Apply throttle to synchronize engine rpm with the
transmission’s speed. The arrows disappear, the
current gear position stops flashing, and engine
rpm increases and becomes steady.
NOTE: If the shift is missed, control engine
speed in the direction indicated by the arrows
on the display to synchronize engine rpm with
the transmission’s speed.

General Information, Top 2 and
Lightning
10-Speed RTL/ RTLO and 13-Speed/18-
Speed RTLO Models
Top 2 and Lightning transmissions have 10 selective
forward ratios and a 2-speed rear section. Half of the
10 speed ratios are shifted with the shift lever and
the other half are shifted by moving the shift button.
They shift automatically between the two top gears.
See Fig. 8.26 for the Top 2 shift knob, and Fig. 8.27
for the Lightning shift knob.
There are three types of shifts used with these trans-
missions. Button-only and combination button/lever
shifts are both full gear changes. The lever-only shift
skips a gear.
•
The button-only shift is a gear split shift that
occurs by moving the shift button.
•
The lever-only shift occurs when the shift lever
is moved without moving the shift button.
•
The combination button/lever shift is a gear
ratio change that occurs when both the shift
button and the shift lever are moved.
The small red service light on the Lightning shift
knob illuminates for a few seconds when the engine
is turned on. This confirms that the transmission
electronics are operating properly.
NOTE: If the service light stays on or flashes, or
does not illuminate when the engine starts, take
the vehicle to an authorized Freightliner or
Eaton service facility as soon as possible.
See Fig. 8.28 for the shift patterns for Lightning and
10-speed Top 2, 13-speed Top 2, and 18-speed Top
2.
Operation, Top 2/Lightning
CAUTION
Keep the transmission in gear at all times while
the vehicle in motion. Coasting in neutral could
lead to transmission damage.
