I have a 2001.5 Civic EX Coupe AT and my tranny just died out too. I don't know exactly what the problem is. First I think the car lost 1st. Instead of shifting into drive I would have to shift 2nd and the 3D and then D. Then one evening it just died out.
It also makes a bit of a whinning noise.
OBD reader says "Manufacture Transmission Control"
Any ideas?
