Quick answer
Code P0762 is “Shift Solenoid ‘C’ Stuck On.” The transmission control module (TCM) has worked out that shift solenoid C is mechanically or hydraulically stuck applying pressure even when it is commanded off, so the transmission shifts wrong — often harsh shifts, slipping, or a drop into limp mode. The usual culprits are dirty or low fluid and debris jamming the solenoid spool, a sticking valve body, or a failed solenoid.
The P0762 trouble code means an automatic-transmission shift solenoid is stuck in the applied position, upsetting how your transmission shifts. This guide covers the symptoms, causes and fixes for P0762, and shows where a bi-directional scan tool like the iCarsoft CR Max P lets you command the solenoid and read live gear data to confirm the fault.
1What Does the P0762 Code Mean?
P0762 is a generic powertrain DTC set when the TCM detects that shift solenoid C is stuck on — it keeps applying line pressure even when commanded to release. Solenoid C is the third shift solenoid in an A/B/C set and on many transmissions feeds the reverse and 3rd/4th clutch circuits, so lower gears can feel normal while reverse and the upper gears misbehave. This is a mechanical/hydraulic “stuck” fault, distinct from the electrical code P0763.
2Symptoms of the P0762 Code
- Check engine light, often with a transmission warning lamp.
- Harsh, erratic or incorrect shifts — especially into reverse, 3rd or 4th.
- Transmission slipping or binding in gear.
- Drop into limp mode (locked in one gear).
- Transmission overheating.
- Reverse or 3rd/4th not engaging properly.
- Reduced fuel economy.
3Common Causes of the P0762 Code
- Low, dirty or contaminated transmission fluid.
- Clogged transmission filter restricting flow.
- Debris jamming the solenoid spool — the most common true “stuck” cause.
- A sticking or failed shift solenoid C.
- Worn or sticking valve body / blocked hydraulic passages.
- Corroded or damaged solenoid connector or wiring.
- Internal transmission damage or a faulty TCM (least common).
4How Serious Is P0762? Can You Keep Driving?
Don't keep driving on P0762. A solenoid stuck on makes two clutch circuits fight each other, which overheats the fluid, glazes clutches and quickly turns a sensor-level fault into mechanical damage — and the transmission will often drop into limp mode. A short, gentle drive to a shop is fine; sustained driving risks an expensive rebuild.
5How to Diagnose the P0762 Code
Accurate diagnosis is about confirming whether the solenoid actually responds:
- A bi-directional scan tool such as the iCarsoft CR Max P to pull all codes and note whether P0762 appears alone or with electrical or gear-ratio codes.
- Check fluid level and condition first — burnt smell, dark color or metal particles.
- Watch live data: commanded vs actual gear, solenoid C state, gear-ratio PIDs and fluid temperature.
- Use the tool to command solenoid C on and off — a stuck spool won't react.
- Measure solenoid resistance and inspect the connector and harness for corrosion.
6Steps to Fix the P0762 Error Code
- Correct the fluid level and condition; if dirty or burnt, drain, refill with OEM-spec fluid and replace the filter.
- Clear the code and road-test to see if P0762 returns.
- Inspect and repair the solenoid C connector and wiring; clean any corrosion.
- Bi-directionally actuate solenoid C; if it doesn't respond mechanically, drop the pan.
- Remove and clean, or replace, the stuck shift solenoid C.
- Inspect and clean the valve body and hydraulic passages; replace it if a bore is worn.
- Reassemble, refill, relearn shift adaptives, clear codes and verify with a road test.
7Why Correct Shift-Solenoid Control Matters
The TCM relies on shift solenoids switching cleanly on and off to route hydraulic pressure to the right clutches at the right instant. When solenoid C stays applied, two clutch circuits can work against each other — that overheats the fluid, glazes the clutches and turns a quick sensor-level fix into mechanical damage. Keeping the solenoids responsive and the fluid clean is what protects the whole gearbox.
8Which iCarsoft Tool to Use
The iCarsoft CR Max P is well suited to a P0762. Beyond reading and clearing codes across all systems, its bi-directional control lets you command shift solenoid C while you watch commanded-vs-actual gear and gear-ratio data live — so you can tell a truly stuck solenoid from a fluid or valve-body problem before anything comes apart.
With CAN-FD support and coverage for 58 vehicle makes, it also confirms the transmission shifts correctly again after the repair.

10Prevention & Regular Maintenance
- Change transmission fluid and filter on the OEM schedule — sooner if you tow or run in heat.
- Use only the manufacturer-specified fluid type.
- Address shift complaints and other transmission codes early, before debris spreads.
- Fit or maintain a transmission cooler if you tow.
- Fix fluid leaks promptly to keep level and pressure correct.

12P0762 — Frequently Asked Questions
Can I drive with a P0762 code?
Only briefly and gently to a shop. Sustained driving overheats the fluid and burns clutches, so it's best not to keep driving on it.
Is P0762 the solenoid or the fluid?
“Stuck” faults are most often debris or dirty fluid jamming the solenoid spool rather than a failed coil — always check the fluid first.
What's the difference between P0762 and P0763?
P0762 is the solenoid mechanically or hydraulically stuck on; P0763 is an electrical circuit fault on the same solenoid C.
Will a fluid change fix P0762?
Sometimes, if it's caught early and the cause is contamination. It won't fix a physically failed solenoid or a worn valve body.
How do I reset the P0762 code?
Fix the underlying fault first, then clear the code with a scan tool such as the iCarsoft CR Max P and confirm it stays off after a road test.
