Operating outside this range can lead to problems:
* Too cold: The transmission fluid may not flow as freely, resulting in delayed shifts, rough shifting, and increased wear.
* Too hot: The transmission fluid can break down, leading to slippage, burnt fluid, and potential catastrophic failure of the transmission.
The best practice is to consult your truck's owner's manual for the manufacturer's recommended operating temperature range for your specific vehicle and transmission. The manual might even specify an ideal operating temperature. Monitoring your transmission temperature with a gauge (if equipped) is also a good idea, allowing for proactive maintenance if temperatures become excessively high or low.
