Auto Repairs and Servicing

Hello, my name is Walter. Over the past few months, I have been working on my car. I never used to think much about my car. I would just jump into it and hit the road. Things were fine at first, but soon I realised that things were starting to go wrong. Strange white smoke started to appear from the exhaust. Sometimes when I changed gear, I could hear a strange noise. Foolishly, I ignored all of this until my car broke down. When I got to the auto repair shop the mechanic repaired my car and then gave it a full service. As he did so, I began my auto servicing education.

Why Prompt Action Should Be Taken When Transmissions Enter Limp Mode

by Margie White

Most car systems, such as the transmission system, are now controlled by computers. Those computers can lower the performance of the transmission to a basic level if a fault is detected. This article discusses why you should act quickly to fix the transmission of your car if the system goes into "limp mode".

Reduced Fuel Economy

The "limp mode" refers to a state in which the computer controlling the transmission keeps the car in only one gear so that further damage to the system is prevented. Usually, the car will be stuck in the second or third gear during your trip. It is unwise to postpone conducting transmission repairs if your car is in this mode. This is because the car will consume more fuel for each trip since the vehicle will be unable to change to the most efficient gears for the different driving conditions.

Increased Hydraulic Pressure

The computer may also increase the pressure of the transmission fluid in order to provide maximum protection to critical components, such as the clutches and bands, from sustaining serious damage during the time when the fault in the transmission still exists. This increased transmission fluid pressure can put a heavy strain on the hose and valves that control that fluid. Those components may eventually fail if you don't quickly take action to repair the transmission of the car.

Increased Safety Risks

A car in "limp mode" is at a high risk of stalling when you least expect it. For example, the transmission can totally fail when you are driving on the highway. This sudden failure can cause the vehicle behind you to ram into your car. You will then have to deal with fixing the damage to the body of the car in addition to having the transmission repaired.

It is imperative that you note down any helpful information about the circumstances surrounding the onset of the "limp mode". For example, are there any sounds or lights that you observed before the "limp mode" was activated? Did the problem start as soon as you started the car? At What speed had you been driving when you noticed the problem? It is also helpful to provide information about any repairs that your vehicle underwent recently. This information may help the mechanic to identify the root cause of the problem quickly so that you incur a lower labour charge due to the reduced time spent on tracing the root cause of the problem.
