Transmission Innovations
Our MB Transmissions are light-weight, efficient, and powerful, yet easy to use.
Designers are constantly focused on engineering new solutions to make
manual and automated gear shift (AGS) transmissions more
efficient, easier to use, and more powerful. Here are some of the innovations
we've introduced to improve the driving experience.
Keys to an unbeatable driving experience
Transmission Control Unit (TCU)
The TCU is the brain of our automated transmissions—telling the AGS exactly
when to shift for optimal performance and fuel economy. The TCU evaluates truck
weight, uphill or downhill grades, curves and other road conditions to
determine the precise shift points so you can get the most out of your engine.
Plus, it protects the transmission from accidental damage from poor
shifting—eliminating driveline abuse and extending the life of your
transmission.
Two-Pedal System
Mercedes-Benz's innovative two-pedal system for AGS transmissions is easy to
use and requires no special training—perfect for both veteran and inexperienced
drivers. By eliminating the clutch completely, the two-pedal system opens up
more space and makes the driver more comfortable—reducing fatigue and improving
safety.
Lightweight Aluminum Housing
Both manual and automated MBT transmissions feature a lightweight aluminum
alloy housing with integrated bell housing. This reduction in transmission
weight means increased payloads, while maintaining the highest level of
durability.
Hydraulic Clutch Actuation
With sophisticated hydraulic clutch actuation, you get smoother shifts, as well
as increased clutch and powertrain life—not to mention lower overall
operational costs.
PTO Power and Configuration
SAE 6-bolt PTO ports are standard on all MBT transmissions, offering a wide
range of torque and horsepower levels. Configured conveniently on the right
side, the 5 o'clock location avoids interference with exhaust systems.
Sealed Bearings and Heat-Treated Gears and Shafts
The special sealed bearings and heat-treated gears and shafts on MBT
transmissions increase durability to withstand the rigorous trucking
environment, and keep debris from damaging the transmission.
Gear Faces
Larger gears with helical gear faces guarantee easy shifting and quiet
operation.
Clutch System
MB manual transmissions use a 395 mm x-tend push type clutch with cushion
springs. This self-adjusted clutch system with noise reduction at drive-off
leads to increased safety control and comforts.
