2004 Honda Accord Transmission Problems: How Common Are They and What You Can Do

Yes—especially on V6 models with the 5‑speed automatic. The 2004 Honda Accord has a documented record of automatic-transmission issues, most notably affecting V6 trims; four-cylinder automatics see problems less frequently, and manual transmissions are largely unaffected. Below is what official records, owner reports, and shop data show, along with practical steps to diagnose, maintain, and repair these transmissions in 2025.

What the Record Shows

The 2004 Accord is part of the seventh generation (2003–2007). Honda and federal safety regulators addressed a known defect in the 5‑speed automatic used with the V6: second‑gear overheating could cause gear damage and, in rare cases, lockup. In April 2004, Honda launched a safety recall (NHTSA campaign 04V176000) to add an oiling fix and, where needed, replace damaged gears. Separately, Honda issued service bulletins over the years to address torque-converter judder and harsh shifts with software updates and fluid changes. While many cars were repaired, high-mileage vehicles can still show age-related wear or lingering issues if maintenance or recall work was missed.

Which 2004 Accords Were Most Affected

Problems are not uniform across all variants. The likelihood and type of issue vary by engine and transmission pairing.

• V6 (3.0L) with 5‑speed automatic: Highest incidence of failures, including second‑gear overheating (covered by the 2004 recall), torque-converter judder, harsh or delayed shifts, and occasional outright transmission failure at higher mileage.
• Four-cylinder (2.4L) with 5‑speed automatic: Fewer issues overall, but reports exist of torque-converter lockup shudder, shift flare, and solenoid-related harshness—often improved with software updates and proper ATF service.
• Manual transmissions (both engines): Largely reliable; problems are comparatively rare and usually unrelated to the design flaws seen in the automatics.

Understanding which drivetrain you have helps set expectations: the V6 automatic is the primary concern, while the four-cylinder automatic is a secondary risk and manuals are generally solid.

Typical Symptoms Owners Report

These signs commonly indicate an Accord automatic transmission concern and warrant inspection or service.

• Shudder or vibration around 35–45 mph as the torque converter locks up (often intermittent at light throttle).
• Shift flare (engine revs rising between gears), slipping, or delayed engagement from Park to Drive/Reverse.
• Harsh 2–3 or 3–2 shifts, especially when warm, or a pronounced downshift “bump.”
• Flashing “D” indicator, Check Engine Light, and codes like P0741/P0740 (TCC), P0730 (incorrect gear ratio), or P0780 (shift malfunction).
• Burnt or dark ATF, metallic debris on the drain plug, or whining noises that rise with speed.

If you encounter these symptoms, prompt diagnosis can limit further damage and sometimes avoid a full rebuild.

Recalls, Service Bulletins, and Fixes

Honda and dealers used several remedies depending on the problem and inspection results.

• Safety recall (04V176000, issued 2004) for certain 2003–2004 V6 automatics: Added an oil jet to improve lubrication of second gear; discolored/damaged gears were replaced. Verify completion by checking your VIN at the NHTSA site or Honda’s owner portal.
• Software updates and ATF changes for judder/shift quality: Dealers updated transmission control software and replaced fluid (original ATF‑Z1 has been superseded by Honda ATF DW‑1, which is backward‑compatible).
• Torque converter replacement: Required when lockup clutch wear causes persistent shudder or related trouble codes even after fluid and software updates.
• Transmission rebuild/remanufacture: Necessary if there is significant internal wear, gear damage, or repeated failure. Reputable reman units often include updated components and improved warranties.
• Auxiliary transmission coolers and meticulous fluid maintenance: Common preventive add‑ons on V6 cars to reduce heat stress in hot climates or heavy traffic.

The correct path depends on inspection findings; many vehicles respond to software and fluid service, while others—particularly high‑mileage V6 models—may need mechanical repairs.

Preventive Maintenance and Buying Advice

Targeted checks can reveal risk early and guide smart ownership or purchasing decisions.

1. Run a VIN history: Confirm the 2004 recall was performed; review dealer records for software updates and prior transmission work.
2. Road‑test thoroughly: Look for shudder during light-throttle cruising at 35–45 mph, shift flare, harsh downshifts, or delayed engagement when cold and hot.
3. Scan for codes and live data: Check for TCC lockup slip, gear‑ratio errors, and a flashing “D.”
4. Inspect ATF: Fluid should be bright red and not burnt; service with Honda ATF DW‑1. Many technicians recommend drain‑and‑fill (not a power flush) repeated 2–3 times to refresh fluid.
5. Service intervals: Change ATF every 30,000–60,000 miles under mixed city/high‑heat use; sooner if symptoms appear.
6. Consider a pre‑purchase inspection: A specialist can assess solenoids, mounts, and internal wear indicators before you commit.

Following these steps reduces surprises and can extend the life of an older automatic transmission, especially on V6 cars.

Typical 2025 Repair Costs (U.S.)

Costs vary by region and parts choice (OEM vs. aftermarket), but these ranges are common for Accords of this era.

• ATF drain‑and‑fill (DW‑1), 2–3 cycles with new crush washers: $150–$350 total.
• Dealer software update and relearn procedures: $0–$150 (often bundled with service).
• Torque converter replacement: $700–$1,200 for the part; $500–$1,000 labor, total $1,200–$2,200.
• Solenoid/linear solenoid service or replacement: $200–$600 parts and labor.
• Full rebuild or remanufactured transmission: $2,500–$4,500 installed, depending on warranty and shop.
• Used salvage transmission: $1,200–$2,500 installed, with higher variability and risk due to unknown history.

When comparing options, prioritize warranties and installer reputation—quality control on rebuilt or reman units can vary widely.

Key Takeaways

The 2004 Accord’s automatics—especially the V6—have a known track record of issues, but many cars run reliably with proper recall completion, software updates, and disciplined fluid service. If you’re shopping, verify history and road‑test carefully; if you already own one, address early symptoms promptly to avoid larger repairs.

Summary

The 2004 Honda Accord can have transmission problems, most notably on V6 automatics tied to a 2004 recall for second‑gear overheating and long‑term torque‑converter wear. Four‑cylinder automatics see fewer issues, and manuals are largely unaffected. Confirm recall completion, keep ATF fresh with Honda DW‑1, apply software updates, and investigate shudder or shift anomalies early. Repair costs range from a few hundred dollars for fluid/service to several thousand for torque converters or full rebuilds; choosing reputable parts and shops is critical for longevity.
