Guys,

Is my car's jerking normal? It jerks when it is slowing down by releasing pedal, once in a while it become more serious that I can see the RPM going up and down more seriously while driving.

I managed to ALWAYS reproduce the problem by cold starting the car then switch to reverse gear.

Need you guys' help, is there anything wrong with the engine or gearbox?

Hahahaha I have this problem before. I ask the CAT team they say nothing is in there. If the coin or paper get in there it will end up land at carpet only it won't ruin your gear box. So remember don't put coins or small paper near that hole.

Do u want the technician to open up the whole center console just to take out the coin or small pcs of paper? The process of open and close at the end will make your center console to be loose at the end more vibrating sound u will hear if each time got things get inside u ask them to take out.

I am currently trying to learn polishing technique from opti team. KC the detailer hope I can learn all that from him then maybe when I become pro I can provide service to you guys. Sierra glow is at rm700 per car with 5 years warranty. I not sure how much I want to charge but seriously it is a tedious task. At least 3 and half to 4 hours time for new cars. If I master the technique already then only I will dare give out service to people. Stay tune. If got lots of member car maybe I can do opti coat cheaper.
