Modern transmissions work hard, so shouldn't their oil seals do the same? Inferior seals are one of the most major diagnoses of transmission fluid leaks that can damage the unit beyond repair. When you're rebuilding transmissions every single day, it can be easy to forget how critical these small parts are, but in a system that operates under such high demands, the value well-made oil seals should never be underestimated. In today's post, we're here to discuss the importance of choosing quality when it comes to transmission oil seals.
When a new transmission application hits the automotive market, it's only a matter of time until rebuilders need a seal kit for it in their shops. While warranty lengths give aftermarket seal manufacturers a few years to develop a kit before then, you might be surprised by the amount of work and analysis it takes to launch a kit to the aftermarket. While every manufacturer will have a slightly different aftermarket transmission seal kit development process, it's a mistake to believe that every process is equal.
While the automotive aftermarket is constantly introducing new parts to service late model vehicles, but not all brands and manufacturers can or will keep up the same pace. The overhaul kit market is a great example. Did you know that some seal providers have their overhaul kits ready before a transmission application even comes out of warranty? While some brands lag behind, others put in the effort and resources necessary to have quality seal kits ready before you're likely to even need them.
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.
Transmission rebuilds are some of the most high-dollar services in the automotive industry. Your shop might be bringing in as much as a few thousand dollars per rebuild, not to mention any smaller, supplementary transmission repairs and maintenance you might also take in. So when that big of a job is at stake, shouldn't it be your top priority to eliminate as many risks as possible? By rebuilding it right the very first time, you can protect the success of your service and save money for your shop at the same time.
