MG HS automatic transmission overheating: Protective response after frequent starts in high temperatures

MG HS automatic transmission overheating: Protective response after frequent starts in high temperatures

Symptoms

• After frequent starts in high temperatures, transmission overheating icons/messages and an audible warning appear on the instrument panel. ^[1]

Possible causes

• Frequent starts in high ambient temperatures raise transmission temperature and trigger overheating protection. ^[1]

Checks

• Read the message severity; if "Stop safely" is displayed, stop and check whether the wait/ready-to-drive message changes. ^[1]

What to do

• Follow the "Stop safely" message, bring the vehicle to a standstill and select P to allow cooling; move off only after the instrument panel indicates that driving may continue. If there is no change after following the prompts for about 20 minutes, or the warning does not disappear, contact an MG authorised repair service immediately. ^[1]
