When you're comparing transmission overhaul kits, there are so many elements to consider before you make your purchase decision. While all the different specifications can seem overwhelming, it's important to remember that the highest indicator of an overhaul kit's quality is the percentage of OE components inside it. But while you're looking for any brand's OE content, you might notice some different terminology popping up. Some offer OE transmission seals, while others claim that their seal are "OE quality." So what's the difference?
In almost every industry, the final product can only perform as well as the materials inside it. This is especially true when it comes to the automotive aftermarket, with transmission seals in particular. Every manufacturer uses a wide variety of different raw materials to produce its sealing components, and different materials are best suited for different functions and applications. Considering the overwhelming amount of possibilities when it comes to the materials inside transmission seals, some rebuilders fail to really research what they're putting into the vehicles in their shop. Unfortunately, this is a misstep with long-reaching repercussions.
Transmission rebuilds are probably one of the most expensive services you offer. Most rebuild shops charge a few thousand dollars for a full transmission rebuild, and for good reason: not only are the jobs labor-intensive and increasing in difficulty as technology evolves, but replacement parts aren't cheap either. But when you choose the rebuild kit you're going to order, do you know what you're really paying for?
Every part, vehicle, and job that makes its way into your shop for service is different. While it's certainly helpful to have general guidelines for rebuilding vs. replacing transmission parts, the best practice we can recommend is to consider all options (in a timely manner) before selecting the best service solution. So when it comes to dealing with a worn or broken valve body, what should factor into your service decision?
Perhaps the most critical component of your transmission rebuild kit is one of the smallest parts: the overhaul sealing kit. Comprised of all the o-rings, gaskets, and other sealing components you need to complete the unit's rebuild, the overhaul kit is the key to ensuring a successful repair and a satisfied customer. However, it's important for you to know that all overhaul kits are not made equal.
