trans am temp gauge oil pressure light switch fluctuating
The outside of the car instrument is the gear symbol, and there is a water temperature gauge in the middle: the transmission temperature warning indicator. Generally on indicates that the transmission temperature is high, prompting you to stop the vehicle to prevent the transmission from burning out.The existing active safety equipment in the general vehicle safety system can ensure the safety and reliability of the vehicle when driving on normal roads and off-road. When the transmission oil temperature reaches 115 ℃, DTC (diagnostic trouble code) will set and store information to help technical analysis.
So what is the meaning of the red oil pressure light on and off? For the oil pressure alarm lamp, it is timely to turn on and off, mainly because the oil pressure has a very important impact on the engine operation, so engineers will not use periodic monitoring to prevent the mechanical failure of the engine caused by the problem of oil pressure within the cycle, and the failure lamp has not been turned on. According to the description of the questioner, the problem that the oil lamp is turned on and then goes out at the time of gear shifting fully conforms to the expression of the red oil pressure alarm lamp, so we infer that the main cause of the fault at this time is related to the oil pressure.
When the transmission oil temperature reaches 135 ℃, the added transmission oil temperature prompt system will display "am135c" (Note: "am" refers to "Qi")"Overheating" message and chime to indicate early warning. The purpose of early warning is to actively remind the user to park in neutral, pull the handbrake and keep the engine in the accelerating state, so as to quickly cool down in the dry cooling mode at the liquid circulation until the alarm signal is no longer displayed.
This action will avoid potential safety hazards due to the continuous rise of oil temperature.If the user fails to take parking action in time after receiving the warning, the transmission oil temperature overheating prompt system will continue to give an alarm. At the same time, the lubrication performance of the transmission oil will weaken with the increase of the oil temperature. When the oil temperature reaches 143 ℃, the transmission oil is likely to lose its lubrication performance, which will lead to the failure of internal components of the transmission due to friction overheating.The time between 135 ℃ at the time of warning and 143 ℃ at the time of transmission oil or loss of lubricating performance will vary greatly according to the actual driving conditions. In the most extreme cases, the interval is the shortest. For example, if the vehicle is deeply immersed in the sand for a long time (20 minutes) and the wheels rotate slowly, the interval from the time of pre delivery to the time when the oil temperature reaches 143 ℃ is about 25 ~ 35 seconds.
