Need help: Cuore 2005 automatic, all gears shifting above 4000 rpm

Assala mo Alaikum

I have cuore 2005 automatic, for last one month.
From last few days, all gears are shifting on above 4000 rpm with heavy engine sound.
Is it due to gear shifting cable problem ? May i resolve this issue by myself?

Regards

is that happening only at cold engine or a constant phenomena. After warm up and if the engine sound is heavy as in struggling check if transmission cooler lines are connected correctly to the radiator. If all appears physically good then 1st change the ATF, PK DM Coure will take T-IV fluid. It may resolve the issue.
