P1750 Mechanical problem in the clutch pressure control hydraulics of a Honda or Acura automatic transmission

Honda/Acura P1750 clutch pressure control solenoid

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

Owners report slipping, jerky shifting and transmission replacement with this code, but we found no source that says how far the vehicle can safely be driven.

It gets more serious if:

  • Inspect soon: The transmission slips, shifts harshly or slowly, or the engine revs without the car speeding up.

P1750 in short

On Honda and Acura automatics, P1750 means a mechanical problem in the transmission hydraulics that control clutch pressure, tied to the clutch pressure control solenoids. Owners report slipping and costly transmission work. We could not verify how far it is safe to drive, so have the transmission checked soon.

Honda and Acura automatic transmissions use pressure control solenoids to set how hard each clutch is applied. The transmission computer watches the result, and when the hydraulic side does not behave as commanded it stores P1750.

Two reference lists define the code as a mechanical hydraulic problem involving clutch pressure control solenoid valves A and B. A dealer quoted in one Odyssey complaint recommended a clutch pressure control solenoid.

Most of the owner reports we read describe 2001-2003 Odyssey, TL and MDX models whose transmissions slipped or were replaced, often with other codes such as P0730 or P1740. We found no current bulletin for this code, so treat part advice as unconfirmed until a shop tests pressure.

Pick your make

P1750 is a manufacturer-specific code: its meaning depends on who built the car.

Other makes: meaning not verified. Check with a scan tool that reads manufacturer definitions.

Most likely causes

  1. Clutch pressure control solenoid or its hydraulic circuit

    Supported by vehicle data
    Why it ranks here
    Both reference lists name the clutch pressure control solenoid valves, and a dealer recommended replacing one on a 2002 Odyssey.
    What would change this
    Rises if a pressure test shows low or erratic clutch pressure. Falls if pressures are normal.

  2. Worn internal clutches or valve body

    Supported by vehicle data
    Why it ranks here
    Several owners were told the whole transmission needed replacing after P1750 stored with ratio or slip codes.
    What would change this
    Rises if fluid is burnt or has metal debris and shifts slip. Falls if the fluid is clean and shifts are firm.

  3. Transmission computer fault

    Possible — needs testing
    Why it ranks here
    The code definition lists no computer fault, so this stays a last item after hydraulic tests.
    What would change this
    Rises only if pressure and solenoid tests pass and the code returns.
    How to test the transmission control module (tcm)

What to test first

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

  1. Read all transmission codes and note whether P0730, P1740 or P0740 are stored with P1750.

    Low riskTool: OBD-II scan tool

    • IfP1750 is stored with gear ratio or pressure switch codes

      It meansThe problem is likely inside the hydraulics; go to the shop test.

      Go to step 2

    • IfP1750 is the only code and shifts feel normal

      It meansNote it and watch for slipping; still go to the shop test.

      Go to step 2

  2. Have a transmission shop check the fluid condition and test clutch pressure and the clutch pressure control solenoids.

    Best left to a shopTool: transmission pressure gauge, scan tool

    Warning:The solenoids sit inside the transmission, so a shop should do the pressure testing.

Symptoms

  • Check engine light on
  • Slipping or engine flare between gears Gets more serious: stop and have it checked.
  • Jerky or slow shifts Gets more serious: stop and have it checked.

How to fix

  1. Do not clear the code before a shop has read it; the stored data helps find the hydraulic fault.

Parts and cost context

  • Transmission control module (TCM):Do not replace the computer unless pressure and solenoid tests point to it.

Labor varies by vehicle and shop; get a quote before you approve a repair.

Honda

  • 2002–2003 · Odyssey

    Supported by vehicle data

    Odyssey owners report P1750 with slipping, a dealer-recommended clutch pressure solenoid and transmission replacement.

Acura

  • P0730Transmission gear ratio does not match the selected gear

    Shares causes Supported by vehicle data

    Several owners had P0730 stored with P1750 on a slipping transmission.

  • P1740Lock-up or overdrive solenoid performance (Dodge) or 4th clutch pressure switch fault (Honda)

    Same system Supported by vehicle data

    One MDX readout lists P1740 fourth pressure switch failure beside P1750.
