The P273A: Transmission Friction Element ‘G’ Apply Time Range/Performance indicates that the transmission friction element ‘G’ is not engaging within the expected time frame, which could lead to transmission slipping or shifting delays. This issue could be caused by a faulty friction element, a problem with the transmission control module, or wiring and connector issues.
P273A – Quick Overview
| Code | Information |
|---|---|
| Meaning | P273A: Transmission Friction Element ‘G’ Apply Time Range/Performance |
| Is it serious? | Yes, this code can lead to shifting problems, slipping, or transmission overheating, potentially causing long-term transmission damage if left unresolved. |
| Possible causes | – Poor performance of transmission friction element ‘G’ – Faulty friction element or transmission control module – Wiring or connector issues |
| How to diagnose? | – Check the performance of transmission friction element ‘G’ – Inspect the control module and related wiring – Verify friction element operation – Replace faulty components as needed |
P273A Meaning
The P273A: Transmission Friction Element ‘G’ Apply Time Range/Performance code means that the transmission friction element ‘G’ is either not applying correctly or is taking too long to engage. This condition might be due to a malfunctioning friction element, issues with the transmission control module, or wiring problems. Such delays in applying the friction element can cause the transmission to slip, shift poorly, or overheat, which may eventually lead to further transmission damage.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional codes that may provide further information related to the friction element or transmission. These codes could help narrow down the exact cause of the problem. | OBD-II Scanner |
| Check Performance of Transmission Friction Element ‘G’ | Use a diagnostic tool to monitor the performance of friction element ‘G’. Compare the engagement times and performance to the manufacturer’s specifications to determine if the friction element is taking too long to apply. | Diagnostic Tool, Manufacturer Specifications |
| Inspect Transmission Control Module and Wiring | Visually inspect the transmission control module and all related wiring for any signs of wear, damage, or disconnections. Look for any signs of corrosion or shorts that could affect communication between the control module and the friction element. | Flashlight, Multimeter |
| Verify Friction Element Operation | Use the diagnostic tool to directly test the friction element ‘G’ to verify its operation. Ensure that it is able to engage and release properly without unnecessary delay. | Diagnostic Tool |
| Check Transmission Fluid Level and Quality | Verify that the transmission fluid level is correct and that the fluid is clean. Low or degraded transmission fluid can affect the performance of friction elements, causing delays in engagement. | Transmission Fluid Tester, Vehicle Owner’s Manual |
| Replace Faulty Components as Needed | If any issues are found with the friction element, wiring, or transmission control module, replace the defective components to restore proper function. | Replacement Friction Element, Wiring Repair Kit |
| Clear the Code and Test Drive | After completing the repairs, use an OBD-II scanner to clear the P273A code. Conduct a test drive to ensure that the friction element is engaging within the expected time frame and that shifting is smooth. | OBD-II Scanner |
| Recheck for Codes | Perform a final scan after the test drive to ensure that the P273A code has not returned. If the code reappears, further diagnosis may be necessary. | OBD-II Scanner |
