actually repairing will cost around 5000, I found 3 people on Sinaiya capable to do it, in reality its not really repairing they said that they will open the gear box and change all the set, they said its a package coming together.
from another side the gearbox that I found will cost me 7500 its coming from a car with 85000 kms, model 2014 like my car and the car look like in good condition.
I decided to go with another gearbox, its 2500 extra but I feel its safer, repairing an automatic gearbox its not something easy as i said it depend with quality of work and the quality of the parts. so I want to avoid getting another problem in few months and repay again.
