Common Signs of Transmission Problems

There will come a time where you will begin to experience transmission problems. Without a working transmission, it looks as like you won’t be driving anywhere anytime soon. Unfortunately, there are a lot of problems that can arise with your transmission. Especially if you have been driving for at least a few years now. A faulty transmission is one of the most expensive repairs on the market. It is for this reason you need to pay attention to the following symptoms to ensure your vehicle doesn’t fall victim to transmission problems.

Burning Smell

When it comes to your vehicle, the last thing you want to smell is something burning. There are many things that could be wrong with your vehicle, but the most like culprit is the overheating of transmission fluid. If this happens to you, make sure to get it taken care of right away before the problem worsens.

Leaking Fluid

Leaking fluids are one of the more obvious signs of a problem. The only problem will be pinpointing where the actual leak is. You can figure that out by simply placing a piece of cardboard under your vehicle to find out where it is stemming from. When you take it to the mechanic, make sure to let them know exactly where the leak is coming from.

Grinding Gears

A manual and automatic transmission issue will arise differently from each other. When it comes to a manual transmission, once you change gears you will feel a sense of grinding and sticking of the clutch. On the other hand, with an automatic car you will notice more of a rough shift when your vehicle automatically shifts to the next gear. When either of these occur, it is best to get it checked out right away.

Loud in Neutral

If you hear a bumping noise while driving, it isn’t necessarily a problem. Now, if your vehicle is making those same noises but in neutral, that can be a sign of a problem. Don’t fret too much though, this problem can usually be fixed with a simple replacement of your transmission fluid.

Identifying these problems may save you cash down the road, so don’t let them get out of hand. If you are in need of a transmission repair service, look no further than our team at H.W. Automotive Inc.

3 Major Chemical Reactions at Work In a Car’s A/C System

How does a car’s air conditioning system work? Is it virtually the same as all other A/C systems? When you put your hand on those vents, how is the air so perfectly wintry? Amazingly, there are many phenomena that function consistently every time you crank up that A/C. Learn some of the major ones below!

1. Compression

Before any of the cooling occurs, a whole lot of compression must come first. An A/C compressor typically takes a refrigerant and compresses it so that the gas is under high pressure. Once this high-pressure refrigerant moves through the high-pressure tube, it comes in contact with the condenser. Because A/C compressors are often powered by engine-accessory belts, a worn-out belt can interfere with the functionality of the compressor.

2. Condensation

Many of us know condensation as a main player in the hydrologic cycle. In an automobile’s A/C system, condensation occurs inside the A/C condenser, where the gaseous refrigerant is exchanged with the warm cabin air. Located between the grille and the radiator, the A/C condenser should be kept clean; a clogged condenser or a malfunctioning cooling fan can cause a decline in the coolness of the air. A leaking condenser would mean the loss of the refrigerant, and therefore a less effective exchange between the cool and the warm air.

3. Evaporation

After passing the high-pressure tubing, the refrigerant (in liquid form at this point due to condensation) comes across the orifice tube (also called a thermal expansion valve). Because the orifice tube permits only a little bit of refrigerant to pass at a time, the pressure is relieved, and the refrigerant transforms back into a gaseous form. This dramatic pressure reduction cools the refrigerant. And as the refrigerant evaporates back into gas form due to the hot air, the heat from the passing air gets trapped and the air becomes chilly.


Today, achieving the perfect arctic cool is possible with a simple turn of a knob or a press of a button; contrary to its effortless appearance on the outside, however, the A/C system’s inner workings are quite intricate.
