The transmission is one of the most complex and most expensive components in your Honda Accord. It transfers engine power to the wheels through a series of gear ratios that match driving conditions — from crawling in traffic to cruising at highway speed. The Honda Accord uses a 4-speed automatic (BAXA/MAXA), 5-speed automatic (BGRA/MGRA), or 6-speed manual depending on generation and trim. When a transmission fails, replacement or rebuild is the only repair path. This guide covers every generation of Honda Accord transmissions, real replacement costs from the current used market, and how to source the right unit.
Signs Your Honda Accord Transmission Is Failing
Transmission failure rarely happens without warning. Watch for these symptoms specific to the Honda Accord:
Slipping between gears — The transmission revs up freely between shifts without a corresponding increase in vehicle speed — as if the clutch is slipping. On V6 Accords, slipping typically begins in third gear before progressing to other gears.
Delayed engagement from Park or Neutral — After shifting from Park into Drive or Reverse, there is a noticeable pause — sometimes several seconds — before the transmission engages and the vehicle moves. This indicates worn clutch packs or low hydraulic pressure.
Shudder or vibration during acceleration — A rhythmic shudder or vibration felt through the floorboard during light acceleration, particularly between 35–45 mph, indicates torque converter lock-up clutch wear. Very common on high-mileage Accord automatics.
Transmission fluid that is dark, burnt, or has a metallic smell — Healthy transmission fluid is red and slightly transparent. Dark brown, black, or fluid with a burnt odor indicates overheating and internal wear. The presence of metal particles in the fluid means internal components have been grinding.
Check engine light with transmission-related codes — Codes such as P0730 (incorrect gear ratio), P0740 (torque converter clutch solenoid), or P0780 (shift malfunction) all point to internal transmission problems. These codes should be diagnosed promptly — continuing to drive worsens the damage.
Known Transmission Issue — Honda Accord
The Honda Accord V6 automatic transmission — specifically the 4-speed unit used in 1998–2002 models and the later 5-speed unit in 2003–2007 V6 Accords — has a well-documented failure history. The primary failure mode is third gear clutch pack wear that causes slipping and eventual loss of drive. Honda issued a Technical Service Bulletin (TSB) and extended warranty on affected vehicles, but most are now well past the coverage window. If you are buying a used 6th or 7th generation V6 Accord, verify the transmission history before purchasing. The four-cylinder Accord automatic transmission is significantly more reliable and rarely fails before 180,000 miles with proper fluid maintenance.
Honda Accord Transmission Replacement Cost
Transmission replacement is one of the most significant vehicle repair expenses. Here is a realistic cost breakdown:
OptionParts CostTotal with LaborUsed / Salvage (OEM)$339–$400$739–$1100Rebuilt / Remanufactured$600–$1100$1000–$1800New OEM / Dealer Supply$1200–$2600$1600–$3200Dealer Installed (All-In)Included$2000–$4200
Current market average for a verified used Honda Accord transmission: $384.
2003–2007 Honda Accord Transmission (7th Gen, K24A4 / J30A4 V6)
The 7th gen four-cylinder Accord (K24A4) uses the highly reliable BGRA 5-speed automatic. The V6 (J30A4) uses the BGFA 5-speed automatic which has the documented third gear clutch wear issue. If sourcing a used 7th gen V6 transmission, request documented mileage and ask the seller to confirm the transmission was inspected. The 6-speed manual on the V6 is not affected by the automatic's issues.

2008–2012 Honda Accord Transmission (8th Gen, K24Z3 / J35Z2 V6)
Honda revised the V6 automatic for the 8th gen, addressing the clutch wear issue from the 7th gen. The 8th gen V6 automatic is considerably more reliable. The K24Z3 four-cylinder continued with its proven 5-speed automatic. These transmissions are the most abundant Honda Accord units in the salvage market today.

2013–2017 Honda Accord Transmission (9th Gen, K24W / J35Y V6)
The 9th gen introduced a revised 6-speed automatic for the four-cylinder and a refined 6-speed for the V6. Both are reliable units with minimal documented failure patterns. These vehicles are now entering the high-mileage range and used transmissions are increasingly available.

Used vs Rebuilt vs Remanufactured — Which Should You Buy?
Used (salvage): The most affordable option. Best value if the donor vehicle had under 80,000 miles and you are confident in the supplier's inspection process. A used transmission with 60,000–70,000 miles typically has 80,000–100,000 miles of remaining life if properly maintained.
Rebuilt: A used transmission that has been disassembled, worn components replaced, and reassembled. Quality varies enormously by shop. Ask specifically what was replaced — a quality rebuild replaces all clutch packs, seals, solenoids, and the torque converter. A cheap rebuild only replaces what failed.
Remanufactured: Rebuilt to OEM specifications on an assembly line with standardized parts replacement. Most remanufactured transmissions come with a 1–3 year nationwide warranty. More expensive than used but provides predictable, warrantied reliability.
What to Check When Buying a Used Honda Accord Transmission
Specifically request a unit with documented mileage — Honda Accord transmissions are worth verifying given the V6 automatic's known failure history.
For V6 models (2003–2007), ask the supplier to confirm the third gear clutch pack was inspected.
Confirm the torque converter is included — it must be replaced with the transmission on high-mileage units.
Check that the transmission code (stamped on the case) matches the unit your vehicle requires.
Request fluid inspection results — metal particles in the pan indicate advanced internal wear.

Installation Notes
Professional installation is required for Honda Accord transmission replacement. Labor runs 6–10 hours at a shop. The transmission mount, torque converter, and rear main seal should all be inspected and replaced as needed during this service.
Additional service items to complete at the same time:
Replace the transmission fluid and filter (included in most professional installations)
Replace the transmission mount — these wear and are often seized on high-mileage vehicles
Inspect and replace the rear main seal if leaking — access is straightforward with the transmission removed
Flush the transmission cooler lines — old fluid and debris from the failed transmission contaminates the cooler
Frequently Asked Questions
Is it worth replacing the transmission on a high-mileage Honda Accord?
For a 7th or 8th gen Accord four-cylinder with a good body and engine, yes — a quality used or remanufactured transmission is worth the investment. The K24 engine is one of the most reliable four-cylinders ever built and will outlast another transmission. For a V6 Accord with the known automatic transmission issue and high body miles, the economics are less clear — factor in the vehicle's overall value.
How often should Honda Accord transmission fluid be changed?
Honda specifies ATF-Z1 or DW-1 fluid and recommends replacement every 30,000–45,000 miles under severe use conditions. Many independent shops recommend every 30,000 miles regardless. The V6 automatic is particularly sensitive to fluid condition — burnt or contaminated fluid accelerates the clutch pack wear significantly.
Can I use a transmission from a different year Accord?
Within the same generation and drivetrain configuration (same engine and body style), transmissions are often interchangeable. However, the PCM must match the transmission's gear ratios and solenoid configuration. Mismatched combinations can cause shift quality issues or fault codes. Always verify the transmission code matches your vehicle before installing.
