Abs light is on, break light flashes on and
off speedometer jumps around and causes
the trans to shift down. What could cause

1 Answer


Failure in the antilock braking system for the ABS light, an ABS code will be needed to find out what is going on with it, could be a bad wheel sensor. Inside brake warning light could be just low brake fluid or a park brake cable adjustment needs to be made, as you related the speedo with a trans shift problem that sounds like a transmission speed sensor erratic output.
