Won't… Won't shift.

You have a transmission problem. If you are not handy you will need a mechanic.Blinking light always means major problem, or one that is fixing to be.

Light on means code. Will have to find out what that code is. But if fluid smells burnt good bet the transmission needs to be rebuilt. Find local shop at ATRA.COM for more help
