To obtain an accurate transmission fluid level reading, the fluid should be within which temperature range?

Explanation:
The main idea is that a transmission fluid level reading is only accurate when the fluid is at its normal operating temperature because the fluid expands as it warms and contracts when it’s cold. The dipstick marks are calibrated for that typical warmed state, so you get a true level only in that range. Within a moderate warm range, the fluid has expanded to its normal volume but isn’t so hot that it would overflow or burn you, so the reading on the dipstick reflects the actual amount in the pan. If the fluid is too cold, the viscosity is high and the volume isn’t at its normal expanded state, leading to an unreliable reading. If it’s too hot, the fluid can over-expand beyond the calibrated marks, also giving an inaccurate result. That’s why checking within that specific warm window yields the correct, stable reading.
