aoa, our house hold vitz99 automatic hessitates to change to second gear. If accelerated if gives a increased race sound and jerk. If i let go of pedal a little and then accelerate it changes to second gear and then gears change smoothly. Only happens on 1 to 2nd gear change. Auto transmission fluid was changed an year ago on 58 k odo. was run on cng for 4 years but now for an year running on petrol only. Hi octane helps a little.
Is it atransmission probem or the catalytic converter problem. check engine light is on for last 2 years as mechanics says it was due to cng.
I tried changing the sparks with less old ones but no use. car has been with us since 2006 but no sparks changed. it was at 30 k odo then.
Plz help. Does 99 vitz have atf filter tat i can get changed. Ive parked the car at home so no more damage occurs before its fixed.
