Why are you changing the transmission bro????
New transmission will cost you round about 20-30k depends upon condition of transmission in market of Pindi. Also new genuine honda clutch plate + pressure plate set etc will cost you 10-12k. So total cost will be 40-45k with genuine parts replacement +Labour.
I advice you to take the reliable mechanic to mithu ka ihaata, Saddar for best collection of transmission. Also don't replace the transmission in mithu ka ihaata. They are all thieves, don't trust on them, they take out most of parts from your car.
So take your car to reliable mechanic on which you can trust 100% and ask him to replace the transmission with genuine honda parts.
