The 10-pace additionally has notably quicker shift overall performance than the preceding-era nine-pace transmission. For more responsiveness, the 10AT could make 4-equipment direct downshifts, consisting of from 10 to 6, or from 7 to 3, permitting brief acceleration for merging or passing. To maximize gasoline performance and reduce engine noise while cruising, tenth equipment ratio is an extremely tall 1.857:1.

Shift-By-Wire Gear Selector

The 2021 TLX makes use of a totally electronic, shift-via way of means of-twine equipment selector. Park, Neutral and Drive are decided on with the rush of a button. Reverse is chosen via way of means of pulling again a devoted switch. Indicator lighting on or subsequent to the buttons imply the mode decided on. Also, if the car is delivered to a forestall in Drive or Reverse, the machine will routinely pick out Park if the driving force's seatbelt is unbuckled and the driving force's door is opened. Steering wheel-hooked up paddle shifters allow the driving force take guide manage of transmission equipment selection.

Automatic Modes

The 10-pace computerized transmission may be operated in absolutely computerized modes: The D (or "Drive") mode is good for maximum using conditions and combines gasoline performance with clean operation and responsive energy while needed. The S (or "Sequential" mode) is supposed for greater lively or disturbing using in 1st thru eighth gears and functions greater competitive shift mapping to preserve engine speeds (rpm) better for more acceleration and pulling energy.

In D mode, the transmission consists of a sophisticated Grade Logic Control System, Shift Hold Control and Cornering G Shift Control - all of which lessen undesirable transferring and equipment hunting. The end result is wise transmission operation that optimizes gasoline performance and maintains the transmission in an appropriate equipment for using situations, providing wonderful overall performance and clean operation.

Grade Logic Control

While ascending or descending hills, Grade Logic Control alters the transmission's shift time table to lessen shift frequency and enhance pace manage, supporting to reduce driving force workload. The transmission ECU usually measures throttle position, car pace and acceleration/deceleration to decide while the car is on a hill. The shift time table is then adjusted - all through ascents to keep the transmission in decrease gears to reinforce mountaineering energy, and all through descents to offer more engine braking.

Shift Hold Control

Shift Hold Control maintains the transmission in its current (decrease) equipment ratio all through competitive using, as withinside the case of decelerating at a nook entry. Shift Hold Control leaves the chassis undisturbed via way of means of getting rid of extra transferring and guarantees that energy can be greater without delay to be had (with out a downshift) on the nook go out.

Cornering G Shift Control

Cornering G Shift Control video display units the rate of every rear wheel independently to decide while the TLX is turning. When the machine detects a enough pace differential among the rear wheels, it'll suppress any undesirable upshifts. This prevents the transmission from upshifting all through a nook that could disillusioned the chassis stability, as a result requiring downshifting once more on the nook go out while the throttle is applied.

Paddle Shifters

The Acura TLX functions twin steerage wheel-hooked up paddle shifters. Particularly beneficial in mountainous terrain or all through lively using, the paddles supply the driving force more manage over transmission operation. On lengthy downgrades, the driving force can command downshifts with the paddles that permit multiplied engine braking to lessen the weight at the brakes and assist manage the TLX's downhill pace. A-Spec fashions get paddle shifters with a steel finish.

Paddle Shifter Operation in Drive Mode

While in Drive mode, unique transmission good judgment programming lets in using the steerage wheel-hooked up paddle shifters. When the driving force operates the paddle shifters, the transmission responds to the driving force's shift command after which returns to its regular absolutely computerized mode if similarly paddle shift inputs aren't made inside some seconds, relying upon using situations. This unique good judgment makes it smooth for the driving force to command a brief downshift with out leaving the ease of Drive mode. This brief guide mode may be cancelled on the driving force's will via way of means of preserving the proper-facet paddle for 2 seconds, and the transmission will resume "Drive."

Paddle Shifter Operation in Sequential Mode (Sequential SportShift)

By deciding on the "S" position, Sequential mode is engaged. This mode gives computerized operation with greater competitive shift mapping and locks out operation of ninth and tenth gears. A pull on both of the paddle shifters locations the transmission in absolutely guide mode till some other mode of operation is chosen. A virtual show withinside the tool cluster shows which equipment the transmission is in. The Drive-via way of means of-Wire™ throttle machine creates a "blip" of the throttle to assist healthy equipment speeds even as downshifting.

Transmission Operational Backstops

To save you damage to the powertrain while the transmission is paddle shifted via way of means of the driving force, the machine will inhibit doubtlessly adverse shifts. As an brought protection measure, the Electronic Control Unit (ECU) also can reduce off gasoline to the engine to save you over-revving. If gasoline cutoff is inadequate to save you engine over-revving, as is probably viable while the car is on a steep downhill, the transmission will routinely upshift to save you damage. On downshifts, the transmission will now no longer execute a driving force command so one can over-rev the engine.

For progressed forestall-and-pass overall performance and to assist save you "lugging" the engine, the transmission will routinely downshift despite the fact that the transmission has been left in a better equipment because the car involves a forestall.

Cooperative Control

Both shift overall performance and smoothness are progressed via way of means of cooperative manage among the Drive-via way of means of-Wire™ throttle machine and the electronically managed transmission. The engine is throttled via way of means of the engine control machine all through upshifts and downshifts so the feature of the engine and transmission may be carefully choreographed for quicker, smoother transferring. As a end result, top g-forces (or "shift surprise") are decreased extensively all through upshifts and downshifts.

Front-Wheel Drive

The Acura TLX gives fashionable the front-wheel force. With its green layout and mild weight, the TLX with the front-wheel force gets EPA gasoline economic system scores of twenty-two mpg city, 31 mpg highway, 25 mpg combined. The TLX A-Spec with the front-wheel force gets EPA gasoline economic system scores of twenty-two mpg city, 30 highway, 25 mpg combined.

Super Handling All-Wheel Drive System™ (SH-AWD®)

The TLX is to be had with the fourth era of Acura's acclaimed Super Handling All-Wheel Drive™ (SH-AWD®), which step by step distributes top-quality torque now no longer handiest among the the front and rear axles, however additionally among the left and proper rear wheels for greater unique and exhilarating dealing with reaction throughout a huge sort of street situations.
