Its true, the Allison 1000 transmission originally set the bar pretty high upon its initial unveiling on the first Duramax-equipped Chevy back in 2001. Many looked to this transmission as being the cure for any future transmission issues. And to some degree, the Allisons have proven themselves, but as with all things, time, hard work, and horsepower will cause them to fatigue and fail. Fortunately, the professionals at Merchant Automotive know the ins and outs of properly building an Allison to deliver the reliability you need from your truck.

Merchant Automotive has a long history of building transmissions for customers from all over the country who depend on their trucks for many types of applications. The components in the Maximum Transmissions were selected specifically based on our experience working exclusively on the GM Duramax trucks with an Allison transmission.

If you depend on your truck to be there when it counts, the Maximum Work Series Transmission is for you! Designed to optimize the potential of the Allison transmission, even with additional power, this transmission still maintains the smoothness of the stock unit for everyday use, but with increased holding capacity when it counts the most.

Perfect "To Go" Untuck Shirt for all summer events!
Size: XX-Large, Color: White-all White
LOVE LOVE LOVE this shirt! Great quality. The material is soft and just thick enough to not be see-through but cool for our Southern summers or tropical locations. The only thing I would say is depending on your arm to shoulder size, you may want to go up a size. I originally bought an xl for my husband, but it was a little snug at arm hole area, so we exchanged it for a xxl (it is designed so you do not have to tuck it in so the xxl fit and looks great.) I reordered in the blue also. Excellent for weddings, dinner, outings etc.. definitely recommend!

Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

Nice shirt
Size: Medium, Color: Light Green
The shirt is true to size. I'm 5'10" and 160 lbs. and the medium fits well. It is light and airy, and after light pressing holds its shape well. The little cuff on the sleeve is a nice touch. Be aware that the buttons are hidden (if that's the look you're going for). I can't speak to durability as I have only worn it once. I have several Coofandy shirts and they are all nice garments.

Great for the price
Size: Medium, Color: Grey
Nice and light material. Looks good. Suitable for hot temperatures and casual attire. The only thing I've noticed so far that isn't so great, is that the buttons are rather cheap and the middle part broke out on a few of them. Expect to resow some buttons. Otherwise great

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.
