Frequently asked questions

What is the AMR4948 temperature switch used for?
The AMR4948 is the temperature switch for the automatic transmission oil cooler circuit. It monitors automatic transmission fluid temperature and signals an over-temperature condition, helping protect the transmission from overheating.
Which part numbers are interchangeable with the AMR4948?
The AMR4948 is listed with alternative references 8510043, PRC3139 and PRC8473, all identifying the same automatic transmission oil cooler temperature switch. Any of these numbers points to the correct part.
Where is the AMR4948 temperature switch fitted?
The AMR4948 threads into the automatic transmission oil cooler circuit, typically into the cooler feed or return line. Sitting in the fluid flow, it reads ATF temperature to trigger an over-temperature warning when the transmission runs too hot.
What are the signs the transmission temperature switch has failed?
A failed transmission oil cooler temperature switch typically gives a false over-temperature warning or stays silent during a genuine one. Symptoms usually include an intermittent or constant warning with no real fault. Checking switch continuity confirms whether it has failed.
