What is the reason why the Sail AMT semi-automatic cannot engage gear?

[DelLydia]

The reason why the Sail AMT semi-automatic cannot engage gear is due to faults caused by the solenoid valve, mechanical failures, slippage caused by brake clutch pressure leakage, and computer board failures. Below is relevant information about the Sail: Introduction: The Sail was the first joint-venture brand model to directly promote itself as a 'family car.' It featured ABS, dual airbags, a 1.6-liter engine, and most importantly, a precise price tag of 100,000 yuan. At the time, the Sail was the only model that could meet all these conditions simultaneously. Front Appearance: The front face of the hatchback Sail is identical in design to the sedan model, with virtually no differences. Looking at the front of the new Sail head-on, one can sense its sporty style. A wide decorative strip runs through the entire central grille, with the golden bowtie emblem embedded in it. Paired with the slightly sharp headlights and the robust front bumper, the new Sail exudes much of the sporty essence found in the Cruze.
