When does the gearbox fluid level drop to an unsafe level? Because puddles under the automobile indicate a gearbox system leak, this appears perplexing to the average person.
Why Is My Transmission Fluid Low But No Leak?
Is a leak necessary to drain the gearbox fluid? If that’s a question that’s been bothering you, the short answer is that there may be no obvious signs of gearbox fluid leakage under the vehicle.
But getting the fluid out of there without a leak isn’t easy. The problem, however, may be as small as a trickle that is hardly perceptible when the engine is off.
Whenever a vehicle is in motion, particularly on a road, the system is primed to distribute fluids to the places that need them. Consequently, the fluid could seep out of the system undetected during normal distribution when you’re driving.
Thus, you should probably take your vehicle in for a comprehensive examination and diagnostic, paying special attention to the parts that deal with gearbox fluid management.
You may be asking, “Why does gearbox fluid get low?” while this is happening. The following are some of the problems that could cause the gearbox fluid levels to drop:

Defective transmission oil pan
The gearbox pans of most automobiles get corroded from being exposed to salt and other harsh road factors. Corrosion of this part over time can cause fluid to leak out of the pan through microscopic pores.
The bad transmission pan gasket
The rubber gasket that seals the gearbox oil pan can become worn or damaged with time. The gearbox fluid might leak out if the pan can’t form a tight seal when any of these things happen.
Corroded or damaged fluid pipe
The gearbox lines are a standard component of any gearbox system, used to transfer fluid between the various parts of the system. Corrosion ensures that these pipelines do not have an infinite lifespan. Because of this, the rate of fluid exhaustion is sensitive to even little damage to the gearbox lines.
Defective transmission pan drain plug
Your fluid level keeping dropping could be due to a problem with the drain plug, which could be caused by a damaged O-ring, if you find that the gasket and gearbox pan are in good shape. That’s why it’s crucial to replace the O-ring every time you drain the gearbox fluid; it sits between the pan and the drain plug.

Conclusion
Low fluid levels in an automobile are almost often caused by a gearbox fluid leak. That settles the question of whether gearbox fluid can go low without a leak.
Your car’s gearbox system could eventually be damaged if you repeatedly run on low oil levels or don’t have gearbox fluid. That being said, make sure you get in touch with your mechanic as soon as possible so they can diagnose the issue and fix it.
For optimal performance, it is important to change the oil in your car’s gearbox at the specified intervals. However, please research or consult a mechanic on how to change the gearbox fluid if you have never done it before.
