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.

Likely causes

Leaking piston seals in the apply circuit of element G

Pressure control or shift solenoid feeding element G sticking

Worn plates or wrong clearance of element G

Adaptive shift values out of range after repair or software update

Symptoms

Engine flare or harsh shift into gears using element G
MIL lit, possibly with ratio codes
Fail-safe gear operation
