Honda hit the road first with its gas-engine/electric-motor combo called the Insight, but it was Toyota that pioneered the “Hi Voltage Battery” technology and used it in its Prius vehicle. Ford broke ground by producing the first hybrid SUV with its 2003 Ford Escape. Ford also has plans in the works in which it will use the latest hybrid-electric-vehicle technologies with an advanced new fuel cell to produce the zero-emissions Ford Focus. Prototypes begin in 2004. Other manufacturers soon will have vehicles of environmentally friendly design available for purchase here as well. So it’s another technology that the auto-repair and rebuilding industry needs to prepare for.
After an overhaul during which the channel plate is replaced, a THM 4T40-E may have various stuck valves caused by mysterious metal particles.
Before and/or after rebuild of a THM 4T40-E, the vehicle illuminates the check engine lamp and stores code P1887 or P0742 in memory.
