2000 TOYOTA SIENNA User Comment / Complaint

Both problems/incidents of the automatic transmission and torque converter are tied together. the toyota sienna was less than a year old and had 9,900 miles on it. cruising at 70mph the transmission disengaged and the engine raced to 7,000rpms. pulling the sienna over to the side of the road, the transmission would not engage in any of the forward or reverse gears. the sienna had to be towed to dublin toyota for warranty repair about 65 miles away. dealer cannot tell me what failed, they were instructed to send parts intact back to the factory for post mortem diagnosis. i have opened a report with the toyota customer assistance center on 8/31, #20000-8311289. also have been speaking to the dublin toyota customer relations manager, janet fraser about finding the cause of the problem and extending the warranty to these drive train components. it has been two weeks with no response.
