Automatic Transmission Cooler Problems of Toyota Sienna

I was traveling at 65mph on interstate 90 east. The car while driving when I was giving gas it didnt run forward and it just stopped on the middle of the road with my kids in it. I took it to the dealer and dealer told me that the radiator pipe got corroded so the cooling oil from the transmission didnt flow properly and the transmission failed during the car running. The Toyota has safety recall of excessive corrosion for the spare tire then same thing applies as the corrosion part is underneath of the engine.

At first, I have the tire pressure indicator light continuing to lit up. Then one morning, the van was slow to response to shifting gear and acceleration. After stopping, it won't start and move into gear at all. There was no engine light being lit or warning sign. Towed to shore Toyota at mays landing, NJ. They told me that the transmission oil had all leaked out due to the burst of abrupt failure on the inlet to the radiator. They asked me to replace the radiator at a cost of $1,150. 26! after repaired, they then told me that the transmission is bad and difficult to move into gear. They quoted another $3,780 to replace the transmission. I was furious. Since that the dealer told me that the van can be driven. I was prepared to trade it in and weighing my options. The van has 133,279 miles. I drove it ok initially, however, I experienced that it was difficult to accelerate twice. After 15 miles when I stopped at a traffic light, the van just stuck- it cannot move in any of the gears at all. I towed back home. After cooling down, it was able to drive again. The new transmission fluid smelled burnt. I am wondering why: ?why the engine light was not lit up at all when the coolant temperature was so high before spoiling the whole transmission? ?why was that not even any dtc codes stored on the obdii systems at all after all these defects? ?this seemed the same problem as the sticky transmission that other customers have been complaining about, yet Toyota has not informing the customer of any actions need to be take. I have been receiving notices about the various recalls and the potential of monetary compensation, however, nothing has been realized yet. ?this seemed to be a very dangerous situations, if the van can be slowed down or stopped so drastically, the people in the vehicle could be bumped over.

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.

Consumer took vehicle for a oil change to dealership. Mechanic dicovered a oil leak underneath vehicle oil pan gasket and a leaking bolt and seal. Engine needs a seal replacements. Also, there is a transmission leak. Front brakes are grinding metal to metal. Dealership is aware of the problems.
