Recently bought an automatic 2.0 petrol 307cc for my dad. The car drives OK until you hit traffic and then after 20mins of traffic you can see it starts to overheat (on dash) and strugles to select first gear... I believe it is related to low/bad transmission fluid. I want to change the fluid but can not find level plug. Unfortunatly mine is not the one with a level/drain plug combined and I only can see a square drain plug on the bottom of the gearbox. Is there any way identifying gearbox code so I can google for level plug or maybe someone has experience with this?
