P2733 is set when the transmission control module detects that pressure control solenoid F is stuck — either not moving when commanded or remaining in a fixed position — which disrupts the hydraulic pressure needed for proper gear shifts.
The solenoid’s internal plunger or coil can stick mechanically or electrically, preventing it from responding to TCM commands.
Corrosion, chafed wires, loose pins, or a short/open in the solenoid F circuit can cause the TCM to see a stuck condition.
Insufficient fluid level or contaminated fluid can hinder solenoid movement and pressure regulation, mimicking a stuck solenoid.
Debris, wear, or a stuck valve in the valve body can prevent proper pressure distribution even if the solenoid functions.
A defective driver circuit inside the TCM can falsely indicate a stuck solenoid; this is uncommon and should be considered only after other causes are ruled out.
No. A faulty pressure control solenoid, its wiring, or fluid condition are far more common causes. PCM/TCM replacement is rarely required and should be considered only after those items have been tested and ruled out.
If the code was triggered by low, dirty, or incorrect fluid, correcting the fluid level and condition may allow the solenoid to operate normally and the code to clear after a drive cycle. However, if the solenoid itself is mechanically stuck, fluid change alone will not fix it.
Driving may be possible but you risk harsh shifts, slipping, or the transmission going into limp‑in mode, which can reduce performance and potentially cause further damage. It is advisable to have the issue diagnosed promptly.
Once the underlying problem is fixed, the code should clear after a few drive cycles when the TCM no longer detects the fault. You can also clear it with a scan tool to verify the repair.
