Do 2004 Acura TL have transmission problems?

In general, not every 2004 Acura TL experiences transmission problems, but some owners report issues as the car ages. The most common complaints involve shifting behavior, reliability of the automatic transmission, and wear-related failures, especially as mileage increases. A well-maintained example can perform reliably, but aging components mean problems are possible.

What problems have been reported?

Across owner forums, consumer sites, and vehicle history discussions, several transmission-related patterns have surfaced for the 2004 TL. The following issues are frequently cited by owners:

• Rough or delayed shifting between gears, particularly during acceleration or highway cruising


• Transmission slipping or failing to stay engaged in Drive


• Torque converter shudder or harsh engagement, which can be noticeable as a judder during gear changes


• Warning lights or transmission fault codes appearing on the dashboard


• Leaks or low transmission fluid due to worn seals or gasket failures

These problems tend to appear as the vehicle accumulates mileage and cycles through wear-prone components. Regular maintenance and careful monitoring can mitigate some risk.

Are there recalls or service campaigns?

Honda/Acura has issued various service bulletins and recalls related to the automatic transmission family used in this generation of TL, but there has not been a widespread model-year recall specifically targeting the 2004 TL transmissions. If you own or are considering a 2004 TL, check your VIN against the NHTSA recall database and contact Acura customer service for any open campaigns or recommended service notices.

What can owners do to protect and diagnose?

Proactive maintenance and early diagnosis are key for older automatic transmissions. The following steps help reduce risk and identify issues early:

• Follow the manufacturer's recommended transmission fluid service schedule and use the specified ATF for Acura/Honda vehicles


• Have the transmission fluid and general condition checked during routine service; burnt, dark, or gritty fluid can indicate wear


• Address shifting symptoms promptly with a qualified technician to prevent more serious failures


• Ask technicians to check for software/TCM updates or related service bulletins that may address shifting concerns

Additionally, maintain a complete maintenance history and consider a pre-purchase inspection if evaluating a used 2004 TL.

Summary

In summary, while not all 2004 Acura TLs suffer transmission problems, there are credible reports of issues in older, higher-mileage examples. Regular maintenance, timely fluid changes using the correct specification, and professional diagnostics when symptoms appear can reduce risk. For current owners or prospective buyers, verify recalls for your specific VIN and consult Acura service resources for the latest guidance.

What year to avoid Acura TL?

You should avoid Acura TL years 1999–2006, particularly 2003, due to significant transmission issues. Other years to be cautious of include 2007–2008 for a more robust transmission, but still some potential problems with the Bluetooth system and mounts, and 2009–2014 for torque converter issues. The 2010 model year also experienced excessive oil consumption. 
Years with significant transmission problems 

• 1999–2006: These models, especially the 2003 and early 3rd generation (2004–2006), are known for major automatic transmission failures, slipping, and hard shifting. 
• 2004–2006: While better than earlier models, these are still prone to transmission failure and should be approached with caution. 

Years with other notable issues

• 2007–2008: These years have a more reliable transmission, but owners have reported issues with the hands-free Bluetooth draining the battery and failing. 
• 2009–2014: Some models have reported torque converter problems, which can be expensive to fix. 
• 2006: This year had several recalls and issues, including a faulty display screen, power steering leaks, and frozen rear brake calipers. 
• 2010: This model year is known for excessive oil consumption, with engines showing no leaks. 

Years to consider for better reliability 

• 2007–2008: Generally considered the most reliable, especially compared to the years immediately before them. 
• 2013–2014: Some owners report these years as very reliable. 

Other factors to consider

• Manual Transmission: If buying an automatic, aim for the 2007–2008 models. A manual transmission from any year is often a more reliable option.
• Vehicle Maintenance: Proper maintenance is crucial for any used car, especially for models with known issues. Thoroughly inspect the vehicle and review its maintenance history before purchasing. 

What are common problems with the 2004 Acura TL?

The bads: Dash cracks, HFL units are trash, spark plugs will back out over time (need to check them every 50-60k), auto windows up gets messed up, door handle caps fall off, door lock actuators go out, rear shelf rattle, side mirror rattles, front door panel rattles.

What is the transmission problem on a 2004 Acura TL?

The 2004 Acura TL's automatic transmission is known for problems like slipping, hard shifts, and potential failure, often due to overheating, a deteriorating transmission fluid, or issues with internal components like the 3rd clutch pack or pressure sensors. Other causes include a clogged transmission filter, a faulty transmission control solenoid, or low fluid pressure. Regular maintenance, including frequent transmission fluid and filter changes, and a recall for some model years can help prevent some of these issues. 
Common problems

• Slipping gears: The car may hesitate, lose power, or have trouble staying in gear. 
• Overheating: The transmission fluid can lose its viscosity, leading to increased friction and overheating. 
• Hard or delayed shifts: You might experience jerky or delayed gear changes. 
• Internal component failure: The 3rd clutch pack is prone to failure, which can block oil flow and lead to complete transmission failure. 
• Faulty sensors/solenoids: Issues with pressure sensors or solenoids can cause shifting problems and trigger check engine lights. 
• Clogged filter: A clogged or damaged transmission filter can prevent proper fluid cycling and damage internal parts. 
• Flashing D4 light: The D4 light on the dashboard may flash, which can indicate a transmission issue. 
• Burning smell: A burning odor from the transmission is a sign of overheating or fluid breakdown. 
• Noises: Whining, clunking, or buzzing noises can indicate a problem. 

How to help prevent or fix issues

• Change the transmission fluid regularly: Regular fluid and filter changes, ideally every 30,000 miles, are crucial for maintenance. 
• Check and replace the transmission filter: A clogged filter can cause serious damage, so ensure it is clean or replaced. 
• Address internal issues early: Replacing the 3rd and 4th gear pressure switches can help prevent premature failure. 
• Replace faulty solenoids: If there are issues with shifting, replacing the transmission control solenoids might resolve the problem. 
• Fix leaks immediately: If you find leaks, repair them to prevent low fluid levels. 
• Have the transmission checked: If you notice any of these symptoms, have a trusted mechanic inspect the transmission. There was also a recall for 2001–2004 vehicles for a potential internal fault, so check if your vehicle is affected.
