All of the clutches except forward have a what type of valve in their apply circuit?

• A. Trimmer
• B. Governor
• C. Modulator
• D. Manual selector

Answer: (A)

The main idea here is how clutch apply circuits are controlled to make engagements smooth. A trimmer valve is used in the apply path to shape the pressure rise as a clutch starts to engage. By trimming or limiting the initial pressure, the clutch engages gradually, reducing shocks and harsh shifts. Because of this shaping role, most clutches in the circuit include a trimmer valve.

The forward clutch, however, is arranged differently and does not use this trimming valve in its apply circuit, so it’s the exception. The other options aren’t the right fit here: a governor is a speed-sensing device, not a valve in every clutch’s apply path; a modulator valve can vary line pressure in some systems but isn’t present in all clutch apply circuits; a manual selector is a gear selection control, not a hydraulic valve.
