P0780 on Honda by model: symptoms, diagnosis and fix
P0700 on the CR-V is a generic flag the TCM raises to light the check-engine lamp; it is almost always stored alongside a more specific transmission code (commonly P0740/P0730/P0780/P0750). On the automatic CR-V the frequent underlying cause is a failing shift solenoid or lock-up solenoid valve assembly (and, on higher-mileage or fluid-neglected units, valve-body or internal wear). When it trips, the CR-V typically drops into limp mode — locked in one gear (often 2nd/3rd) — and older 4-speed/5-speed models flash the D4 indicator. This most commonly affects the earlier automatic CR-Vs (Gen2 2002-2006 and Gen3 2007-2011) whose Honda 4-/5-speed automatics are sensitive to fluid condition and solenoid wear.
Common Symptoms
- Check-engine light with transmission warning
- Harsh, delayed, or erratic shifting
- Transmission stuck in one gear (limp mode)
- Flashing D4 indicator on the dash
- Reduced power / won't shift up
How to Fix
Do not just clear P0700 — pull the companion transmission code that specifies the fault. Check ATF level and condition first; top off or replace with genuine Honda ATF (DW-1) if burnt. Test and replace the indicated shift/lock-up solenoid assembly, and inspect TCM wiring/connectors for corrosion. If a companion code and testing point to the valve body or internal failure, that repair or a transmission rebuild is required.

The 1997-2001 (5th gen) Prelude automatic is notorious for a high premature-failure rate, well above typical Honda reliability. Failures cluster into an early death (often under ~30,000 miles) or a later slip/harsh-shift failure. Honda quietly extended the automatic-transmission warranty on 2000-2001 cars to 7 years/100,000 miles, attributing the problem to a manufacturing deviation (raw materials/workmanship) rather than design, but left 1997-1999 owners to pay for rebuilds themselves. Manual-transmission Preludes are not affected.
Common Symptoms
- Slipping / revving in neutral then jerking into gear
- High revs and hard jerk into gear before warm-up
- Hard shifts and jolts through all gears
- Delayed engagement
- Complete loss of drive
How to Fix
Confirm with a road test and fluid check (burnt fluid, metal). Servicing with genuine Honda ATF and regular drain-and-fills can extend life but does not cure a failing unit. The accepted fix is a rebuild with updated internals or replacement with a known-good remanufactured or JDM unit; many enthusiasts convert to the 5-speed manual as a permanent cure. Check for the extended-warranty coverage on 2000-2001 cars before paying out of pocket.

Frequently asked questions
What does P0780 mean on a Honda?
P0780 stands for "Shift Malfunction (Shift Error)." P0780 is a general transmission code indicating the control module detected a shift malfunction — the transmission did not change gears correctly or did not achieve the commanded gear during a shift. It is often a 'parent' code that accompanies more specific solenoid or gear-ratio codes that pinpoint which shift failed. Symptoms can include harsh, slipping, delayed, or missed shifts, and possibly limp mode. It is generally drivable short-term but should be diagnosed promptly to prevent transmission damage. On Honda it is documented across 2 models: CR-V, Prelude.
What are the most common causes of P0780?
The most common causes of P0780 are: Low, dirty, or degraded transmission fluid, Faulty shift solenoid(s), Worn internal clutches/bands or valve body wear, Wiring or connector faults in the transmission circuit, Stuck valve body passages from debris, Faulty transmission control module, Internal mechanical transmission wear. The specific cause varies by vehicle.
How much does it cost to fix P0780 on a Honda?
Published repair estimates on Honda range from $300 to $3,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
