First let me compliment you on having a manual transmission in your car. Since the advent of the automatic transmission, cars with automatics have been thought of as more luxurious and fancy. Automatic transmissions are often seen as upgrades or something you wouldn’t consider going without if you could afford it. Automatic transmissions do have their place. Places like stop and go traffic, the commuter who likes to finish breakfast in the car and maybe for those who don’t really enjoy driving all can be made easier with an automatic. But having a manual transmission can add so much to the driving experience. It gives the driver the ultimate control over his vehicle, and a good drive will always outperform the best computer controlled automatic transmission. On top of being fun to drive, manual transmissions often provide better fuel mileage and can last significantly longer than automatic transmissions.
Really only 2 things can cause a manual transmission to fail early. Poor driving habits, and a lack of good transmission fluid. Grinding gears, power-shifting and poor clutch work can all put a lot of stress on a manual transmission. Through training, or at least trial and error, most drivers get past those bad habits quickly and your manual transmission will last for years. Low fluid level however can still be a quick killer for any manual transmission no matter how skilled the driver is. Unlike an automatic transmission, manual transmissions only use the transmission fluid as a lubricant rather than a working or hydraulic fluid. Because of this, most manual transmissions simply use oil, usually called gear oil, which is similar to engine oil, just thicker. Some manual transmissions may use a different lubricant to help protect and lubricate the synchronizers. Either way, if this lubricating fluid gets lower than it should be the transmission can build heat very quickly and things can go wrong in a hurry. If a transmission is used with low fluid, bearings can be destroyed, gears can lose teeth and shafts can be destroyed. If this happens to your transmission, you will likely need more than just a simple rebuild which comes with a high price tag.
Under normal circumstances the gear oil you put in your manual transmission has no way out. Unlike your engine, the only way for the oil to get out of your transmission is to leak past a seal or gasket. Every transmission has multiple shaft seals, one at the input shaft on the engine side of your transmission and one on each of the output shafts, like the drive shaft or axle shafts. As the input and output shafts spin these seals can wear down over time. Also, if the vehicle sits unused, the seals can dry out or get distorted from sitting in one position. Also, many manual transmissions are built with the intention of being easy to rebuild. This means they are rarely one piece cases but have different sections with gaskets between them. Over time from heat and use these gaskets can also begin to leak.
It can sometimes be difficult to notice a transmission leak in your manual transmission as they often start slow and since your transmission is one of the lowest points in your car, as you drive the dripping oil will be blown away easily by the wind. A leaking transmission can be even more dangerous than leaking motor oil since you have a relatively small amount of oil in your transmission. Most Engines can hold 4-6 quarts of oil while many manual transmissions only hold 1.5-3 quarts so even a small leak can make a difference quickly.
Sealing the leak in your manual transmission doesn’t have to involve a rebuild or even pulling your transmission out of your car, which can be a big project. Even though the seals and gaskets in your transmission are leaking, they are mostly likely still good, they just need to be restored to their original size and shape.
