2000 Honda Odyssey w/175.000 miles: While driving emission light came on and D4 indicator light flashed. It was hard to accelerate from a complete stop but would eventually. As I kept driving home, the ABS light, the maintenance light, the TCS light each came on. Then the spedometer, odometer, gas guage and RPM gauges bounced from on end to the other. Then the radio and navigation system shut down, then the air conditioner came on and off and then off for good. I had no turn signals or hazards. When I pulled in my driveway, the car made a choking noise and would go no further. I put it in Park and then car coughed and died. The Honda dealer first diagnosed that the alternator went out but now they called back and said it was the transmission. I have had no problems with the transmission.
