| Description of the problem | Toyota sienna le 2006 with 72,000 miles automatic broke down on the highway --- refusing to go beyond 35miles an hour and check engine light came on. The toyota dealer claimed that the transmission had to be replaced at a cost of about 5500 + and diagnosed only transmission problem. To get a second opinion, we got the vehicle towed to aamco, the transmission experts. Aamco replaced valve body, torque converter, and their standard banner kit + transmission cooling system flush and clean. Aamco asked us to be soft on the transmission for a tank of gas. Inspite of driving slowly, we noticed that the transmission change from about 1st to 2nd gear was very slow and the car had like a hiccup when trying to accelerate and exhibited vibration at higher speeds. When we took it back to aamco, they test drove the same and now claim the computer (ecm?) is not learning the gear shift and needs to be replaced. Toyota dealer claims that the 8yr/80000mile warranty on the computer is only for a manufacturing defect and refuses to acknowledge that the computer is misbehaving. There is no check engine light or error code, but the vehicle remains sluggish. We are waiting for the pricing of the ecm module and would sincerely appreciate if the problem is acknowledged and resolved by toyota. Gone are the days when toyota was a reliable car --- we are frustrated with the whole episode and unfortunately are not confident of what else needs to get replaced to get the car up and running. |
