Why does my auto gearbox stpo working sometimes when i go around corners and when i ref the engine it atartsto work?

Your auto gearbox may be experiencing issues due to a low Transmission Fluid level, which can affect its ability to engage properly, especially when cornering. Additionally, a faulty transmission sensor or a problem with the torque converter could cause the gearbox to malfunction under certain conditions. When you rev the engine, it may temporarily increase fluid pressure, allowing the gearbox to engage again. It's advisable to have the transmission checked by a professional to diagnose and resolve the issue.
