Mishimoto 06-10 Chevrolet/GMC 6.6L Duramax (LLY/LBZ/LMM) Transmission Cooler Line KitEvery truck owner knows that it doesn't matter how powerful or reliable your engine is if you can't get any power to the wheels. The transmission mated to your 2006 20010 LLY LBZ LMM Duramax is essential to everything your truck does, and keeping it cool is crucial. Upgrading your transmission cooler with a Mishimoto performance transmission cooler is a good start, but the fluid still needs to get to the cooler. That's where this 2006 20010 LLY LBZ

Every truck owner knows that it doesn't matter how powerful or reliable your engine is if you can't get any power to the wheels. The transmission mated to your 2006-20010 LLY/LBZ/LMM Duramax is essential to everything your truck does, and keeping it cool is crucial. Upgrading your transmission cooler with a Mishimoto performance transmission cooler is a good start, but the fluid still needs to get to the cooler. That's where this 2006-20010 LLY/LBZ/LMM Transmission Line Kit comes in. These high performance lines are constructed with a durable PTFE line that's wrapped in a high-strength nylon braid. The PTFE line is extremely oil and heat resistant for durability in even the harshest environments. To protect the lines against higher line pressures that come with performance transmissions, We've wrapped them in braided high-strength nylon. This wrap prevents expansion and further protects the lines from abrasion. Finally, these lines are capped off with -10AN fittings for a secure and leak-free connection. Like all Mishimoto Duramax products, these transmission lines are backed by our Mishimoto Lifetime Warranty for a lifetime of performance.

My puppy loves it
Color: Teething Stick
It's cute and a good size for my chihuahua puppy. It seems to be slightly tearing at the seam in the middle, but hopefully it will hold up.

Good size for my pug!
Color: Dentachew 3 Pk
I love how it’s a good size for my pug it is easy for her to play around with. I had stuffed animals for her to play around with but it looked so silly to watch her play with something that is 10 times as big as her 😂. I had to buy her these toys and she seemed so happy when she first got them. It was so funny and interesting that she had to chew all three toys and decide which one she liked. At first she decided to play with the rope toy and she liked the rope toy, then she got curious with the rubber toys. She has decided that the rubber toys are her favorite and I’ve tried to engage with playing with her with the rope toy. She gets more interactive with the rubber toys! She also looked so relieved while chewing them so that’s a plus!

Dog loved, started to break down after 10 minutes.
Color: Hedgehog, Color: Hedgehog
I don’t know why it’s so difficult to find a quality teething toy that won’t begin to break down within (in this case) the first 10 minutes. I have a 17lb, 5 mos old Bernedoodle and she’d broken two pieces off the snout in 10 minutes and tried eating them. Yeah, yeah, they’d most likely pass - but this shouldn’t happen with a product specifically sold as a dog chew toy and listed for teething. On the plus side, she loves it - but I can’t obsessively monitor her every second of her teething either. Hit with the dog, frustrating for the ‘parent’.

Get this for your teething pup ASAP!!!
Color: Hedgehog
Immediately calmed my Bichon Frise puppy who is going through a tough teething & nipping phase ... None of the other teething toys were really engaging him, so as a result he would get restless and start biting at air, lol. This worked immediately at keeping him occupied and content. It also freezes great for him to cool his gums after a nap. Get this teether, you will not regreat it!

Good for Teething puppies
Color: Teething Stick
After getting my fingers chewed and bitten by my new foster - 8 week old Yorkie , I was desperate to find good teething toys. Fortunately this one arrived quickly. Turned out to be very good for teething puppies! Charlie loves this cooling stick. Once it’s frozen, the cold really seems to soothe his sore gums. The icy part doesn’t stay frozen for long, but it works so well that I bought a second one to keep ready in the freezer while he’s working on the first. Even after it warmed up, he still enjoyed chewing on the soft stuffed part and the tentacles. The product card says not to use it as a chew toy, so supervision is a must, but it held up just fine so far. Overall, this has been a big help during the teething phase — short-lived when frozen, but very effective while it lasts! And worth every penny to save my fingers from being a chew toy.
