Transmission Download

Hello friends. I have a 2004 model 307 xt car. When I went to the master today, I told the engine that there was a buzzing sound coming from the engine when the load got on. My master said the sound came from the gearbox. The topic I asked for help, how much does it cost me to download the gearbox? I would be glad if there are people who have a transmission problem nearby and those who help.

Is the sound coming from the steering pump rushing when the load is loaded on the engine is definitely from the transmission?

1000 TL, I think, first of all, the gearbox goes down and the gears inside are looked at if it is possible to improve, but if there is no possibility to do it, the old gearbox is given and money is given and the robust gearbox is taken.

The download of the gearbox takes at least half a day, workmanship excluding parts costs around 500-600 TL

There's no trouble shifting gears in my car. There is a shortage of humming sounds that come to the engine only when in motion.

Could there be a problem in the alternator belt system? If the gearbox does not have a problem with gear shifts, maybe its oil is reduced. I wonder if you get it informed

Transmission and engine wedges may change and the master may overestimate it

The transmission ear came to my mind but does it make a buzzing sound?

We have one 206 trouble, there is no problem with the same gears, no tingling, no cortting, no transitions are very easy, but when you go on the road with the car, you shifted the gear, there is no sound.
