2005 Acura TL Transmission Overview
The 2005 Acura TL combines a 3.2L V6 engine with a five-speed automatic transmission on automatic-equipped models. The transmission transfers engine power to the front wheels and manages gear changes as the vehicle accelerates, slows down, and cruises.
If the original unit has developed a serious mechanical or hydraulic problem, a replacement may be worth considering after proper diagnosis. However, not every shifting issue means the entire transmission needs replacement. Low or incorrect fluid, electrical faults, sensors, solenoids, and other related components can also affect transmission operation.
When shopping for a used 2005 Acura TL transmission, the most important step is confirming that the replacement matches your exact vehicle. Similar-looking transmissions may have different applications or identification codes.
Need help identifying your transmission? Contact Automart with your VIN and, if available, a clear photo of the tag on your current unit. We can use these details to help narrow down the correct application before you purchase.

How to Identify the Correct Transmission
The 2005 Acura TL was available with automatic and manual transmission configurations. This page is specifically for the 3.2L five-speed automatic. The BDGA code is associated with the automatic application; the manual transmission uses a different identification code.
What to check | What to look for |
|---|---|
Year and model | 2005 Acura TL |
Engine | 3.2L V6 |
Transmission type | Automatic, not manual |
Transmission family | BDGA reference |
Tag numbers | Compare with the tag on your original unit |
VIN | Use the complete 17-character vehicle VIN |
The transmission tag provides an important reference when comparing replacement parts. Catalog listings include tag numbers such as 20021RDGA50, 20021RDGA51, and 20021RDGA52, but the exact match should be confirmed for your vehicle.
If you can’t locate the tag, don’t guess. Send your VIN and vehicle details to our team so we can help determine what needs to be verified.
What Is The BDGA Transmission?
The BDGA is an identification code associated with the five-speed automatic transmission application found in the 2005 Acura TL 3.2L. It helps parts specialists and buyers compare catalog listings and transmission assemblies.
However, a transmission code should be treated as one part of the identification process. Before buying a replacement, compare the original tag, vehicle VIN, model year, engine, and transmission configuration. This helps avoid selecting a unit simply because it appears similar or is advertised for a nearby model year.
Signs Your Transmission May Need Attention
Transmission problems can develop gradually or appear suddenly. These common symptoms may indicate that your 4L60E needs inspection, diagnosis or repair.
Delayed Engagement
A noticeable delay when shifting into Drive or Reverse can indicate a hydraulic, fluid or internal transmission issue.
Transmission Slipping
Engine RPM rises without normal acceleration, especially during gear changes or under load.
Harsh Shifting
Hard, abrupt or unusually rough shifts between gears may indicate a control or internal transmission problem.
Loss of Reverse
If Reverse stops working or engages inconsistently, the transmission and shift system should be inspected.
Unusual Noise
Whining, grinding, humming or other abnormal sounds can be signs of internal wear or damage.
Fluid Problems
Low fluid, visible leaks or contaminated transmission fluid can affect shifting and transmission operation.
Important: These symptoms do not always mean the entire transmission needs replacement. Fluid level, linkage, electrical controls, sensors and other components should be checked before choosing a replacement transmission.

Frequently Asked Questions
Learn more about the 2005 Acura TL transmission, replacement fitment, identification codes, and what to check before ordering.
Which transmission does the 2005 Acura TL 3.2L use?
The automatic-equipped 2005 Acura TL with the 3.2L V6 uses a five-speed automatic transmission and front-wheel drive. The model was also offered with a six-speed manual, so it is important to confirm your vehicle's transmission type before selecting a replacement.
BDGA is an identification code associated with the automatic application. Verify your VIN and original transmission tag before purchasing a replacement unit.
What does BDGA mean on an Acura TL transmission?
BDGA is a transmission family identification code associated with the 3.2L five-speed automatic application. It helps when comparing parts listings and identifying a possible replacement.
However, a matching code alone should not replace a full fitment check. Compare the actual tag, vehicle VIN, model year, engine, and transmission configuration before ordering.
What transmission tag numbers should I look for?
Parts catalogs list several identification references for the 2005 Acura TL 3.2L automatic application. These can help when checking your original unit against a replacement.
| Reference type | Identification |
|---|---|
| Transmission family | BDGA |
| Cataloged tag reference | 20021RDG010 |
| Cataloged tag reference | 20021RDGA50 |
| Cataloged tag reference | 20021RDGA51 |
| Cataloged tag reference | 20021RDGA52 |
These numbers are references to verify, not a guarantee that every listed unit is interchangeable. Check the actual tag and application of the replacement before purchasing.
Can I use a transmission from another Acura TL model year?
A transmission from another model year may be listed as compatible, but compatibility should not be assumed based only on the model name or engine size. Part revisions, transmission codes, and other configuration details can affect fitment.
Before buying a unit from a different year, provide your VIN and original transmission tag to the parts team. Ask for confirmation that the specific replacement is appropriate for your vehicle.
How do I find my vehicle's VIN?
On most vehicles, the 17-character VIN can be viewed through the lower windshield on the driver's side. It may also appear on the vehicle's registration and insurance documents or on a label inside the driver's door area.
Send the complete VIN carefully, checking that letters and numbers have not been mixed up. A VIN helps identify the vehicle, but the transmission tag may still be needed to confirm the exact part.
Where can I find the transmission identification tag?
The transmission identification marking or tag is located on the transmission assembly, but the exact viewing position can be difficult to access when the unit is installed. Dirt, surrounding components, or the viewing angle may make it hard to read.
If you cannot safely access the tag, do not crawl under an unsupported vehicle or remove components just to identify it. Start by sending your VIN and vehicle details, and ask a qualified technician to help locate the marking if necessary.
What are the common signs of a failing transmission?
Possible symptoms include slipping, delayed engagement into Drive or Reverse, harsh or irregular shifts, fluid leaks, unusual noises, and transmission-related warning lights. The vehicle may also struggle to accelerate normally.
These symptoms can have causes other than complete transmission failure. A technician should check fluid condition, diagnostic codes, electrical connections, sensors, solenoids, and other related systems before recommending a full replacement.
Is a used Acura TL transmission a good option?
A used transmission can be a practical replacement option when the application is correct and the unit's condition and purchase terms are suitable. It may cost less upfront than a rebuilt or remanufactured assembly, but condition and coverage vary by unit.
Ask for any available mileage information, donor-vehicle details, inspection documentation, warranty terms, and return conditions. Compare the complete cost, including shipping and installation, rather than choosing based only on the initial price.
Does the transmission come with a torque converter?
Not every transmission listing includes the same components. The torque converter, external solenoids, sensors, and other parts may be included or sold separately depending on the particular unit.
Ask the seller to confirm exactly what comes with the transmission you are considering. Get clarification on any parts required for installation so you can plan the full replacement cost.
What information do I need to request a quote?
For a useful fitment check, provide as many of these details as possible:
- Complete 17-character VIN.
- 2005 Acura TL with the 3.2L V6 engine.
- Confirmation that the vehicle has an automatic transmission.
- Transmission tag number or a clear photo of the tag, if available.
- Delivery ZIP code for shipping estimates.
You do not need to know the transmission code before contacting us. Start with your VIN and vehicle details, and the team can advise you on any additional information needed.
How much does a 2005 Acura TL transmission cost?
The cost depends on the specific unit, condition, available mileage information, included components, warranty, and shipping destination. Used, rebuilt, and remanufactured options can have different upfront prices and coverage.
Contact Automart Auto Parts for current availability and a quote. Before purchasing, confirm the final price, shipping charges, warranty coverage, return terms, and any core charge that may apply. Do not assume that the price or terms of one listing apply to another transmission.
What should be checked before installing a replacement?
Before installation, confirm the part's application and inspect the shipment for damage or missing components. Have a qualified technician follow the correct service procedures for installation, fluid type and level, and any required diagnostic or relearn steps.
The cause of the original failure should also be addressed, and relevant cooling and electrical systems should be inspected as appropriate. Correct installation and maintenance help reduce the risk of damage to the replacement unit.
Does Automart have this transmission in stock?
Inventory changes, so availability should be confirmed for the specific 2005 Acura TL 3.2L automatic application. Contact the team with your VIN and transmission details to ask about current options.
Before placing an order, confirm the exact unit, condition, included components, price, shipping, and warranty or return terms.
