One of the things that can destroy your car's transmission without warning is water.
You see, water and transmission fluid do not mix. When water gets into your transmission, it’s a disaster waiting to happen. In Nigeria, with our heavy rains and sometimes flooded roads, this is a real problem.
How Does Water Damage Your Transmission?
First, water attacks the clutch plates. These plates have a special friction material glued to them. Water dissolves this glue, causing the material to peel off. Once that happens, your transmission starts to slip, and eventually, it just won’t shift gears anymore.
Second, water causes rust inside the transmission. The internal parts are delicate, and rust can quickly destroy them. This is a very expensive problem to fix.
Third, water contaminates the fluid. Your transmission fluid is a lubricant, a coolant, and a hydraulic fluid all in one. When water mixes in, it turns the fluid into a milky, foamy mess that can’t do its job. This can cause the small passages in the transmission to get blocked.
Finally, water can damage the solenoids and valves, which are the electrical parts that control your gear changes. If these stop working, your car will struggle to shift or get stuck in one gear.
Signs of Water Damage
So, how do you know if you have a problem? Look out for these signs:
Rough Shifting: Your car jerks or makes a clunking sound when changing gears.
Slow Shifting: The car takes a long time to change gears.
Getting Stuck: The car is stuck in one gear and refuses to shift.
Milky Fluid: If you check your transmission fluid and it looks like a pink or brownish milkshake, that's a clear sign of water or coolant contamination.
What to Do
If you suspect water has entered your transmission, do not drive your car. Driving it will only make the damage worse and more expensive to repair. The best thing to do is to have your car towed to a trusted mechanic.
