If you tow heavy, spend time in hot weather, or use your truck for demanding daily work, keeping transmission temperatures under control becomes a lot more important. This Fluidyne High Performance Transmission Fluid Cooler is designed to give your GM 6.6L Duramax significantly more cooling capacity than the factory setup, helping your transmission stay cooler and more consistent under load. With over 4 times the heat exchanging capacity of the stock cooler, it helps reduce heat buildup during towing, hauling, and long drives.

Built specifically for Chevy and GMC 2500HD and 3500HD trucks equipped with the 6.6L Duramax and Allison 1000 transmission, this direct bolt-in replacement installs at the factory mounting locations for a cleaner, easier installation process. The aerospace-grade aluminum bar plate construction, proprietary fin design, and extremely dense fins-per-inch layout maximize cooling performance while maintaining minimal pressure drop. Fully welded internal splitter plates help prevent contamination between hot- and cold-side fluids, improving durability and long-term reliability.

Finished in a durable silver powder coat with a proprietary heat-wicking compound, this dual-pass transmission cooler is built to handle demanding conditions while maintaining reliable performance. Featuring -10 AN female O-ring fittings, it’s a strong upgrade for Duramax owners looking for better cooling performance and added transmission protection.

⭐⭐⭐⭐⭐ Great for teething puppies
Size: Small, Color: Pink
I purchased the Nylabone puppy chew toys for my teething puppy, and they’ve been a big help. The toys are the perfect size for a young puppy and feel durable without being too hard. My puppy enjoys chewing on them, and they’ve helped redirect chewing away from furniture and shoes. I also like that they’re designed specifically for puppies, so they’re gentle enough for growing teeth and gums. The variety in the set keeps my puppy interested, and the toys have held up well with daily use. They’re easy to clean and feel safe to give to a puppy. Overall, these are great chew toys for puppies. They’re effective, well made, and helpful during the teething stage. I would definitely recommend them to new puppy owners.

Great Variety for Teething Puppies, Keeps Him Busy!
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
I got this 9-pack toy set for my 11 lb chihuahua-terrier mix puppy, and it’s been very well received by my little guy. He’s been bored being in quarantine until his vaccines kick in and he's also teething. This toy set has made a huge difference. Great variety - you get a combination of rope toys, plush squeaky toys, and even a treat ball, so he often rotates between them depending on what he wants. The rope toys have been especially good for teething, while the softer toys keep him entertained. One of the plush toys has that crinkly texture inside, which he loves. The treat ball is a nice bonus too. I've put treats and his dog kibble in there throughout the day, and it helps keep him engaged and also mentally tires him out. Everything is sized well for a small puppy and light enough for him to carry around easily. The materials feel decent for the price, especially considering how many toys you get. That said, I do keep an eye on him with the softer ones since he’s still a puppy and likes to chew. Pros: Good mix of rope, plush, and interactive toys Great for teething and keeping him occupied Treat ball adds a mental challenge Good size for small dogs/puppies Nice value for the number of toys Cons: Softer toys may wear down faster with heavier chewing Overall, this has been a really useful set during a phase where he’s both teething and needs a lot of mental stimulation. I’d recommend it for small dogs or puppies, especially if you want a variety instead of buying individual toys.

Perfect Puppy Starter Toy Set
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
This toy pack is such a great value for puppies. My puppy stayed entertained for hours and loved having different textures to chew and play with. The toys feel soft but still durable enough for everyday use. A few of the smaller toys are better for light chewing, but overall it’s a fun variety pack for keeping a puppy happy and active.
