What warning signs should I look out for before the transmission in my Oshan X7 fails completely?

I want to avoid a complete transmission breakdown in my Oshan X7. Are there specific early signs o r error messages that indicate serious gearbox issues? I haven’t seen any warning lights yet, but I’m experiencing mild jerks and occasional gear hesitation. Should I get it checked now o r wait for a dashboard alert?

Transmission failure often starts subtly. Early detection is key to avoiding a full breakdown. Watch for:

Warning signs:

Jerky o r rough gear changes

Delay in shifting o r hesitation during acceleration

Fluid smells burnt odor

Check Engine Light CEL o r transmission warning

Loud clunks o r grinding noises

Decline in fuel efficiency

What to do:

Have the transmission fluid level, quality, and pressure checked

Ask for TCU diagnostic scan

Don’t wait for a warning light—many failures don’t trigger alerts until damage is severe

Act early, especially during warranty period 5 years/150,000 km
