I have just purchased a right hand drive RAV 4 with 79k imported from Japan. Have driven about a week and shifts good no slipping or anything to cause concern. Stopped to make a delivery and engine would just rev rpms as if in neutral. Would put in park , turn off engine, restart , shift to drive, and would drive and shift up smoothly and drive a ways and it would repeat limped it home by putting in neutral to coast and shutting off and restarting engine. Fluid is full.
