I smelled a little bit of electrical smoke the other day & now my speedometer & odometer don't work. This appears to have caused the transmission to shift roughly too.
All the other gauges work fine. Any ideas of what could have happened?

I had a similar problem and it was the fuse for the speed sensor.
If that is not the problem, it could also be the speed sensor itself or the wiring to it. I would put it on the diagnostic machine, to get your error code and go from there.
