Transmissions
which of the following was not modified with Eaton automated the mechanical transmission.
Auxiliary case
on Generation 3 models the number of ecu’s were reduced to one by combining the shaft controller and the transmission controller
True
on Generation 3 models the new push button is no longer a functioning ECU and is just an input device to the transmission ECU
True
the DM clutch is considered a 3 pedal system and requires the driver to manually apply and release the clutch
True
all auto shift Transmissions require the use of a self-adjusting clutch (solo clutch) electronic engines with J - 1939 communication and an engine brake
True
all ultrashift transmissions are fully automatic and do not require j-1939 communication to the engine
False
which statement is not true about the Generation 3 push button controller
the shift button controller makes the shift decisions and is programmable
the push button controller for generation 2 and 3 is not interchangeable
True
the range and splitter solenoids are the same and can be interchanged
True
which of the following is an incorrect state of a range valve
all solenoids on
which is not true about the inertia brake
that it is actuated by controlled air False
the start enable relay is used to prevent the engine from cranking when
all of the above
The MEIIR relay is needed on the auto shift transmission in case the clutch fails and the XY shifter cannot pull the transmission into neutral
false
select the harness that Eaton supplies
Transmissions
what component on the XY are used to select the rail
rail position sensor, side and low
which device does the ECU use to detect the transmission is in synchronous?
speed sensor
the transmission ECU receives an input from the ignition circuit as a cue to power up
true
the gear display can be used as a diagnostic tool for determining if the transmission is in gear during power up
true
