E 250 3/4 Ton Van V8-5.4L CNG VIN M (1997)
When checking fluid at normal operating temperature, the fluid level should be within the HOT marked area on the fluid level indicator. When the
vehicle has not been driven, and outside temperature is above 10° C (50° F), the fluid level should be within the COLD marked area on the fluid level
indicator.
High or Low Fluid Level
A fluid level that is too high can cause the fluid to become aerated due to the churning action of the rotating parts of the transmission. Aerated fluid will
cause erratic control pressure that can result in harsh/soft shifts or engagements, damage to the clutch materials, improper torque converter operation, and
the aerated fluid may be forced from the case vent assembly. If fluid level is high, excess fluid MUST be removed.
A fluid level that is too low will affect transmission operation, causing slipping, slow engagements, or damage to internal hardware. Low level may
indicate fluid leaks that can cause transmission damage.
