Hôm qua em chạy cầu Phú Mỹ mới test thử cái D2 ở Cap cũ của em, đúng là có cái này xuống dốc yên tâm hơn và không phải dùng phanh. Mấy lần trước em không biết nên cứ một lúc phải rà phanh một cái, giờ biết rồi nên chỉ cần xuống số 2 là xe chạy đều đều không tăng tốc nữa.
Một số thông tin cho các bác về chế độ bán tự động:
Driver Shift Control (DSC) or Electronic Range Selection (ERS): [/b][font="arial, helvetica, sans-serif; font-size: medium; line-height: normal"]This position (M-Manual / L-Low) allows the driver to utilise the DSC/ERS system. When the shift selector lever is moved to this position, the driver may select upshifts or downshifts by using the paddle switches located on the steering wheel/shifter. An upshift is requested by pushing either + button. Refer to the vehicle owner's manual for more specific DSC/ERS information.[/font]

<h3>Manual Shift Detent Lever with Shaft Position Switch Assembly</h3>
The transmission shaft position switch assembly is a sliding contact switch attached to the manual shaft detent lever assembly inside the transmission case. The five inputs to the TCM from the transmission manual shift shaft switch assembly indicate the transmission gear selector lever position. This information is used for engine controls as well as determining the transmission shift patterns. The state of each input is available for display on the scan tool. The five input parameters represented are Signal A, Signal B, Signal C, Signal P (Parity) and Signal N (P/N Start).
<h3>Input Speed Sensor (ISS)</h3>
The input speed sensor (ISS) is a hall-effect type sensor. The ISS mounts to the transmission case assembly and connects to the control solenoid (w/body and TCM) valve assembly through a wire harness and connector. The sensor faces the 3-5-R clutch piston housing machined teeth surface. The sensor receives 8.3-9.3 volts on the ISS/OSS Supply Voltage circuit from the TCM. As the 3-5-R/4-5-6 clutch piston housing rotates, the sensor produces a signal frequency based on the machined surface of the 3-5-R/4-5-6 clutch piston housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The TCM uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.
<h3>Output Speed Sensor (OSS)</h3>
The output speed sensor (OSS) is a hall-effect type sensor. The OSS mounts to the transmission case below the control valve body assembly and connects to the control solenoid (w/body and TCM) valve assembly through a wire harness and connector. The sensor faces the Park gear machined teeth surface. The sensor receives 8.3-9.3 volts on the ISS/OSS supply voltage circuit from the TCM. As the front differential transfer drive gear assembly rotates, the sensor produces a signal frequency based on the machined surface of the Park gear. This signal is transmitted through the OSS signal circuit to the TCM. The TCM uses the OSS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.

Chỉ là thông tin thôi bác Rockman, phỏng đoán, nó thiếu những thứ này:
- Manual Shift Detent Lever with shaft position switch.
- Input speed sensor
- Output speed sensor
Vì mình phỏng đoán như thế này:
- Khi các bác chạy chế độ D (normal), khi tăng tốc, chắc chắn nó sẽ phải đọc đc speed input và output, từ đó Shift detent lever sẽ nhảy số tương ứng khi REV và Torque đạt tới ngưỡng cần sang số. Vì thế, bộ hộp số sẽ phải đầy đủ, có thể, dây kết nối các switches và sensor không đc nối, vì thế mà các bác ko sử dụng được.
