My 2nd Gen Vitz (2008) doesn't seem to be accelerating.... when I press the accelerator, revs build up but the power doesn't go to the wheels, I think it might be a transmission slippage issue. Also the car has almost no power when climbing sloped roads. I changed the transmission oil but it didn't fix the issue. What other things can I check which can solve this problem or the only solution is a replacement of the CVT gearbox? If so, how much will that cost me?
Car is 55000km driven, idk what the original milage might be but the engine is in pristine condition.
Kindly suggest me what to do,
