Why car becomes draggy during upshift ??

[Lotus4712]

Got a problem here.

 

Hope pple can help.

 

Recently I feel my car have to drag longer before upshifting at 1st low speed. Once at cruising speed seems ok. Driving a G9 auto. FC also becomes higher nw. Used to get at least 12km/ltr easily. Nw only 11, something 10 + nia And I just completed my major servicing at 60,000km. Sparks and air filter changed. Using Mobil 1 0w-40. Drink Shell 95.

 

Is it a transmission problem? Or could it be something else? What is happending here, huh? Is it a big rob? I worry chg trans oil also bai sai. Cld auto gearbox inside become kor yak liao?

 

I hv been sending to Borneo for all my servicing so far. autoTrans oil was supposed to be changed at 40k. Cld it be that they cut corners and never change the oil for me ?

 

What shld i do ?

 

 

Anyone else got tis problem or heard of tis before?

 

 

Pse advise.

 

 

Thanks Many Many.

Maybe an engine compression test may help?

Could be that the torque converter is starting to go, thats why it takes longer to upshift. I doubt it would be engine problems so don't bother with a compression test.
