What Does P07A2 Mean?
Transmission friction element A is either performing below expected engagement standards or is stuck in the off (released) position. The TCM has determined that element A is not applying when commanded, or that its engagement force is inadequate. This results in failure to achieve or maintain the gear ratios that depend on element A, causing slipping, flare-ups, or no engagement.
Safety Warning
Certain gears may be completely unavailable, causing inability to accelerate properly or maintain speed. The vehicle may be undrivable if element A controls a critical gear range. Tow the vehicle to a repair facility if gear engagement is severely compromised.
Common Causes
30%
Friction element A apply piston stuck in released position due to seal failure or debris
25%
Severely worn clutch pack A friction material (no engagement force remaining)
20%
Blocked or restricted hydraulic apply passage preventing pressure buildup
15%
Pressure control solenoid failure preventing apply pressure delivery
10%
Broken return spring or snap ring allowing piston to remain disengaged
Diagnostic Steps
1
Identify which gears depend on friction element A from the clutch apply chart.
2
Attempt engagement in those gears and monitor for complete slip (no gear engagement) versus partial slip.
3
Measure line pressure in the element A apply circuit — zero or very low pressure indicates a hydraulic supply issue.
4
Check transmission fluid level and condition — severely low fluid can prevent element engagement.
5
If pressure is present but element does not engage, the piston may be stuck or the friction material may be completely worn.
6
Internal transmission inspection is required to determine if the piston, seals, or clutch pack has failed.

The most common cause of P07A2 (Transmission Friction Element "A" Performance/Stuck Off) is: Friction element A apply piston stuck in released position due to seal failure or debris
Typical repair costs for P07A2 range from $500 to $4,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Certain gears may be completely unavailable, causing inability to accelerate properly or maintain speed. The vehicle may be undrivable if element A controls a critical gear range. Tow the vehicle to a repair facility if gear engagement is severely compromised.
