The automatic transition changes the gear ratio and plays an important role in driving your card. In the case of transmission, analysis is a fancy term for you; you can compare the process to the check-up done by a doctor. If you are sick, a doctor performs several tests to know about your illness; similarly, if you are noticing issues in your car’s performance, your mechanic checks the health of your car and engine to determine if there is any issue in the transmission diagnostic. Based on this observation, he suggests for repairs or replacements. The transmission diagnostic is quite affordable and costs between a hundred to one hundred fifty dollars
A transmission diagnostic is more of an in-depth process for older cars and can be less accurate. The modern transmission diagnostics is a more straightforward process.
Let’s look into the process in detail:
Your mechanic uses an onboard diagnostic scanner, or an OBD2 scanner to commence the process. He will plug the OBD2 scanner to your car.
- The oBD2 scanning will give the mechanic a diagnostic code.
- Each code is unique and refers to a specific problem.
- These codes make the problem fixing easier as your mechanic knows what exactly is wrong with your car.
- Your mechanic focuses on finding out the root cause of the problem and may ask you for a test drive while sensor data gets monitored and your mechanic takes the information of the performance from your car’s control unit
- If some genuine issue is detected, then you may need to repair, however, if your electronics are sending faulty signals then you may need to replace the same.
What Gets Checked?
Your mechanic checks the below things while doing transmission diagnostics
- An OBD2 scanner evaluation
- Upshift timing
- Downshift timing
- Upshift quality
- Downshift quality
- Neutral performance
- A check of your transmission fluid levels
- Initial transmission engagement
- Reverse performance
- 4X4 performance
- Passing gear
- Torque converter clutch engagement
- Shift linkage and cables
- Vacuum connections
- Harness connections
- Pan gasket
- Fluid retention
- Axle and shafts
Duration: The duration depends on whether it is just diagnostics, or there should be repairs. Depending on this the transmission diagnostics may take half a day or even a full 24 hours
When do you need a transmission diagnostics?
You need to be careful and look for the below symptoms for knowing if diagnostics needed or not:
- Burning Smell
If your transmission fluid is old, then it will produce an unpleasant smell as a result of burning
You may hear some strange sounds when your transmission fluids fail.
- Trouble Switching Gears:
You may find it difficult to switch gears, or the gears may slip as well. That calls for a warning sign and you must call your mechanic immediately.
- Transmission Fluid leaks:
If your transmission fluid is constantly leaking, then it demands your immediate attention.
You should also notice the color of the transmission fluid. If it is clean, then it will be crimson red, but if it is contaminated, then it can be dark brown or muddy depending on the amount of contamination.
If your engine is shaking or vibrating constantly then you may consider getting the transmission fluid checked
- Check Engine Light
The mechanic will utilize the OBD2 scanner to check the engine light and also the status will show on the dashboard show up on your dashboard
If you want to enjoy a smooth driving experience, then you must monitor the transmission fluid from time to time. If the transmission fluid becomes nil, then your car may fail to move and lead to severe consequences. You should monitor your dashboard and check the warning light to know the status of transmission fluid. Transmission diagnostic is an important process, and you must never neglect the same.
