P2762 Torque converter clutch pressure control solenoid circuit range or performance fault

TCC pressure control solenoid circuit range/performance

Severity not verified — if the car runs badly, have it inspected

We found no maker source saying whether you can drive with P2762. Owners report it with a disabled car, the transmission stuck in one gear, and lost power on an expressway, so treat it as a transmission fault to have checked promptly.

Source: how we rate severity

P2762 in short

P2762 sets when the current the transmission computer sends to the torque converter clutch pressure solenoid does not match what it measures. The solenoid is the most common cause, then wiring. Expect a check engine light, a transmission stuck in one gear or higher revs on the highway. Get it checked soon.

The torque converter clutch locks the engine to the transmission at cruising speed. A pressure control solenoid sets how hard it clamps. The computer commands a current through that solenoid and checks what actually flows.

P2762 sets when the commanded and measured current do not match. TroubleCodes.net lists a faulty solenoid as very common, then open or shorted wiring, with throttle position sensors and the computer unlikely.

A 2010 Subaru Outback CVT owner had the car disabled by a solenoid open circuit with this code. A 2008 GMC Acadia owner read P2762 with P0700 and lost power on an expressway. GM also lists P2762 among codes technicians may find on 2011-2012 Express and Savana vans that shift erratically.

Most likely causes

  1. Faulty torque converter clutch pressure control solenoid

    Common general cause
    Why it ranks here
    TroubleCodes.net calls this very common, and the Outback owner's dealer found a solenoid open circuit and fixed it.
    What would change this
    Rises if the solenoid fails a resistance or output test. Falls if it tests in spec.
    How to test the transmission control module (tcm)

  2. Open or shorted wiring to the solenoid

    Common general cause
    Why it ranks here
    TroubleCodes.net lists open or shorted wiring as the second cause for the current mismatch.
    What would change this
    Rises if the circuit shows an open, short or damaged connector. Falls if wiring tests good.

  3. Erratic shifting on 2011-2012 Express and Savana vans

    Supported by vehicle data
    Why it ranks here
    GM PI-0690 lists P2762 among the codes technicians may find on these vans with erratic shifting. The summary does not state a cause, so this is context for those vehicles.
    What would change this
    Rises on a 2011-2012 Express or Savana with erratic shifting. Falls on other vehicles.

  4. Throttle position sensor or transmission control module

    Possible — needs testing
    Why it ranks here
    TroubleCodes.net lists both but calls them unlikely.
    What would change this
    Rises only after the solenoid and wiring test good.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read all codes from the transmission module with a scan tool and note P0740-series or other converter clutch codes stored with P2762.

    Low riskTool: scan tool that reads the transmission module

    • IfThe vehicle is a 2011-2012 Express or Savana with erratic shifting

      It meansGM has a bulletin that lists this code; ask a dealer.

      Go to step 2

    • IfOther converter clutch or solenoid codes are stored

      It meansHave the solenoid circuit tested.

      Go to step 2

    • IfP2762 alone

      It meansHave the solenoid circuit tested.

      Go to step 2

  2. Have a shop test the solenoid resistance and its circuit, and look at fluid condition.

    Best left to a shopTool: scan tool with transmission output controls, multimeter

    Warning:The solenoid is usually inside the transmission, with hot fluid and moving parts, and the vehicle may lose drive suddenly. Leave this to a shop.

Symptoms

  • Check engine light
  • Transmission stuck in 2nd or 3rd gear
  • Revs higher than normal at freeway speed because the converter clutch does not lock
  • Engine revs with no drive, or sudden loss of power Gets more serious: stop and have it checked.

How to fix

  1. Do not clear the codes before the transmission module has been read; the stored data helps the shop.

  2. Ask a dealer whether your VIN has an open bulletin or software update for erratic shifting.

Parts and cost context

  • Transmission control module (TCM):The solenoid is normally replaced as part of transmission service. Labor varies; get a quote.
