Shift Solenoid "A" Circuit
Severity
high
Left alone, this one tends to take other parts with it.
Can you drive it
Not for long
Driving on this one risks further damage. Get it to a shop rather than carrying on with it.
Indicative cost (USD)
$200–$700
Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
Shift solenoid A circuit fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.
Common symptoms
- Stuck in one gear
- Harsh / missing shifts
- Check engine light

Read the full diagnostic procedureP0750 is the electrical circuit fault for Shift Solenoid A — open, shorted, or out-of-range resistance.
P0750 is the electrical circuit fault for Shift Solenoid A — open, shorted, or out-of-range resistance. Shift Solenoid A on most domestic 4-speed and 5-speed transmissions handles the 1-2 or 2-3 shift hydraulics; on 6-speeds the naming convention varies by OEM, so verify against the FSM before ordering parts.
Fluid check first as always; then the same external diagnostic flow as P0740
- unplug the case connector, inspect for corrosion, check pin alignment, dielectric grease, clear code, road test.
- If it returns, ohm out the solenoid from the case connector — most shift solenoids spec 10-40 ohms; on/off solenoids tend to land 20-30 ohms, PWM (linear) solenoids land 5-15 ohms.
- Out of spec = solenoid pack replacement on modern integrated assemblies (you rarely replace a single solenoid because they live on a shared body).
- One important caveat: a stuck-open or stuck-closed solenoid passes the electrical check but fails the performance check — P0750 is the wiring code, P0751 is the 'it's connected but not doing its job' code, so a clean P0750 with no P0751 is almost always external (harness/connector) rather than internal.

- 2002-2008Honda Accord/Odyssey 5AT throws P0750 from external shift solenoid A failure — Honda part 28400-P7W-003, $50-80 each, swap-able without pan drop.
- 2003-2009Toyota Camry V6/Sienna/Highlander with the U151E throws P0750 from internal solenoid degradation, requires pan drop, $200-300 solenoid + filter + fluid.
- 2004-2010Ford F-150/Mustang with the 4R75E uses solenoids accessible from the valve body after pan removal; P0750 there is usually corroded internal harness, $100 wiring repair + $80 solenoid.
- 2006-2012Chrysler Sebring/Avenger/200 with the 41TE throws P0750 routinely from the integrated solenoid pack — Chrysler's solenoid pack assembly with TCM, $400-700 replacement, no rebuild required.
Estimated repair$150 (external solenoid) to $1,200 (full solenoid pack + service).

How do I diagnose a P0750 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
