Acura TL Engine Replacement in Phoenix
Two different J-series engines across two generations, with the Type-S carrying the higher-output version of each.
The Acura TL used two different J-series V6 engines across its final two generations, and the Type-S performance variant makes the engine conversation more specific than a simple generation split. The third-generation TL (2004-2008) used the J32A3, a 3.2-litre V6; the fourth-generation (2009-2014) moved to the J37A4, a 3.7-litre unit.
The Type-S is the complication. The third-generation Type-S used a higher-output version of the J32A3; the fourth-generation Type-S used a higher-output J37A4. Those are not just different tunes but carry different internal components. A standard TL engine will physically fit a Type-S but will not produce the same output, and the engine management may require attention.
The fourth-generation TL also introduced SH-AWD, Super Handling All-Wheel Drive, on certain trims. That system adds transfer case and driveshaft hardware that the front-wheel-drive cars do not have, and it affects the supporting components around the engine even though the engine itself is the same J37.
Type-S and standard are not the same engine
The Type-S used a higher-output version of each generation's engine, with different internal components and calibration. A standard TL engine will physically fit a Type-S but will not produce the same output, and the engine management may require attention. Confirm whether you are sourcing for a standard or a Type-S before ordering.
The fourth-generation TL also introduced SH-AWD on certain trims, which adds transfer case and driveshaft hardware. The engine itself is the same J37A4 between front-wheel-drive and all-wheel-drive cars, but the surrounding components differ and should be part of the conversation.
SH-AWD adds drivetrain complexity
The fourth-generation TL was offered with SH-AWD (Super Handling All-Wheel Drive) on certain trims. SH-AWD models have a transfer case and a rear driveshaft that front-wheel-drive models do not have. The J37A4 engine block is the same between the two configurations, but the transfer case, driveshaft and supporting hardware are additional parts that should be part of the ordering conversation.
When sourcing an engine for an SH-AWD TL, the engine itself is not the differentiator. What matters is whether the surrounding drivetrain components are being addressed at the same time, because a fresh engine installed alongside a worn transfer case or driveshaft is a job half done. Confirming the drivetrain configuration before ordering prevents a conversation that should have happened earlier.
What to have ready when you request a TL engine
Three facts settle most TL engine orders: the generation, whether the car is standard or Type-S, and the drivetrain configuration. The generation determines whether you need a J32 or a J37. The Type-S designation changes the internal specification and the calibration. And the drivetrain, front-wheel drive or SH-AWD, determines which supporting hardware surrounds the engine.
The fourth-generation TL has the most variables: J37 versus J32 is gone, but Type-S, SH-AWD and transmission type all need confirming. Supplying the VIN gives a supplier the generation, the trim and the drivetrain in one step, and it is the single most useful piece of information on a TL engine request.
Where Acura TL orders go wrong
- The J32A3 and J37A4 are different engines with different displacement; the generation decides which one you need.
- Type-S models use higher-output versions of each generation's engine and are not simply tuned differently from the standard car.
- SH-AWD models have additional drivetrain hardware that front-wheel-drive TLs do not have.
None of this needs to be worked out on your own. The Engine Finder asks for the year, model and trim and does the identification from there. The engine code field is optional precisely because most people do not have it.

Year, trim and ZIP is enough to start. If you have the VIN it removes the guesswork entirely.
Common questions
Is the TL Type-S engine different from the standard TL?
Yes. The Type-S used a higher-output version of the same generation's engine, with different internal components and calibration. A standard TL engine will physically fit but will not produce the same performance and may require engine management attention. Confirm whether you are sourcing for a standard or a Type-S before ordering.
Can I put a J37 in a third-gen TL?
The J37 physically fits the third-generation TL chassis but the engine management, wiring and accessory layout differ from the J32A3 the car was built with. This is a swap rather than a straightforward replacement, and it requires planning the supporting systems as a package rather than assuming a drop-in fit.
