One thing's for sure. we shouldn't start buying the automatics because it will take a while for the mechanics to really understand the system. More over, the cost of a bad transmission far exceeds the benefits, if any ! Here is what I suggest, see if you can get a manual gearbox installed and get the prosmatic transmission removed all together. That would be a good solution unless ofcourse you plan on selling it soon , then you should keep everything stock (the way the car was made at factory).
best of luck. May Allah help you in your endevour.
