00:00Did you know that the automatic transmission also needs to measure its temperature?
00:03That's what the TFT sensor is for.
00:05This sensor helps the computer know how hot the internal transmission fluid is.
00:09The TFT sensor measures the temperature of the automatic transmission oil.
00:13This oil not only lubricates, it also helps generate hydraulic pressure and keep internal components cool.
00:19When the TFT sensor reports the correct temperature, the computer adjusts the speed changes.
00:24For example, if the oil is cold, it may delay some shifts to protect the transmission.
00:29One of its most important functions is to protect the transmission from overheating.
00:33If the TFT sensor detects a high temperature, the computer can modify the fluid pressure.
00:39The TFT sensor also helps control the torque converter clutch.
00:43The vehicle's computer needs to know the fluid temperature before activating or deactivating this system.
00:48When the TFT sensor fails, the computer receives a false signal.
00:52This can cause sudden changes, emergency mode, loss of power, or the transmission to get stuck in one gear.
00:58speed.
00:58Although the TFT sensor is small, its function is very important.
01:01It helps to maintain the oil and control the shifts in the automatic transmission.
01:04If your car jerks or shows a transmission fault, first check the oil level.
