the 9-speed transmission is "fill for life" and fluid level cannot be checked
remove the level plug and check for fluid at the bottom of the threads
the vehicle must be driven 12 miles before fluid can be properly checked
use the scan tool, special tool, and temperature chart

A. General Topics
During a rock cycle from reverse to 1st gear, clutches C, D, and F dog are all applied. What is the function of these clutches?
The D clutch prevents the F dog clutch from fully matching the turbine speed in neutral.
All three are brake clutches and will stop the planetary components and prevent the vehicle from rolling.
The C and D clutches are partially applied (slipping) to prepare a rotational change. F dog clutch provides speed matching for synchronization
The C and D clutches are partially applied (slipping) to prepare a rotational change.
A. General Topics
What is the name of the electrical component in the figure as shown below?
Transmission range sensor
Transmission pressure sensor
Transmission input speed sensor
Transmission output speed sensor
A. General Topics
What can be damaged if the final drive seal removal tool is inserted too deep?
The B-clutch adjustment shims can become unseated
The (primary) integral oil deflector valve
The final drive bearings
The integral differential O-rings will be torn
B. Activity Based Questions
On Activity 1, at multiple times during the flight recording, the Pressure Control Solenoid current drops very low. What does the purpose of this pressure drop?
The rapid shifting results in the TCM increasing the line pressure to quickly engage the A dog clutch for 1st gear.
Yes; it is likely in the rock cycle because the vehicle speed shows a rapid change in speed.
The pressure is lower during release for both the A and F dog clutches.
It is modulated to assist in the release of the F dog.
B. Activity Based Questions
On Activity 1 during the flight recording between -51.250 seconds, why TCM is applying the E-clutch?
To get the gear set in the right position for the A dog application
To get the gear set in the right position for the F dog application
To get the gear set in the right position for the D clutch application.
To get the gear set in the right position for the E clutch application
