P273ATransmission Friction Element G Apply Time Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P273A carries the apply-time test of P2700 to P2705 on to a seventh shift element, G. The controller measures how long element G needs from command to full engagement and stores the code if this time is implausibly long or short. Only gearboxes with more than six clutches and brakes need a letter G, and no manufacturer documents P273A publicly. Ford shows how the series is used: its 10R80 bulletins (from 21-2315 onward) list apply-time codes up to P2705 for element F and none beyond, and Ford's 2012 summary explains that a ratio check cannot tell a valve fault apart from other faults in that clutch circuit. CARB requires monitoring of automatic transmission controls. A slow G apply can mean worn plates, leaking piston seals or low pressure; the driver feels flare or harsh shifts.
- What you may notice
- Engine flare or harsh shift into gears using element G
- MIL lit, possibly with ratio codes
- Fail-safe gear operation
- Likely causes
- LikelyLeaking piston seals in the apply circuit of element G
- PossiblePressure control or shift solenoid feeding element G sticking
- PossibleWorn plates or wrong clearance of element G
- RareAdaptive shift values out of range after repair or software update
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
