Transmission Tech Tip: Ford 7.3 Diesel Transmission overheating

7.3 to 6.0 transmission cooler swap

We get calls often on the 7.3 diesel with automatic transmission overheating when pulling steep inclines with trailers. There can be several factors that will cause a transmission to overheat. It should always be diagnosed first. The temp sensor could be faulty, the fluid could be low or need to be changed or there could be internal problems. The 7.3 diesel tends be under powered and can cause extra pressure and heat in the transmission when trying to pull steep hills, but replacing the transmission cooler with the newer 6.0 diesel cooler makes a huge difference. We recently replaced the cooler on a F350 with a 7.3 that was reaching temperatures of 240 degrees when pulling their 40 ft. toy hauler up the grapevine. They called us and were very impressed as they pulled the same hill under the same conditions and only reached 185 degrees. You can add deeper pans with fins and we recommend a synthetic fluid but the cooler will make the biggest difference and is a must on the 7.3 engine.
