Time Lag Test: Notes

Perform the mechanical system test preparation. (See MECHANICAL SYSTEM TEST PREPARATION .)
Apply the parking brake firmly, and set the wheel blocks for both the front and rear wheels.
Start the engine.
Measure the time lag from the N position to the D position.
1. Shift the selector lever from the N position to the D position with the brake pedal depressed.
2. Measure the time until the shift shock is felt firmly after shifting.
Measure the time lag from the N position to the R position using the same procedure.
