My Serena leaked gearbox oil at the radiator and my brother added normal ATF in the gearbox, the performance was bad and I searched on the net to verify the oil specs and remove all the oil from the gearbox and added atf synthetic as per specifications. Now the car is driving fine but when I reached 110km/h the gear change to a higher gear with full revs. From thereon the car pull very slow and had stop and after the gearbox oil dropped the car drive normal until you reach 110km/h and experience the same problem. Thanks
