Gear slipping o r difficulty in shifting in the JAC T6 can result from several factors:

Low o r degraded transmission fluid: Old, dirty, o r insufficient transmission fluid reduces hydraulic pressure, leading to slipping o r rough gear engagement.

Worn clutch components manual transmission: A worn clutch disc, pressure plate, o r release bearing can prevent full engagement of gears, causing slippage.

Synchronizer wear: In manual transmissions, worn synchronizers can make it difficult to smoothly engage gears.

Load and driving style: Carrying heavy cargo frequently o r aggressive shifting can accelerate wear on transmission components.

Owner recommendations:

Regularly check and replace transmission fluid according to the schedule.

Inspect and adjust clutch if shifting issues appear.

Avoid overloading the vehicle beyond the manufacturer’s rated capacity.
