Can a thermostat cause transmission problems?

Re: Can a bad thermostat cause a transmission not to… It is absolutely possible for this to be the case. When the thermostat is not reading the temperature of the coolant properly, the engine ECU or computer will sometimes not allow the transmission to shift either correctly or at all.

What temperature does a transmission overheat?

Without enough transmission fluid or effective fluid, your transmission will start acting out. The ideal fluid temperature is under 175 degrees, but as fluid ages it starts to break down and lose its capacity to cool down the transmission. This is when transmission overheating occurs. At 220 degrees, varnish forms.

What are the signs of a bad thermostat?

Here are some of the other problems that can befall your thermostat: 1 Rust 2 Corrosion 3 Deposits 4 Leakage from its mounting 5 Electrical or electronic malfunction (for map-controlled thermostats)

What happens when your thermostat gets stuck in the open position?

A malfunction can result in a trouble code, generated by the engine’s computer, which can turn on your check engine light. If your thermostat gets stuck in the open position, it’ll allow full, unrestricted circulation of the coolant. You might see these issues as a result: These are all byproducts of an engine that is running too cool.

Why does my Trane thermostat not come on?

Check for 24 Vac between B and Rc. Temperature settings do not change. The upper or lower temperature limits were reached. Check temperature setpoints. Check Installer Setup Numbers 0600 and 0610; modify as needed. The keypad is fully locked. Check Installer Setup Number 0670 to change keypad locked options. Heating or cooling does not come on.

What happens when the transmission temperature reaches 290?

The fluid varnish starts destroying the internal components of the engine like the valves. By the time the temperatures reach 250 degrees, the rubber seals have started cracking and leaking pressure and liquid. At over 290 degrees, the transmission will often have stopped working due to damaged parts and seals.
