00:00Many believe that when the automatic transmission starts to malfunction, it is already completely damaged.
00:03But beware, sometimes the culprit is this component called the TFT sensor.
00:07This sensor measures the temperature of the transmission oil.
00:09If the TFT sensor sends a false reading, the computer gets confused.
00:13You may think the oil is too cold or too hot, even if it isn't.
00:17Then it changes bad speeds and modifies the internal pressure.
00:19A common TFT sensor failure is feeling jolts or jerks when shifting into drive or reverse.
00:23It can also take time to make the changes,
00:25because the computer doesn't know the exact oil temperature.
00:29When the computer detects an out-of-range signal, it can activate emergency mode.
00:33The car loses power, gets stuck in one gear, or no longer responds the same.
00:36This is done to prevent further damage to the transmission.
00:39Several codes related to the TFT sensor also appear.
00:42These codes indicate a circuit fault, low signal, high signal, or out-of-range performance of the temperature sensor.
00:48of the transmission fluid.
00:49But the TFT sensor isn't always bad.
00:50It could also be a loose connector, damaged wires, moisture, burnt transmission oil, or low fluid level.
00:56That's why you should never replace parts without checking them first.
00:58To diagnose the TFT sensor, compare the sensor temperature with the actual temperature.
01:03inspect the wiring and check the oil level.
01:05Ignoring this fault could damage the transmission.
