Transmission Friction Element Apply Time Range/Performance
Code P273A indicates that the transmission control module (TCM) has detected that a specific friction element (such as a clutch or band) is taking too long or too short to apply, or its apply time is outside the expected range. This can be caused by low transmission fluid, a worn or damaged friction element, a faulty solenoid, or internal hydraulic issues. The TCM monitors the apply time based on input from speed sensors and compares it to a calibrated value; when the deviation exceeds a threshold, this code is set.
01. Most Common Causes
- Low or contaminated transmission fluid
- Worn or burnt friction plates
- Faulty shift solenoid
- Internal hydraulic blockage or leak
02. Symptoms You Will Notice
- Harsh or delayed shifting
- Transmission slipping
- Check Engine Light illuminated
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Check transmission fluid level and condition; top off or replace if necessary.
Step 2: Scan for additional codes and perform a transmission pressure test.
Step 3: Inspect wiring and connectors to the transmission solenoids.
Step 4: Test the shift solenoid resistance and operation using a multimeter or scan tool.
Step 5: If no external issues found, remove transmission pan and inspect for debris or worn friction material.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause further damage to the transmission. Limited driving to a repair shop may be acceptable if shifting is still smooth.
How much does it cost to fix?▼
Costs vary widely: a simple fluid change may cost $50-$150, while solenoid replacement can be $200-$400. Major transmission repair can exceed $1,500.
