It was a mistake from my side.
meri gari slope pr khaari hoti hai aur normally jab gari baand karta tha tou phele
Park pr dalkr handbreak upar karta tha
tou the load used to be on the transmission pin and when i used to shift back it used to make that noise
but now First i hold the foot brake after that i put the car in neutral phir foot brake release karke handbrake uske baad Park
If youre used to the way i used to do it phele tou shayad time lage adapt karne pr but trust me transmission duaein degi agar ap slope pr khaari karte hain car
I know many might know this already but i didnt and this was the reason why it used to make that noise
