I had bought my van may 2,2003 with about 19,000 miles. On October 7, while driving about 30 mph, the vehicle started smoking. When I pulled into a parking stall, passerbyers were yelling that my car was on fire. Fire department extinguished the flames. An independent arson investigator said he found transmission fluid in the engine, and that it had probably been leaking since I purchased my van.

Fluid leak around the transmission pan gasket. Repaired 3 times by 2 different Toyota dealers. Easy job but maybe it is a deeper problem? transmission did not shift when cold for about 2 miles after the first and second time it was "fixed. " after the third time trying to stop the oil leak, they adjusted the throttle cable and now it seems to shift more normally in cold mornings. Since new, the left sliding manual door was hard to open from the inside. After 2 trips for "adjustments" the door is opening correctly.
