Not sure if this will help or not

F-85 - T/M forward solenoid - Current above 180mA or more continued for 600ms when solenoid is off. OR current value of 3.8A or more continued for 200ms

Check Forward solenoid wiring and connector for issues. Make sure connector pins are seated correctly free of corrosion, make sure battery negative wire is in good condition. Check VCM and connectors for broken wires and corrosion.

Pneumatic truck transmission solenoid resistance check should be 4-7ohms

Cushion truck transmission solenoid resistance check should be 5.4ohms @ 20C degrees

VCM monitors amperage to the transmission solenoids not voltage. Check with low amp clamp.
