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.

Yes Go Nike!
These Nike men's shoes are very comfortable. It's a pretty versatile shoe. I am able to work out in the gym, go for hikes, walk on the street and run errands all with ease and comfortability. They are sturdy, have good cushion and great support for your joints and back keeping you aligned. They lean on the more narrow side for fit so if you have wide feet they may not work for you. The green around the heal is attractive. The price I paid for the shoes was extremely reasonable making them a great value. I have been using them for a couple of months now and they are still in great shape. Excellent buy!

Nice fit, classy looking sweater
Size: Medium, Color: Navy Blue
I bought this for my husband because now that he is retired and lost weight, he needs casual clothing to go out and socialize. This sweater is both classic and sporty, working well in a golf course or a night out. It is soft, washes well and fit perfectly. I am ordering more in different styles and colors. It is light weight and not bulky.

Nice sweater
I wasn't sure what to think of this sweater. It looked nice, but I don't know. Then I wore it out one night. I totally got laid that night. Highly recommend.

GREAT SWEATER...BUT...
Size: X-Large, Color: Khaki
I really like this sweater and am a big fan of this brand. The material is good quality for what you're paying and the material is soft and comfortable and provides good warmth for those chilly mornings or evenings. So why four instead of five stars? Quite simply, the fit. Although it's a classic style and looks good out of the box, I thought the fit could have been better. I ordered the right size and it actually fits my body well enough, but the overall presentation seems a tad off, especially around the chest and upper arm areas. That being said, it's definitely not a deal breaker by any means and I fully intend to get plenty of use from the four colors I purchased. Just don't be terribly surprised if it doesn't hang on the body qauite exactly as you might have intended. Of course, that's a pretty subjective point of view and yours may be totally different.
