Reasons For A Transmission Repair Or Replacement

Why do you need a Transmission Repair or Replacement?

Your car’s transmission is basically the heart of your car – it transfers power from the engine to the front and rear wheels. Getting your transmission checked regularly by Cronulla Sutherland Automatics is vital to ensure that your vehicle operates smoothly.

What does a transmission service at Cronulla Sutherland Automatics include?

The core aspect of a transmission service is flushing out the old transmission fluid and replacing it with new transmission fluid. However, a complete transmission service should also include: examining the pan or sump pump (if possible), cleaning or replacing the filter, cleaning the pan and installing it with a new pan gasket.

Is it cheaper to repair or replace a transmission?

A transmission replacement is the more expensive option when fixing your transmission. In many cases it is referred to as “re-manufactured.” Put simply, the manufacturer will replace parts that have gone bad with modified parts. This is an option if the transmission is too damaged to even consider a rebuild.

When should I replace a transmission?

One of the most essential factors is the mileage and age of the transmission. Automatic transmissions often fail between 128,000 and 240,000 kilometres. Manual transmissions can require a service or transmission replacement even sooner, especially when routine maintenance is neglected. As a precaution to avoid hefty solutions to a faulty transmission such as paying for a transmission repair or replacement, Cronulla Sutherland Automatics recommends a gearbox service every 30,000 to 40,000 kilometres according to your individual car manual.

What is a full transmission rebuild at Cronulla Sutherland Automatics?

A complete rebuild consists of the removal and disassembly of the transmission in full. Every part is examined for wear and damage, and then it is cleaned in a special cleaning solution, or it is replaced with another part depending on the condition in which it is in. A car transmission is one of the most important aspects of a vehicle. It’s what transmits the power from the engine to the wheels. There is a wide range of car transmissions. Some are automatic, while manual transmissions in stick-shift cars require the driver to complete extra steps for the vehicle to operate effectively and efficiently.

Transmission Repair and Replacement

Where is a transmission in a car located?

Typically, a transmission is mounted onto the chassis of a vehicle in the front. If you’ve ever wondered about how a transmission operates, the process varies depending on the transmission type. Whatever type of transmission it is, the answer to what does a transmission do is to enable the gear ratio between the engine and drive wheels to adjust as the car slows down and speeds up. When a vehicle is halted, the transmission disconnects the engine from the drive wheels so that the engine can keep idling when the wheels are not in motion. Transmissions also allow quick acceleration from a stop and enable the engine to run more slowly to effectively limit wear while the vehicle is driving at consistent speeds.

Automatic Transmissions

How does an automatic transmission work? The main automatic vs. manual transmission difference is that with an automatic transmission, the process that powers a manual transmission happens within the transmission itself. Automatic transmissions typically don’t use clutches. Instead, the automatic transmission relies on a torque converter to switch gears.

Manual Transmissions

Manual transmissions have a clutch pedal and a shifter the driver uses to manually change gears. These types of transmissions consist of a set of gears along a pair of shafts, called the input and output shafts. How does a manual transmission work? With a manual transmission, the driver has to choose the proper gear and engage or disengage the clutch. The transmission uses a flywheel, clutch and pressure plate to engage and disengage the engine from the transmission.

Why would a transmission need to be replaced?

If the transmission continuously leaks fluid it will cause consistent damage to the interior parts of the mechanism. A leak that won’t stop may be caused by damaged parts or massive external transmission damage. Both of these will result in a need for a transmission repair and replacement. Many transmission fluid leaks can be solved by replacing the pan gasket, but if this service is conducted and you’re still finding puddles of red fluid underneath your vehicle, than it may be time for a transmission replacement.

Irregular Shifts/Popping out of Gear

Sporadic shifts, unnecessary shifts or the vehicle falling out of gear are all dangerous occurrences, as they prevent you from being able to safely and effectively control your car. If this ever happens to you be sure to get to Cronulla Sutherland Automatics to get the opinion of one of our mechanics as to what the best action regarding transmission repair is. Chances are, it will result in a transmission replacement.

Won’t go into gear.

The quickest and often most efficient way to repair a transmission that won’t go into gear is to replace it. While this may seem like a jump to the worst possible conclusion, this is a definite way to get your car back on the road and moving without problems again. Dancing around a transmission that has obvious issues will be an annoying and painfully drawn-out process. When you receive a transmission replacement, you’ll be back to driving much sooner.

Burnt Transmission Fluid

If the transmission is consistently overheating it will cook the transmission fluid. If you ever smell burning while your vehicle is in motion, be sure to inspect the transmission fluid reservoir. If you pull the transmission dip stick and the fluid appears blackish, and not its usual red colour, it is a sign that there is cooling issues occurring in the transmission. This may result in needing a transmission repair or replacement.
