As a transmission rebuilder, it's not enough to merely get your hands on the correct overhaul kit for the unit you're working on. Even the 'right' overhaul kit from some brands don't actually contain all of the parts you need to finish the rebuild job. As we've said before, not all overhaul kits are made equal in terms of quality. The same goes for completeness: not all overhaul kit manufacturers take the care to include every single component you need for a complete rebuild.
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?
