Transmission leaks occur for several reasons. Below you'll find more about the cause of those leaks, and some ways to stop them. The best way of all is to physically replace the leaking seals, but it is usually an expensive repair job.
Reason 1- Acid impregnates rubbery seals, and this causes seals to shrink, harden, and leak.
There is lots of sulfur in Transmission Fluid - and motor oil, for that matter. Some of the additives in those fluids are there to neutralize acids that form; from humidity that collects in among the fluid and oils. Moisture, plus sulfur, plus heat makes sulfuric acid - which, with heat tightens the rubbery stuff in seals - causing the leak.
Reason 2- Seal hardening wears a grove in the shaft it is surrounding. This causes a space for fluid to leak out.
Those are the two reasons and causes of engine, transmission, a/c compressors, water pumps, axles, and Power Steering seal leaks.
Most Stop leaks work because the solvent - in the additive swells the seal, and the leak stops. The swelling may not stop!
There are two bad things with solvents in any fluid or oil:
1- They make the seal gummy and weak. This often restarts the leak as the seal
disintegrates - or the solvent evaporates - and shrinking occurs again. There are
internal seals - in engines, transmissions and power steering units. It is not a good ideal to make those seals spongy. They need to be tough.
2- Solvents destroy lubricity. This increases friction and friction drag - and triples the
wear out speed. That does not sound to good for the engine or transmission to
me! Those are reasons why you should not trust solvent-type stop leaks. You can tell they are solvents by the look of being clear, and very watery - not oily.
Better Stop leaks.
Several companies make good 'stop leak' products that do not contain solvents. They work by neutralizing acids and by an ingredient called a friction modifier. These ingredients produce a controlled swell and stop seal and gasket leaks permanently.
Friction Modifiers also condition piston, bearing, valves, and gear surfaces by changing them from wear-roughen, and fast wearing, to smooth and slow wearing. That's good!
Some people have used a brand of stop leaks is not a solvent and also contains friction modifiers. They have a beneficial lubricating value to restore a seals elasticity.

Would having a leak in the transmission pan big leak stop the car from driving if all trans fluid was gone?
The transmission will not work without fluid.
97 Jeep Cherokee 8-cylinder automatic transmission fluid leak appears to be at front will a stop leak swell the seals and stop the leak?
depends how bad it is. most stop leaks are nothing more than brake fluid. old mechanics trick. ngz
Why would my 2005 Dodge Dakota transmission stop pulling all of the sudden?
There could be a transmission fluid leak. Check the seals. They may be loose or worn out.
What do I do with transmission fluid issues in my car?
First make sure it actually is a problem with the fluid by looking for things such as a puddle of fluid coming from your car, then assess the seriousness of the leak by how much came out, if minor use stop-leak and pour it directly down the tube.
How much would it cost to fix a transmission fluid leak?
Depends on where it is leaking. If it is leaking at the pan gasket, then try tightening the bolts to 20 lb/ft torque. If that doesn't work the gasket will need replacing. This is a good time to have the fluid and filter changed. If it is leaking at the seals then you can try a can of some sort of transmission stop leak. Any Auto Parts store can recommend one. May or may not stop the leak. If the leak persists and is more than a few drops a day, the transmission will need repair by a pro.

Do the products used to stop transmission leaks wor?
Generally, no. However. Sometimes the transmission "stop leak" products may allow you to get just a little more service out of a transmission, depending on the type of leak. Most transmission leaks are internal, and cause shifting problems, primarily slipping. When a transmission leaks internally, the hydraulic pressure is reduced and clutches do not properly engage. Stop leak formulas can reduce those problems and at least temporarily, restore most of the internal hydraulic pressure; but the transmission will not last long. In the process of reducing the leak, the internal seals are softened, causing them to wear out quickly. If your transmission is experiencing leaking to the outside through a seal, the results are less promising. External seals, those which prevent fluid from escaping to the outside of the transmission, fail quickly when you use a stop leak formula, and they do not usually result in leak reduction. External seal leaks are usually caused by a split or crack in the seal and stop leak formulas do not help with that. If the leak is caused by a loose or poorly fitting gasket, stop leak formulas do not help at all.
How do you stop a fluid leak from the rear of a transmission on a 2000 Chevy blazer?
change ur rear differential gasket or ur transfer case is leaking
Add transmission sealant to a 2000 Chrysler sebring?
Any stop leak additive is always a bad idea. If you do add it, make sure the fluid level is correct when done.
Is there something you can add to the transmission to stop it from leaking?
No, thay have never made anything in a can that will fix something. If you add stop leak to your transmission it will mess up the seals and you will have to have the transmission rebuilt. It would be best to just fix the leak and a whole lot cheaper.
Will it cause damage to my transmission if I put power steering stop leak in it?
Why would you put power steering stop leak in an automatic transmission in the first place? You obviously don't know what you are doing. Take it to a professional!
Your 1997 Jeep Cherokee Sport sputters after leaving a stop or sometimes idles very rough?
Perhaps you have a leak in your transmission. Check the transmission fluid while the car is running. DO NOT check any other fluids while the engine is running.
