THM 200-R, 400, 700-R4:
When cold, 27 degrees C (80 degrees F), a full THM 200-4R, 400, and 700-R4 transmission will show the fluid level to be below "add" mark on the
fluid level indicator (refer to Figure 1). As the transmission warms to normal operating temperature, the fluid expands raising the level to within the
cross-hatched areas on the fluid level indicator.
