliability and durability of transmission.

DT12 for beginners

DT12 comes with both the vocational and highway versions. The emphasis is on providing more choice and maximum efficiency. It's aimed at providing cutting-edge performance, better fuel economy, and ease of operations. Moreover, it provides optimal comfort to the driver, which has been the mantra of Freightliner trucks. There are three variants in terms of specifications -DT12-HE, DT12-H, and DT12-HL. The torque provided by DT12-HE, DT12-H, and DT12-HL is 2250 lb-ft, 2050 lb-ft, and 1650 lb-ft respectively. Similarly, the GCW limits of DT12-HE, DT12-H, and DT12-HL are 160,000 lbs, 140,000 lbs and 80,000 lbs. All of the transmissions include 12-speed forward and 4 reverse gears.

The DT12-HL transmission is compatible with the DD13 engine, while the DT12-HE is compatible with the DD13 and DD15 engines. Also, the DT12-HE transmission is compatible with DD13, DD15 and DD16 engines. Commonly, these transmissions are compatible with the Freightliner Cascadia and other Freightliner models. These are transmissions built to optimize weight savings for weight-sensitive applications. Besides, these transmission uses automated manual transmission, rather than automated or manual transmission. It offers the best of both worlds, including manual and automatic transmission. It employs an improvised clutch rather than the torque converter.

However, the clutch and shifting are computed and controlled by the air system. Hence, even a beginner at driving can kick on with the least effort. Also, it uses the least possible fuel to maximize productivity. Importantly the DT12 transmission features 12 speeds for improved output while providing maximum flexibility. The 2-pedal design lets the driver allot their entire attention to what's on the road rather than what's going underfoot. Thus it offers optimal safety and maximizes productivity.
