What test is performed at the end of a shift in progress after synchronous speed has been detected and assures that the transmission attained the desired range?

• A. Off-going ratio test
• B. Ramp-off rate test
• C. Range verification test
• D. On-coming ratio test

Answer: (D)

This question is about validating the handover of control when a shift changes hands. After the transmission reaches the required synchronous speed, the test performed is to confirm that the incoming operator’s control has correctly engaged the chosen gear range. This on-coming ratio test ensures the transmission has actually attained the desired range and that it will remain in that range as the next leg of the journey begins. It’s all about verifying proper engagement at the moment the shift changes over. For context, the off-going ratio test relates to the outgoing side’s changeover and disengagement, ramp-off rate test checks how quickly the system leaves a range, and range verification test is a broader check of range operation but isn’t specifically about the shift-change moment.
