P0750 on a 2017 Toyota Camry
Shift Solenoid A Malfunction
What does P0750 mean on a 2017 Toyota Camry?
P0750 is set when the TCM detects that shift solenoid A is not responding to commands — either the circuit is electrically open or shorted, or the solenoid is mechanically stuck. Shift solenoid A controls one of the hydraulic shift paths inside the valve body; depending on the transmission, "A" may control specific shifts (1-2 or 2-3) or be paired with another solenoid for upshift logic. Without a working solenoid A, the transmission cannot make those shifts and typically enters limp mode.
Symptoms on a 2017 Toyota Camry
- Check Engine Light is illuminated
- Transmission stuck in a single gear or limited gear range
- Hard, harsh, or absent upshifts
- Possible no movement in drive (if solenoid is critical to initial gear engagement)
- Engine RPM unusually high at cruise (no upshift completing)
- Reduced fuel economy
- Often paired with P0700 (transmission control malfunction)
Likely causes on a 2017 Toyota Camry
- Failed shift solenoid A (electrical or mechanical) Most commonEstimated repair: $250– $900
- Damaged solenoid wiring or external transmission connector CommonEstimated repair: $100– $500
- Contaminated transmission fluid causing valve sticking CommonEstimated repair: $150– $500
- Worn or stuck valve body causing the solenoid to lose pressure regulation OccasionalEstimated repair: $600– $2,000
- Failed TCM driver for the solenoid circuit RareEstimated repair: $500– $1,500
- Internal transmission damage (rare for P0750 alone) RareEstimated repair: $2,500– $6,500
How to diagnose this on a 2017 Toyota Camry
-
Check fluid level and condition
Always start a transmission diagnosis with fluid. Most modern transmissions require a specific procedure to check level — typically warm, level surface, engine running, selector in park. Burnt-smelling or dark fluid means clutch material in circulation; fix the underlying issue, not just the solenoid.
Tools: Vehicle-specific service procedure, Replacement fluid if needed
-
Pull all transmission codes from the TCM
P0750 alone is one repair scope. P0750 with P0731-P0734 (ratio incorrect) or P0741 (TCC stuck off) means broader transmission issues that may not resolve with a solenoid replacement alone.
Tools: Scan tool with TCM access
-
Test shift solenoid A electrically
Disconnect the external transmission connector. Find the solenoid A pin in the wiring diagram and measure resistance — typically 10–30 Ω. Infinite or near-zero means a failed solenoid. Confirm the TCM is commanding voltage during a shift attempt by back-probing while driving.
Tools: Multimeter, Wiring diagram, Back-probe pins
-
Inspect the connector for fluid contamination
A failing case seal allows transmission fluid to wick up the external wiring harness, contaminating the connector. Look for fluid inside the connector or up the harness. If found, repair the seal AND likely replace the contaminated harness section — fluid in the connector creates intermittent faults that can mimic solenoid failure.
Tools: Connector unlock tool, Flashlight
-
Drop the pan and inspect for clutch material
Brown or gritty paste on the pan magnet indicates clutch slippage somewhere in the transmission. If the solenoid is bad, that's one repair; if the pan also shows clutch material, the transmission has bigger problems and a solenoid replacement is just a stopgap.
Tools: Drain pan, New filter and gasket, Common hand tools
Known Technical Service Bulletins for the 2015-2019 Toyota Camry
Manufacturers publish Technical Service Bulletins (TSBs) when a known issue affects a specific vehicle. These bulletins come from the NHTSA database for your Toyota Camry.
- ENGINE Feb 12, 2026
This bulletin includes basic procedures for performing a rescue charge on Ni-MH high voltage (HV) batteries. This bulletin should be used in conjunction with the applicable model and model year Repair Manual while performing a rescue charge. The GRX-5100 should be used wherever the Repair Manual references the Toyota Hybrid System (THS) charger.

OBSOLETE NOTICE February 13, 2026: This bulletin is now obsolete. Please see T-SB-0009-26.
NHTSA #11029892 - UNKNOWN OR OTHER Jan 6, 2026
Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
NHTSA #11028712 - ELECTRICAL SYSTEM Jun 12, 2025
The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.
NHTSA #11020657 - STRUCTURE Dec 5, 2024
To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
NHTSA #11012743 - STRUCTURE Dec 5, 2024
The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

About the 2015-2019 Toyota Camry
The 2015-2019 Toyota Camry was commonly sold with the following powertrains: 2.5L I4, 3.5L V6, 2.5L Hybrid I4. Common trims include LE, SE, XLE, XSE.
What “solenoid A” actually does depends on the transmission
Different transmissions use different shift logic, so “shift solenoid A” controls different specific shifts:
- 4-speed automatic (older GM 4L60E, Ford 4R70W) — solenoid A typically gates the 1-2 shift
- 5-speed automatic (Ford 5R55W, ZF 5HP) — solenoid A often controls 2-3 shift
- 6-speed automatic (GM 6L80, Aisin AW) — multiple solenoids combine; A is one of several
The repair manual for the specific transmission will identify which shift A controls. The symptom set varies accordingly — some P0750 conditions strand the vehicle, others just produce harsh or skipped shifts.
Solenoid pack vs individual solenoid replacement
Modern transmissions group all shift solenoids into a single “solenoid pack” that bolts to the valve body. Replacing all solenoids at once (as a pack) is often the same labor as one solenoid alone — and prevents the other solenoids from failing shortly after as the pack ages out together. For high-mileage transmissions, pack replacement is the more economical choice.
When the solenoid is fine but P0750 still sets
Two non-obvious causes that can fool a parts-swap repair:
- External connector contaminated with fluid — looks identical to solenoid failure on a multimeter but the fluid is the real issue
- Stuck valve body sleeve — solenoid is electrically perfect but the hydraulic valve it controls is stuck open or closed; pack swap won’t help, valve body service or replacement is required
