After a rebuild, which approach leads to faster convergence of shifts?

• A. Technician A
• B. Technician B
• C. Both Technician A and Technician B
• D. Neither Technician A nor Technician B

Answer: (B)

The speed at which shifts settle after a rebuild comes from using a disciplined calibration process that ties control signals to real, observed shift behavior. Technician B’s approach uses a data-driven, iterative plan: check current shift points and hydraulic pressures with a diagnostic tool, make small, measured adjustments to valve timing or solenoid outputs, and validate each change with a road test across the full RPM and load range. This method quickly shows whether shifts move toward the desired response, allowing rapid confirmation and containment of any drift. In contrast, making large, unsystematic adjustments without verification tends to overshoot or introduce new issues, slowing convergence. So Technician B’s systematic calibration with verification leads to faster convergence of shifts.
