Sealing a Front Seal Transmission Leak

front seal transmission leakTransmission leaks are often silent killers of cars.  Many leaks in your vehicle will you give you an indication that the fluid level is low and is causing problems before there is any catastrophic damage done.  For example, if your engine is leaking coolant and the level gets low your vehicle will often start to overheat, but so slowly that you have time to pull over, check your coolant level, and top things off before any damage is done.  Many cars even have a low coolant light that comes on to let you know to add some coolant before the level even gets low enough to cause your car to overheat. Your engine oil also probably has a similar warning light, but your transmission does not.

If your transmission runs low on fluid it can cause serious problems.  The transmission fluid in your car has 3 very important jobs:

  • Accomplish gear changes
  • Lubricate transmission components
  • Cool transmission components

Accomplish Gear Changes

While inconsistent gear changes may be the most noticeable affect low transmission fluid will have, it is the only problem that doesn’t leave your transmission permanently damaged.  Your transmission uses pressurized transmission fluid to move internal components to change gears and if your fluid level is low, the fluid won’t reach the pressure necessary to change gears.  While this can be dangerous to drive your car like this, it won’t permanently damage the gears.

Lubricate Transmission Components

One of the most important tasks your transmission fluid has is to lubricate the components inside.  This includes the gears and the bearings which are expected, but it also lubricates the shift components like the bands and clutches.  Lastly, the transmission fluid keeps the seals in your transmission lubricated as well. Without lubrication seals like your front transmission seal can wear out more quickly and start to leak.

Cool Transmission Components

Lastly, your transmission fluid is used to cool transmission components.  Your transmission fluid is actually run through your radiator and possibly a separate transmission cooler at the front of your car to help cool the fluid so it can cool in the components inside.  If transmission fluid gets too hot it will lose its ability to properly lubricate things but it also can literally cook things inside your transmission. Your transmission has lots of different wiring and plastic components that don’t perform very well at high temperatures.  One of the things that usually doesn’t last under high temperatures is the front transmission seal. High temperatures can cause these seals to get hard and brittle causing a front seal transmission leak.

 

If you’ve got a front seal transmission leak, you’ve got 2 options to fix it.  First, can remove your transmission and replace the front seal. Second, you can use BlueDevil Transmission Sealer in your transmission to rejuvenate the front seal and stop the leak.

      Thank you for asking about your Hyundai Accent. Unfortunately, the BlueDevil Transmission Sealer is intended for larger leaks. As long as the leak is not more than a seep or lightly dripping, you would be a good candidate for the product. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!
