this might be something to do with the VSS or another tranny problem. there is a plug on under the glove box on the passenger , side if you put a paperclip in there and turn the ignition to accessory the check engine light well blink , one long blink = 10 , and short blinks = 1 , after its done add them up and there is your code.

I just dealt with this problem. Your TCU is probably fried. Mine was. Take it out and look at the bottom right corner of it. You'll probably see some leaking capacitors and a fried resistor or two.

Or you could reset your ecu by disconnecting the negative cable from the battery for about 10 15 seconds and then connect it again

Did your check engine light come on? If not, then the problem is in the tranny/TCU, like mndude said. Just going on what you said above, it sounds like the TCU to me, too.
