If you own an automatic equipped GM vehicle, you've probably felt the dreaded slip before. One day, everything is fine, with crisp shifts and smooth operation. The next day, it's all over the rev limiter on the 2-3 shift and you're suddenly feeling down in the dumps. Unfortunately, it happens to all of us at one time or another and it's usually right after you spend all of your hard earned cash on a new speed part or power adder. If you've never been inside an automatic transmission before, it can be a terrifying experience. Seriously, it looks like it works on magic, fluid, and money, which is almost accurate if you don't really understand what is going on. Luckily, there are plenty of quality transmission shops that can rebuild your transmission without an issue, taking a 400-hp capable factory unit and turning it into a 650+ horsepower tire fryer. And, whether you're going to have someone go through your slushbox for you or you're going to try to tackle it yourself, it's important to understand the key parts of the transmission and how each one works.

Once you know what they do, you can figure out why it is important to upgrade them (or leave them alone), which can save you money and heartache. For now, follow along as we show you how one of the best in the business - Monster Transmissions - assembles a 650-horsepower capable Mega Monster SS 4L65E, and then decide what you want to do about your particular transmission build. From hard parts to the full Monty, Monster can get you hooked up; it just depends on what you're looking for!
