MANUAL MODE SHIFT CONTROL OPERATION [AY6A-EL, AY6AX-EL]

id0517k3226000

• When the selector lever is shifted over from the D to M position, the M position switch in the selector lever component turns on, sending a manual mode command signal to the TCM which activates the manual mode shift control.
• When in manual mode and the selector lever is operated in the back (+) direction, the up switch in the selector lever component is turned on and an up-shift command signal is input to the TCM.

  ― The TCM, triggered by the up-shift command signal, carries out shifting by outputting an operation signal to the shift control solenoid.

• Conversely, when the selector lever is operated in the forward (–) direction, the down switch in the selector lever component turns on, and a down-shift command signal is input to the TCM.

  ― The TCM, triggered by the down-shift command signal, carries out shifting by outputting an operation signal to the shift control solenoid if the vehicle speed is less than the set speed and the gear position is 2GR or above.

• The TCM utilizes a specialized M position automatic shift diagram. Due to this, restriction of manual shift demand and automatic control of downshifting or upshifting is carried out, reducing load on the ATX, preventing engine over-rev and ensuring drive stability.
• If the engine reaches a high engine speed, the following controls are performed to protect the engine:

  1. To alert the driver that the engine speed has reached a high engine speed, the opening and closing of the throttle valve are repeated at regular intervals.
  2. The engine speed stabilizes at a lower speed than the excessive speed zone.
  3. If the engine speed reaches a high engine speed even if the above procedures are performed, a forced shift-up is performed to lower the engine speed.

Condition | Shift control | Note
--- | --- | ---
2GR→3GR up-shift command at low speed | • To reduce load on the ATX, upshifting is inhibited until vehicle reaches speed possible for upshifting | • Selector indicator “M” light and gear position indicator light flash to alert driver
3GR→4GR up-shift command at low speed
4GR→5GR up-shift command at low speed
5GR→6GR up-shift command at low speed
6GR→5GR down-shift command, above set speed | • To prevent engine over-rev, downshifting is inhibited until vehicle reaches speed possible for downshifting | • Gear position indicator light flash to alert driver
5GR→4GR down-shift command, above set speed
4GR→3GR down-shift command, above set speed
3GR→2GR down-shift command, above set speed
2GR→1GR down-shift command, above set speed
In 6GR deceleration, speed goes below coast-down set speed (deceleration down-shift) | • To assure drive stability, automatically downshifts from 6GR to 5GR | –
In 5GR deceleration, speed goes below coast-down set speed (deceleration down-shift) | • To assure drive stability, automatically downshifts from 5GR to 4GR
In 4GR deceleration, speed goes below coast-down set speed (deceleration down-shift) | • To assure drive stability, automatically downshifts from 4GR to 3GR
In 3GR deceleration, speed goes below coast-down set speed (deceleration down-shift) | • To assure drive stability, automatically downshifts from 3GR to 1GR
In 2GR deceleration, speed goes below coast-down set speed (deceleration down-shift) | • To assure drive stability, automatically downshifts from 2GR to 1GR
Wide open throttle at 90 km/h {55 mph} or less in 5GR | • To improve acceleration performance, 5GR to 4GR kickdown occurs | –
Wide open throttle at 65 km/h {40 mph} or less in 4GR | • To improve acceleration performance, 4GR to 3GR kickdown occurs
Wide open throttle at 40 km/h {24 mph} or less in 3GR | • To improve acceleration performance, 3GR to 2GR kickdown occurs

2GR Fixed Mode

• When the vehicle is stopped or the vehicle speed is 15 km/h {9.3 mph} or less, and the selector lever is moved to the + side and the gear position is in 2GR, the system enters 2GR fixed mode and the gear position is fixed in 2GR. On slippery surfaces such as snow-bound roads, forward acceleration and driving is facilitated.
• While in 2GR fixed mode and the selector lever is shifted back and forth to gears other than 2GR, the 2GR fixed mode is canceled.
