1.
Start vehicle and let idle in Park* for 3 minutes.
*
THM 440-T4: Start vehicle and cycle gear range selector through 1, 2, D, OD, and R for approximately 3 seconds in each range.

Figure 1
THM 200-4R, 700-R4:
When cold, 27 Degrees C (80 Degrees F), a full THM 200-4R, and 700-R4 transmission will show the fluid level to be below the "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 area on the fluid level indicator.
