There are a lot of people out there that give less attention to the transmission of their car. They fail to give their transmission the necessary care it needs until one major fault arises or when it finally packs up.

One of the routine maintenance of a car’s transmission that is most times overlooked by some people is knowing when to change the transmission oil. The transmission oil might be present in the car and even up to the prescribed level but may contain too much dirt or sludge that will cause the transmission misbehave.

We are about to list the signs your car is likely to give to indicate your transmission is dirty and requires to be flushed.

These are the 5 signs to tell you need to flush your transmission

1. Surging of the Vehicle:

When your vehicle’s transmission is polluted with a lot of dirt and contaminants, and needs a transmission flush, you may notice inexplicable surging of your vehicle. Because your car’s dirty transmission does not allow for adequate transmission fluid flow, your vehicle may tend to jump or surge forward and fall backwards for no good reason. This is caused by inconsistent flow of clean transmission fluid that is needed to ensure smooth operation of the gears and other moving parts inside the transmission bell housing.

2. Delay in Vehicle Movement:

Another sign that your vehicle may have contaminated transmission fluid is when the vehicle stalls for one or two seconds before moving after having been put in gear. If there are no other problems with the transmission, a transmission flush may help.

3. Grinding and strange noises from the transmission:

A transmission that is due for oil change may start making grinding or strange noises. This noise tends to be significant when the transmission is contaminated with dirt, grease and sludge. At this point, the transmission displays symptoms very similar to inadequate level of transmission fluid.

4. Sluggish response while shifting gears:

On a normal operating condition of the transmission, the transition from one gear to another is often smooth. When your transmission is not clean and contains much dirt or sludge, you’ll get sluggish response in the transmission.

This could mean your car will start changing gear more quickly or too late when you drive.

For manual transmission, you may find it hard to change gears at all.

5. Slipping gears:

The effect of dirty transmission can also result in slipping gears. Very low transmission fluid can also cause this. Contaminated fluids will cause lack of hydraulic power and could make gear slip.

When you start noticing any or all these signs in your car, it may mean that your transmission needs to be flushed. You will need to take your car to a professional to flush off the old fluid and replace with the RECOMMENDED fresh fluid.

Please, endeavour to use the Transmission fluid recommended by your car manufacturers. It will save you a whole lot of troubles.
