Frequently asked questions

What does the AMR4948 temperature switch do?

The AMR4948 is the transmission oil cooler temperature switch that monitors automatic transmission fluid temperature. It closes at approximately 135°C to signal an over-temperature condition in the cooling circuit.

Where is this switch fitted?

This switch fits into the ZF 4-speed automatic transmission oil cooler line, monitoring ATF temperature as it passes through the cooler circuit. It's part of the transmission's warning system, not the engine cooling system.

What happens if this switch fails?

A failed switch can stop the over-temperature warning from triggering, meaning no alert if the transmission fluid overheats. It can also fail closed and trigger a false warning, so replace it if you see unexplained alerts.
