Your car’s transmission is vital as it transfers power from the engine to the wheels. A poorly maintained car transmission relieves your car’s engine power to move or speed up. Your car revs without getting the expected response when you step on the gas. The transmission fluid allows the gears in the gearbox to shift smoothly without any audible grinding noise or tear. It is, therefore, necessary to identify transmission leaks and have them quickly repaired.
How to Identify a Transmission Leak?
A simple method of identifying a transmission fluid leak is to check beneath your car or on your driveway or garage for any dark spots or red liquid spills. Driving with a transmission fluid leak is not dangerous. However, in time the fluid leakage will cause damage to your car resulting in costly part repairs or replacement of the entire transmission system. It, therefore, is advisable to visit your local mechanic as quickly as possible to check out your vehicle. What type of leaks will you or your mechanic identify?
Types of Transmission Leaks
Transmission leaks are rooted in different parts of the transmission. The leaks source can be from: –
1. Cracked Transmission Pan Leaks
A transmission pan located beneath your car holds the necessary transmission fluid. Your car’s aluminum transmission pan can be damaged by road debris or the pan hitting a hard object like a rock as you drive. For example, a low-wheel vehicle on a rough or rocky road will not have enough clearance to avoid large rocks and thus can easily damage its transmission pan. The crack or puncture in the transmission pan will cause leakage of the transmission fluid.
2. Worn Out Transmission Pan Gasket Leaks
A Pan Gasket leak is one of the most common fluid leaks due to worn-out or loose pan bolts. The transmission pan gasket gets exposed to enormous heat and eventually can crack thus, allowing transmission fluid to leak. Additionally, the pan gaskets can leak if they were not correctly aligned or tightened during installation.
3. Cracked Transmission Cooling Lines Leaks
Transmission cooling lines transfer transmission fluid to and from the car’s transmission to a cooling chamber usually located inside a radiator. The transmission cooling lines made of rubber, steel, metal or a combination of both are located beneath the car and are susceptible to damage due to road debris or wear and tear over time. Once damaged, they need replacement to stop the leakage of transmission fluid.
4. Torque Converter Issues
A torque converter is a device located between the engine and the automatic transmission. It works together with the car’s transmission to transfer engine power to the rear wheels of an automatic car. It also pumps oil throughout the car’s transmission system. If there is a crack on the torque converter’s body or an issue with its needle bearing, the transmission fluid will leak out.
With everything considered, when you notice a transmission leak, it is not a simple matter of adding more fluid to your transmission. The more you delay having your leak fixed by a professional mechanic, the more costly the vehicle repairs.
