Questions and Answers

What is the primary function of this ATF warmer assembly?
It acts as a thermal bridge between the engine cooling system and the transmission, transferring heat to the ATF during warm-up and removing excess heat during heavy driving.
Which vehicles utilize the 25620-2W500 WARMER A.T.F?
It is a standard fitment for the 2.0L and 2.2L CRDi Diesel engines and specific petrol variants found in the Hyundai Santa Fe (DM/TM) and Kia Sorento (UM).
What are the symptoms of a failing 25620-2W500 warmer?
Symptoms include transmission "shuddering," delayed gear engagement, or the presence of engine coolant in the transmission fluid (often appearing as a milky residue).
Is this component a direct replacement for the original part?

Absolutely. This warmer is manufactured to meet exact OE performance and pressure specifications, featuring high-grade alloy construction for a professional, leak-free fit.

Why should I replace the ATF warmer after a transmission failure?

If a transmission fails internally, debris often clogs the narrow passages of the 25620-2W500 WARMER A.T.F, which can starve the new transmission of cooling and cause it to fail prematurely.
