Does the Acura TLX have transmission problems?
Yes—transmission problems have been reported, especially in older TLX models (roughly 2015–2020) with the earlier nine-speed automatic; the latest TLX models (2021 onward) are generally considered more reliable. Overall, reliability has improved as the lineup has evolved.
Model years and transmission configurations
Understanding how the TLX evolved helps explain where transmission issues tend to show up. Early TLX models relied on a newer generation of automatic transmissions, while newer generations introduced refinements intended to reduce shifting irregularities and improve durability.
These notes summarize the key patterns across model years and their transmissions, including where problems have been most commonly reported.
- 2015–2020 TLX models largely used a nine-speed automatic, with owners sometimes reporting shuddering at low speeds, hesitations, and abrupt or harsh shifts.
- 2021–present TLX models moved to a redesigned 10-speed automatic, with the aim of smoother, quicker shifts and better refinement in everyday driving.
- Across generations, some owners reported intermittent issues such as hesitation, downshift hiccups, or occasional transmission fault warnings, though these were not universal and often resolved with software updates or service interventions.
- Issues tended to be more commonly discussed by owners of earlier TLX generations, while newer models have generally seen fewer widespread transmission complaints.
- When problems did occur, they were frequently addressed under warranty through dealer service visits, software calibrations, or, in some cases, fluid/service adjustments.
In summary, the bulk of published concerns centers on older TLX models with the earlier automatic design; newer TLX versions have benefited from updates intended to improve shifting smoothness and reliability. However, as with any vehicle, individual experiences vary based on maintenance, driving conditions, and usage.
What Acura has done to address the issue
Manufacturers monitor customer feedback and safety databases, issuing service bulletins and recalls when necessary. For the TLX, this has included software updates to optimize shift timing, torque converter operation, and transmission control logic, as well as prompts for fluid checks and other routine maintenance. Dealers can perform these updates and inspections under warranty or through recall/service campaigns when applicable.
Prospective buyers and current owners should verify that any applicable recalls have been completed and that the vehicle’s transmission software is up to date. A well-documented service history that includes transmission-related updates and fluid services is a positive indicator of ongoing reliability.
Tips for buying or owning a TLX with potential transmission concerns
If you’re shopping for a TLX or already own one, these practical steps can help manage risk and ensure smoother operation.
- Check for complete recall and service bulletin history related to the transmission, and confirm fixes were applied by the dealer.
- Ask about the exact transmission type by model year and verify whether any software updates or calibration changes were performed.
- During a test drive, pay attention to shifting quality across all gears, including cold starts, light throttle, acceleration, and deceleration, noting any shuddering, hesitations, or harsh shifts.
- Review maintenance records for transmission fluid changes (if applicable) and other related services; ensure recommended maintenance intervals were followed.
- If you notice shifting irregularities after purchase, have a trusted mechanic diagnose the transmission promptly and consider scheduling software updates or a diagnostic check with an Acura dealer.
With careful inspection and maintenance, many TLX owners experience reliable performance, especially in the current-generation models. Being proactive about recalls, software updates, and routine fluid checks helps maximize longevity and reduce the likelihood of transmission-related issues.
Summary
The Acura TLX has had transmission-related complaints, but these are concentrated mainly in older generations with the earlier automatic transmissions. The 2021 onward TLX models employ a refined 10-speed automatic that generally delivers smoother, more reliable performance. Prospective buyers should review recall histories, confirm transmission software updates, and seek a pre-purchase inspection that focuses on the transmission system. For current owners, staying on top of dealer updates and routine maintenance remains the best defense against transmission problems.
