P2735 — Pressure Control Solenoid "F" Intermittent

OBD2 code P2735 flags a problem with the automatic transmission control (pressure control solenoid "F" intermittent). Short, gentle driving to a shop is usually possible. Common culprits: low or degraded transmission fluid, internal mechanical wear (clutches, torque converter), failed shift or pressure control solenoid.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2735 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  5. Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2735 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2735 (parts and labor, USD, independent shop rates): Transmission rebuild or replacement: $2,500–$5,500; Replace a shift solenoid: $300–$800; Transmission fluid service: $150–$350; Valve body repair or replacement: $700–$1,500. Overall, fixing P2735 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What is the most common cause of P2735?

The most common causes are: low or degraded transmission fluid, internal mechanical wear (clutches, torque converter), failed shift or pressure control solenoid.

Is it safe to drive with P2735?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

Will P2735 clear itself?

Sometimes P2735 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How much does it cost to fix P2735?

Transmission rebuild or replacement — $2,500–$5,500; Replace a shift solenoid — $300–$800; Transmission fluid service — $150–$350; Valve body repair or replacement — $700–$1,500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does OBD2 code P2735 mean?

OBD2 code P2735 flags a problem with the automatic transmission control (pressure control solenoid "F" intermittent). Short, gentle driving to a shop is usually possible. Common culprits: low or degraded transmission fluid, internal mechanical wear (clutches, torque converter), failed shift or pressure control solenoid.

What does P2735 mean?

P2735 (Pressure Control Solenoid "F" Intermittent) is stored when self-diagnostics detect abnormal readings or behaviour of the automatic transmission control. It belongs to the powertrain (engine/transmission) category.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2735 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

Common symptoms of P2735

  • transmission stuck in one gear (limp mode)
  • harsh or delayed shifting
  • shuddering at highway speed
  • no movement in severe cases
  • slipping between gears
  • Check Engine or transmission warning light on

What causes P2735?

  • failed shift or pressure control solenoid
  • low or degraded transmission fluid
  • wiring or connector faults in the valve body harness
  • faulty transmission speed sensor
  • valve body wear

Can you drive with P2735?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.
