In the name of God, the Most Gracious, the Most Merciful. Does your Avalon have a jerk? Delay in shifting? Or does the RPM increase and the car doesn't move normally? The question that is always repeated to us: What is the cause? Gearbox or engine? The reality is that many Avalon owners replace parts without proper diagnosis, and in the end, the problem remains the same. Sometimes it's from the gearbox: Burnt oil, low oil, gearbox computer, or internal clutches. And sometimes it's from the engine itself: Spark plugs, coils, oil consumption, weak torque, or a leak that causes shifting to get confused and you feel the problem from the gearbox. 📌 The solution is with us, not guesswork. We perform computer diagnostics, test drive the car, and check the oil and the overall condition of the gearbox before any decision. If overhaul is needed: The entire job is done inside the workshop Disassembly, assembly, and inspection before and after Original parts with a clear warranty. Even if the problem is internal to the gearbox or engine, we will tell you the real cause of the fault before any work or cost. A radical and guaranteed solution And if the problem is not solved, the customer is not obligated to pay. #Avalon #Toyota #Avalon_Gearbox #Avalon_Engine #Avalon #Toyo Contact via WhatsApp or call
