So hello guys im new around and i have came with some questions. So i drive a Peugeot 307sw 2008 6-speed Aisin automatic gearbox and oh boy have i had some problems with it :/ Everything started with a change of the gearbox because the first one was fried and here am i with the second hand one after spending a lot money and still doing it searching for help. The problem is when the car is in its normal working temperature (90°) its starts to behave strange, it gets confused between 2nd and 3rd and when i put it in reverse i hear a loud BANG i did read a few topics here and all i found was to change the oil but the oil is new because it was fitted in the box when the box was changed... Any ideas??? One more question in case there is no way of fixing it(because thats what im starting to think) can i swap the automatic gearbox with a 6 speed manual. Is it possible? If it is how hard is it and what kind of gearbox do i need??
