Eco Gear Tsg 360 - Mercedes-Benz viano 639 series Introduction Into Service Manual

ECO Gear TSG 360

The outstanding feature of the new six-speed manual
transmission for cargo vans is its very large gear ratio
spread with a low-geared 1st gear and a 6th gear
designed as an overdrive. This design is specific to
cargo vans and is intended to help in typical situations
such as when starting off uphill with a trailer attached
and under tough traction conditions or when driving
long-haul stretches on the highway.
This is the first time that a transmission was specifi-
cally developed for van applications and not simply
adapted from an existing passenger car transmission.
First and foremost there is the direct link from the
cable shift to the transmission via the transverse shift
rod, which permits precise shifting.

This is also the first Mercedes-Benz inline manual
transmission in which the gearshift lever is decoupled
from the gear set. This manifests itself in a defined
gear end stop, which in combination with the opti-
mized dampening of the selector and shift cable signif-
icantly contributes to the excellent haptics and high
level of shifting comfort through the entire gear
change sequence.
Advantages:
• Reduced fuel consumption due to lower engine
speed
• Optimized noise and shift quality
• Less load on clutch
• Improved maneuverability
• Main transmission configured for higher torque
(raised from 330 Nm to 360 Nm)
