I need a relatively timely information, from someone who knows the following thing: Our Corolla (bj. 07, 68,000 km) can only be switched very laboriously since a repair on the gearbox. Even at step speed (approx. 3-5 km/h!) the first gear only goes in after a long time. Because of this problem the car was a total of 4 times in the workshop, last were replaced clutch and pressure plate, which did not create any remedy. Today the workshop called: Es w if another gear oil is tried out and the first gear can now be switched better (which means that I will find out then). But I don’t want to go there unprepared: Can Toyota use an oil with lower viscosity or is there a specification in which exactly one type is specified? I want the actual fault to be eliminated and no half-hearted solution. Do I have to be satisfied with it? Greetings eciman
