P2782 code meaning
Downshift Switch Circuit Intermittent/Erratic
What P2782 means
P2782 targets a downshift switch signal that flickers, bounces or vanishes for moments. No manufacturer documents P2782 publicly. The documented paddle monitors (GM's dual-clutch TCM tables of 2023/2024, Ford's TR9070 entry) cover low, high, implausible and held-too-long (P2779–P2781, P0816) without a separate dropout test, so such a fault there tends to surface under those codes. CARB's requirement to monitor transmission inputs for circuit and rationality faults is the basis for this code. A clock spring that loses contact only at certain steering angles is the classic cause, followed by a loose pin in the column connector and a minus paddle with a bouncing contact. The driver notices sporadic missed or unexpected downshifts that disappear again.
P2782 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2782
- Downshift occasionally missed
- Sporadic unexpected downshift request
Common causes of P2782
- Most likelyClock spring losing contact at certain steering angles
- PossibleLoose pin in the steering column connector
- PossibleBouncing or worn contact in the minus paddle
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2782 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 82 | The exact fault in that area. |
What to do next
- Note P2782 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2782
What does P2782 mean?
P2782 means "Downshift Switch Circuit Intermittent/Erratic". P2782 targets a downshift switch signal that flickers, bounces or vanishes for moments. It is a generic code, so it means the same on every make.
Is it safe to drive with P2782?
P2782 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2782 fail an emissions test?
P2782 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2782 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P2782 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
