Does TSX have transmission problems?
The simplest answer is that a subset of TSX models—particularly older automatic transmissions—have reported problems, but not every car experiences them; many owners enjoy reliable performance. Overall, the TSX is regarded as a relatively reliable sedan, especially when it's well maintained.
Understanding TSX transmissions and reliability
The Acura TSX was offered with two main drivetrain configurations across its production years: a 5-speed automatic (the most common) and a 6-speed manual (available on certain trims and years). While many owners drive their TSX with trouble-free operation, there have been reports of automatic-transmission symptoms in some models, especially with higher mileage or insufficient maintenance.
Common automatic-transmission issues reported by owners and technicians include the following:
- Harsh or delayed shifting between gears, particularly during highway cruising or acceleration
- Slipping out of gear or entering a limp-home/neutral state
- Delayed or hard engagement when selecting Drive or Reverse
- Torque-converter shudder or rough shifts, especially in cold weather
- Fluid leaks or burnt-smelling/low transmission fluid due to seals or pan gaskets
- Transmission failure requiring major component replacement at higher mileages (often around 100k–150k miles, though results vary)
Note that these problems are not universal and many TSXs with automatic transmissions operate smoothly, particularly with regular maintenance and the correct fluid specification.
Causes and remedies for automatic transmissions
Owners and technicians point to a limited set of recurring issues in automatic TSX transmissions, along with standard repair strategies:
- Aging valve body and solenoids causing shift quality problems — diagnosed and rebuilt or replaced by a transmission shop
- Contaminated or degraded transmission fluid — replaced with the recommended ATF (DW-1) and, if needed, a fluid flush
- Software calibration or TCU updates from Acura/Honda — addressed via dealer service campaigns or technician updates
- Torque-converter issues — may require replacement or rebuild
- Internal wear at high mileages — may necessitate overhaul or replacement of affected components
Regular maintenance, using the correct transmission fluid and timely service, significantly reduces the likelihood of transmission problems in the TSX automatic. If symptoms appear, professional diagnosis is advised to prevent further damage.
Manual transmission notes
The six-speed manual transmission in many TSX models is generally robust, but it shares common wear-related failure points seen in compact sedans with manual gearboxes. The primary concerns are clutch-related wear and components, rather than the gearbox itself.
- Clutch slipping or a soft/heavy pedal due to wear of the clutch disc or pressure plate
- Unusual noises or failure of the release (throw-out) bearing
- Pilot bearing or input-shaft wear causing vibration or rough engagement
- Difficulties engaging gears or gear grinding due to worn synchronizers or linkage
Maintenance for the manual TSX focuses on timely clutch service and replacement when wear indicates. Using quality parts and proper installation can extend the life of the gearbox and improve shifts.
Reliability, recalls and current status
Since the TSX was discontinued after the 2014 model year, there have not been widespread, model-wide recalls focused solely on its transmission in recent years. Individual recalls or service campaigns can affect specific VIN ranges or components that interact with the drivetrain, so buyers and owners should verify recall status using the NHTSA database and check with an Acura dealer for their exact VIN.
Overall, the TSX remains a relatively reliable used-car choice, with transmission issues largely tied to maintenance history and mileage rather than year alone.
What to do if you suspect a transmission problem
If you notice transmission symptoms, act promptly to diagnose and address the issue to minimize damage and cost. Follow these steps:
- Check for open recalls or service campaigns using your VIN on the NHTSA database and Acura’s official site
- Review the vehicle’s service history for regular automatic-transmission fluid changes and any software updates
- Have the transmission fluid level and condition checked (DW-1 is typically specified for many TSX transmissions); look for signs of contamination or burnt fluid
- Get a diagnostic from a qualified technician (scan for transmission trouble codes, test the valve body/solenoids, and inspect seals and gaskets)
- If a recall or software update applies, pursue dealer service; for mechanical concerns, obtain a repair plan or a second opinion
Early diagnosis and professional maintenance can save money and extend the TSX’s transmission life. If a problem is diagnosed, address it promptly to avoid further driveline damage.
Summary
The Acura TSX generally delivers solid reliability, including its transmissions. Automatic-transmission problems tend to appear in older or higher-mileage examples and are often addressable with proper fluid maintenance, valve-body/solenoid work, or software updates. Manual transmissions are typically durable, with clutch-related wear as the main concern. Prospective buyers and current owners should verify maintenance history, check recall status for their VIN, and consult a qualified technician if symptoms arise.
