Buckle up. This one’s a bit complicated. The input shaft is located in the transmission or in the transfer case. It’s a rotating assembly that serves to transfer power from the engine to the drive wheels. If you’re thinking that seems important, then you’re absolutely right. So, where does the seal fit into this whole equation? It seals the input shaft, which keeps fluid from escaping from the transmission or transfer case. It also keeps debris and dirt from entering the system, which you can probably guess is pretty important. The exact location of the input shaft seal varies. If it’s in the transmission, it’s usually at the front. If it’s in the transfer case, such as in a four-wheel drive vehicle, then the input shaft seal is usually located where the transmission output shaft connects to the transfer case. If you’re still following, here’s one last important piece of information. Input shaft seals are generally only present on cars with manual transmissions. Automatic transmissions have a similar seal, but it’s called a torque converter seal, or front pump seal.
A leak in your car can mean many different things. And I hope I don’t need to tell you this, but it’s usually a bad thing. One possible culprit when it comes to leaks is the input shaft seal. If your car is dripping transmission or transfer case fluid, it may be due to a busted seal that is no longer keeping the fluid in the system. And that’s bad.
Get this. When your car starts leaking fluid you might find yourself with…less fluid! A broken input shaft seal will allow transmission or transfer case fluid to escape from the system, and that means your car will be left with less transmission or transfer case fluid. If you want to be a good friend to your car, get in the habit of checking up on it. Peek inside and see how it’s doing. A good way to do this is by routinely checking the fluid levels. If the transmission or transfer case fluid level is lower than it should be, you’ve got an issue, and that issue might be an input shaft seal that didn’t show up to work.
Look, nobody likes it when their car isn’t performing well. But it happens from time to time. If your input shaft seal is busted, then your car will end up low on transmission or transfer case fluid. And when that happens, those systems simply won’t function properly. You’ll notice it when you drive, and you’ll really notice it if you leave it unattended.Get a Quote 12-Month | 12,000-Mile Warranty
If you actually read this article, then you probably don’t need this reminder, but here goes: The transmission and transfer case are extremely important. If the input shaft seal is broken, your car’s transmission or transfer case won’t function properly.
That won’t be fun initially, but it really won’t be fun down the road if you don’t get the input shaft seal replaced. Soon, you’ll end up with much bigger issues in your transmission or transfer case and…well, I think you can guess what that means for your wallet, right?
