Automatic Transmission... everything seems to function fine, except the tach... It will idle at 2k and then jump to 7k (motor of course doesnt rev that high, just the needle moving) and then down to 5k for example... Up down, up down... I can drive down the road and then all of the sudden have the tach shoot up. I'll tap the dashboard and the tach will drop down... Thoughts on fixes? Regular occurrence?
