What Does P273A Mean?
The TCM has detected that Transmission Friction Element G (clutch pack or band) is taking too long or too short to apply during gear engagement. This indicates internal transmission mechanical wear, hydraulic pressure issues, or adaptive learning problems.
Common Causes
35%
Worn clutch friction discs or bands causing slippage and extended apply times
25%
Low or degraded transmission fluid reducing hydraulic pressure and apply force
20%
Internal hydraulic leaks at seals or piston rings reducing apply pressure to friction element G
15%
Faulty pressure control solenoids not delivering proper hydraulic pressure for element application
5%
TCM adaptive learning values corrupted requiring relearn procedure
Diagnostic Steps
1
Step 1: Check transmission fluid level and condition; look for burnt smell or discoloration indicating clutch material degradation
2
Step 2: Use scan tool to monitor apply time data for friction element G during test drives and gear changes
3
Step 3: Perform line pressure test to verify hydraulic system is providing adequate pressure for clutch application
4
Step 4: Clear adaptive learning values and perform TCM relearn procedure, then retest for improved apply times
5
Step 5: If codes persist, internal inspection required to assess clutch pack G wear, piston operation, and seal condition
Estimated Repair Cost
$400 - $3,500
Parts + labor, varies by vehicle and location
The TCM has detected that Transmission Friction Element G (clutch pack or band) is taking too long or too short to apply during gear engagement. This indicates internal transmission mechanical wear, hydraulic pressure issues, or adaptive learning problems.
The most common cause of P273A (Transmission Friction Element "G" Apply Time Range/Performance) is: Worn clutch friction discs or bands causing slippage and extended apply times
Typical repair costs for P273A range from $400 to $3,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause harsh or delayed shifting, slipping during acceleration, or flare-ups between gears. Continued operation can lead to complete transmission failure and potential loss of power while driving.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P273A to identify the root cause.
