4 X 2 Gear Selector

NOTE: The vacuum line from the forward sole-
noid will have a red dot on the elbow that con-
nects it to the upper fitting on the valve. The
valve itself should be controlled by two wires: (1)
Orange with white trace wire and (1) yellow with
black trace wire.
5.16. Start the engine, operate the gear selector but-
tons on the dashboard, and observe the vacuum
reading on the gauge. The readings should be
as follows:
• Neutral to Reverse:
Brief rise to roughly 5” HG., followed by return to 0.
• Reverse to Forward:
Rise to 15”-22” HG. (usually 17”-18”) and hold
steady. May pause at roughly 5 HG.
• Forward to Neutral:
Pause at roughly 5” HG., drop to 0.
• Neutral to Forward:
Rise to 15”-22” HG. (usually 17”-18” HG.) and
hold.
• Forward to Reverse:
Pause at roughly 5” HG., drop to 0.
• Reverse to Neutral:
Brief rise to roughly 5” HG. followed by return to 0.
5.17. Identify the vacuum line from the reverse sole-
noid valve. Use a T-fitting to install the vacuum
gauge in-line between the solenoid and the shift
actuator (upper fitting). See Figure 5.17.
NOTE: The vacuum line from the reverse sole-
noid will have a green dot on the elbow that con-
nects it to the upper fitting on the valve. The
valve itself should be controlled by two wires: (1)
orange with white trace wire and (1) orange wire.
5.18. Start the engine, operate the gear selector but-
tons on the dashboard, and observe the vacuum
reading on the gauge. The readings should be
as follows:
• Neutral to Reverse:
Rise to 15”-22” HG. (usually 17”-18”) and
hold steady.
• Reverse to Forward:
Brief rise to roughly 5” HG. followed by return to 0.
• Forward to Neutral:
Brief rise to roughly 5” HG. followed by return to 0.
• Neutral to Forward:
Brief rise to roughly 5” HG., followed by return to 0.
• Forward to Reverse:
Rise to 15”-22” HG. (usually 17”-18”) and
hold steady. May pause at roughly 5” HG.
• Reverse to Neutral:
Brief rise to roughly 5” HG. followed by return to 0.
