auto transmission diagnostics in Richardson

Automatic Transmission Fluid Checking

When they are working well, automatic transmissions are a wonderful thing. Put the gear selector at D to drive, R to go backwards and P to park when you stop and switch off the engine. When these functions fail however, there is a problem and help is needed. A-1 Quality Transmission & Auto Repair Shop does auto transmission diagnostics in Richardson. We will get to the root of the problem and take care of it.

To correctly diagnose and solve problems, familiarity and understanding of the auto transmission of a particular brand and model of a car is important. Our trained and certified auto mechanics have the skills and experience to handle auto transmission problems.

A common cause of problems and one of the first checks that will be made is the automatic transmission fluid (ATF). The fluid can leak out of the input shaft seal, the driveshaft seals, the transmission pan gasket, the ATF cooler and line connections or the torque converter. The fluid level may also go low enough to cause the transmission to become slow to engage when it is put in drive mode. This is because of gear shifts that become slow to respond or the transmission slipping when the gear selectors are being shifted. If the ATF goes very low, the car can fail to move completely. A basic auto transmission diagnostics in Richardson service is to check the fluid when it hot, with the engine idling and with parking brake set and transmission in Park. If ATF fluid is needed, it will be added to the full mark. Overfilling can aerate the fluid which can affect transmission operation.

Another common problem with ATF is leaking. The auto transmission diagnostics in Richardson check we do to establish this at A1 is to check the dipstick reading. If it is low, there is probably a leak and a look underneath will tell us where the fluid is going. If no leaks can be seen, the radiator is the next check to see if there is ATF in the coolant. It may be that the ATF cooler in the radiator is leaking, causing the fluids to get cross contaminated.

The condition of the fluid will also be checked. It may discolor and darken as it ages but a brown color or a burnt smell indicates the fuel is badly oxidized and needs to be changed. A dipstick with varnish also points to worn out ATF.

Preventive Maintenance

You can bring your car to A-1 Quality Transmission & Auto Repair not only when you need auto transmission diagnostics in Richardson but also for preventative maintenance. This will include changing the ATF and filter which will prevent most transmission problems. How often this should be done depends on how a vehicle is used. It varies from every 30,000 miles to every two years. We will add the precise ATF specified by the manufacturer who have different specifications because of different friction additives.

Another cause of auto transmission problems is transmission fault codes. The 'Check Engine' light comes on when the computer detects a problems and sets a diagnostic trouble code. Using a scan tool or code reader, we can find out whether the trouble code is from the engine, transmission or body.

Whatever the problem with your auto transmission may be, you can count on A-1 Quality Transmission & Auto Repair to diagnose it and resolve it.
