Uh oh, your transmission is running hot, which means that transmission fluid isn’t cooling down like it should, which can cause big problems in your transmission. Or, maybe you just want a more efficient and optimized transmission cooler for your Duramax to keep your transmission running cool.

Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. The 2015-2016 Chevy/GMC 6.6L LML Duramax transmission cooler utilizes a stacked-plate design for maximum durability and powerful cooling. Aside from its durable construction, this transmission cooler is significantly larger than the stock core. The Mishimoto transmission cooler boasts a 67% greater core volume, and 164% greater fin surface area than the stock 2015-2016 LML Duramax transmission cooler.

The included CNC-machined adapters connect directly to the stock transmission cooler lines for leak-free cooling. Direct-fit brackets and tailor-made hoses make installation easy. Like all Mishimoto products, this transmission cooler is backed up by the Lifetime Warranty with Accident Protection for worry-free cooling as long as you own it.

A decent oil pan but would benefit from being larger
This oil pan works decently but would be much better if it were slightly larger. At the size it is it is easy to miss the pan and make a mess. The pan holds enough oil for a bike or lawnmower but not enough for a car or truck. The plugs screw on well and don’t leak from my use. But the pan has inner lips that hold oil and make it hard to clean, would be much better if it were a smooth surface. The pan is made of thick plastic though and is well built overall, it just could be designed better.
