P0782 Code: Meaning, Symptoms, Causes & Fix

Overview

Code P0782 indicates a fault in 2-3 Shift Malfunction, typically within transmission and shift management.

Symptoms

reduced acceleration
harsh or delayed shifting
transmission warning message

Common causes

Electrical fault in the affected circuit affecting 2-3 shift malfunction
Control module logic or calibration issue
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0782

Confirm P0782 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to 2-3 shift malfunction for obvious defects.
Use freeze-frame and live data to isolate whether the issue is electrical, mechanical, or control logic.
Check for related DTCs to identify the root-cause chain before replacing parts.
After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P0782

Low: This code is low to moderate severity in most cases, but diagnosis is still recommended to avoid recurring warnings.

Can you drive with P0782?

The vehicle is often drivable with P0782, but plan a repair window to prevent repeat faults.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

Repair obvious wiring/connector faults first to prevent repeat parts replacement.
Address the root fault mode (generic) in the 2-3 shift malfunction circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0782 remains cleared under the conditions that originally set the code.

Fix options

Clear code and confirm through drive cycle.
Test component operation and replace if faulty.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$180-$650

Common mistakes when diagnosing P0782

Replacing parts without verifying voltage, ground, and signal integrity first.
Ignoring related stored/pending codes that indicate upstream faults.
Skipping post-repair verification drive cycle and readiness checks.

P0782 in common vehicles

P0782 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0782?

P0782 is commonly set by generic faults affecting 2-3 shift malfunction.

How much does it cost to fix P0782?

For P0782, repair costs are typically $180-$650 depending on exact root cause, labor rates, and part quality.

Can I clear P0782 without repair?

You can clear P0782 temporarily, but the code usually returns until the underlying fault is corrected.
