Transmission Oil Cooler
The transmission oil cooler keeps your transmission fluid at a safe temperature, which is key to preventing overheating and wear. When it gets clogged, corroded, or leaks, your transmission can run too hot and suffer damage. We test, clean, repair, or replace the cooler so your transmission stays cool and lasts longer.

Frequently asked questions
What are the signs of a bad transmission oil cooler?
You may notice the transmission running hot, fluid leaks, a burning smell, or rough shifting. In some designs, a failed cooler can mix transmission fluid with engine coolant, giving a milky look to either fluid.
Do I need a transmission cooler if I tow or haul heavy loads?
It's highly recommended. Towing and heavy loads make the transmission work harder and run hotter, and an extra or upgraded cooler helps prevent overheating and extends the life of your transmission.
