Tata Harrier 2022 XZA+ AT : Rubber Band Effect

Greetings BHPians

I ain a Tata Harrier 2022 XZA+ variation (Automatic Variant). The car is driven for astir 30000 kms and has conscionable completed its 2nd twelvemonth service. I constitute this taxable to question inputs/suggestions connected a contented that I person been facing. On dilatory speeds/city postulation with mild acceleration, during the cogwheel transitions betwixt 1-2 oregon 2-3, I randomly announcement "rubber-band similar effect" wherever rpm abruptly shoots upwards to ~3000-3500rpm earlier the higher cogwheel is engaged. While driving, you tin perceive the motor revving up but the cogwheel alteration is laggy.

I person had akin acquisition successful my friend's Honda Amaze CVT 2022. That said, Harrier being a Torque Converter AT gearbox, I wasn't expecting this.

This doesn't hap ever and I person ne'er experienced it connected highways. I don't retrieve having this contented from the precise beginning. I person discussed this with TASC folks successful Bangalore but they are not capable to diagnose it arsenic the contented is not reproduced ever (that excessively successful a TD with Tata SA connected the co-passenger seat). Any invaluable guidance connected however to spell astir this problem?
