The average transmission overhaul kit contains all of the sealing components you need to to rebuild a specific application: from o-rings to gaskets and steels to clutches. When you open up your kit, the sheer number of small parts inside can feel a bit overwhelming. Despite the organized packages and instructions inside to help you, it can be tough to know if you're missing a part until the unit is torn apart on your bench, effectively bringing your rebuild job to a stand still.
The biggest threat to your productivity and reputation as a transmission rebuild shop is the risk of comebacks. When your rebuild job is unsuccessful the first time, not only do you usually have an unsatisfied customer on your hands, but this warranty work takes up the space in your shop and the time of your technicians when you could be moving on to new jobs. The good news is that you have plenty of opportunities to avoid these losses in the first place with a little bit of careful planning and quality service.
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?
