2001 Acura Mdx Transmission Temperature Sensor

What is ATF temperature sensor?

Thermometrics Transmission Fluid Temperature Sensor (TFT) measures the temperature of transmission fluid. It provides input to the control module to modify shift patterns for smoother shifting in automatic transmissions, and also provides over-temperature protection by locking the torque convertor. via

How many sensors does a transmission have?

Typically, two sensors communicate the transmission data to the vehicle's powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission's input shaft. The second sensor is the output sensor, which monitors the output shaft speed. via

What temperature is too hot for transmission fluid?

#1 Cause of Failure

The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure. via

Where is the transmission fluid pressure sensor?

The pump pressure switch is located on the transmission housing next to the pump. The switch lets the computer know what the pressure is coming from the pump when the engine is running. The servo pressure switch is located on the housing near a band or servo in the transmission. via

Does a transmission have a sensor?

A transmission speed sensor calculates the transmission gear ratio when in use. A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car's powertrain module. The ISS sensor monitors the input shaft's speed. via

How do you remove a transmission sensor? (video)


Why does my transmission shifts hard after its warm?

Transmissions shifts hard when hot because their parts tend to get damaged, worn, and malfunction under high heat levels. Your transmission needs fluid to keep cool and if the fluid leaks then it may create more heat and pressure. via

Can low coolant affect transmission?

But if the engine coolant level is low, the coolant won't immerse the transmission cooler properly. So the cooler won't release the heat necessary for the transmission to cool off. The heat continues to increase in the transmission, causing parts to expand and pressures to build. via

How long does it take for your transmission to cool off?

You may wonder how long to wait for transmission to cool down? it takes transmission around 30 minutes for it to cool down. A proven simple fix is the use of transmission fluid additive on a regular basis. via

What temp does transmission fluid freeze?

For this blog's question, we want to talk about transmission fluid and the dangers of freezing. The danger comes from water coming into your transmission. Water freezes at 32° F or 0° C. When exposed to these temperatures, water in your transmission can freeze and expand, causing cracks in your transmission's body. via

Can a clogged transmission filter cause a transmission to overheat?

It means that the fluid that lubricates and cools the transmission isn't getting where it needs to go. This can cause the transmission to overheat, or it can damage the many moving parts within the transmission. via

What happens if transmission overheats?

What Is Transmission Overheating? Transmission overheating occurs when the engine's cooler cannot maintain the transmission temperature at a low enough degree. The inability to keep the engine cool causes the transmission to become damaged and, if not repaired, fail. via

Can engine overheating cause transmission problems?

An overheated vehicle is a common cause of mechanical breakdown and can be the cause of significant engine and transmission damage, therefore establishing the problem associated with the overheating is important for maintaining a well-running vehicle. via
