What is rebuilding a Transmission? Why not replace it?
Let’s start with a more simple question: what is a transmission? But let’s make this short because, honestly, you probably don’t care about the technical details. You care about the role the transmission plays in your car. In short, the transmission manipulates the engine output, to make sure that power is always available to you. The transmission is also responsible for taking the power created by the engine and routing it to the wheels. Pretty important, yeah?
There are four primary types of transmissions. Automatics, manuals, continuously variable transmissions (CTVs), and dual-clutch transmissions (DCTs). In general, CTVs and DCTs are not rebuilt, just replaced.
So, rebuilding. Not a word you hear a lot with cars, right? But in the case of the transmission, it comes into play.
Here’s what happens: the transmission gets taken apart, just like you do with an appliance when it’s not working right. But unlike you and the appliance, the transmission actually gets fixed and put back together in the right order.
During a rebuild, the “soft” parts of the automatic transmission are replaced. These are the elements that easily wear with use and friction, like bands, seals, clutch plates, and gaskets. The transmission cooler will be flushed out and replaced, and the filter will be replaced as well. Further damage will be checked for, and replaced as necessary.
And then it’s all put back together, by people who actually know what they’re doing.
So, why not just replace the transmission? Simple. Sometimes, it’s cheaper to rebuild it. Would you rather spend more money or less money? Thought so.
Symptoms of a failing Transmission
You take your transmission for granted. It’s natural. Everyone does. You don’t realize how nice it is to have a fully functioning transmission until you don’t have one. If your car has hard shifting, gear slipping, is banging into gears, or has blips of accelerated RPMs without increased speeds, then your transmission isn’t feeling so hot.
If you drive a stickshift, and you hear grinding when you shift gears, you’re either a bad driver, or there’s something wrong with your transmission. You can decide which is worse.
If you drive an automatic (don’t worry, only some people are judging you), then you might hear a wildly annoying whining noise from a grumpy transmission.
Check engine light
Your secret isn’t really a secret. We know that you like to ignore that check engine light every time it illuminates. It’s just a little light, right? What’s the worst it can do?
Ignore the check engine light at your own peril. Ultimately, it’s lit up because something’s wrong with your car, and no matter how much you try and will it into existence, that reason isn’t magically going away.
How urgent is a Transmission rebuild?
If you haven’t figured it out by now, the transmission is a critical part of your car. You need a functioning transmission, and driving around with a faulty one can cause serious damage to other parts of your car.
Don’t beat around the bush with your transmission.
