| Product type code | VEHICLE |
| Description of the problem | Transmission failed at speed on i-95. With van, cargo and 5 occupants at traffic speed in the right lane, the engine raced, the van dropped out of cruise control, and we drifted to a halt on the side of the road. While moving, i shifted to "4" and "3" then back to "d" with no acceleration. Had we been in any other lane, the transition would have been harder and more dangerous than it was. The engine and other van systems continued to operate normally. When we were stopped, no forward gear produced movement, though reverse worked. A check showed the transmission fluid at normal hot level, though it was darker than normal. It took an hour on the side of the road, traffic passing alongside the van very close and very fast, before a aaa tow truck got to us. After a tow to a toyota dealership, the transmission was replaced under the powertrain warranty due to a reported failure of the forward sprag. The failed transmission was retained by the dealer. |
