What could be causing this auto transmission problem?
I've been called upon for some transmission advice, but don't know much about diagnosing automatic transmissions...so I call up those who may know.
The vehicle is a '91 Ford Ranger with 130k miles. It was in a 5-10mph fender bender the other day. Cosmetically, the bumper got smushed in, but that's all. I drove the truck to help diagnose what seems to be something else that got knocked loose. From a stop, under normal acceleration, the tachometer works just fine, but the speedometer fluctuates up to about 30mph before it stabilizes. From 0-15mph it does not register any speed. It is hard to tell what gear the truck is in when starting from a stop (1-2 or 2-3). When in that 'mystery' range of 0-30mph, however, the transmission will make a good clunk in between gears.
They also noted the ABS light has come on since the fender bender.
Could the transmission issue be as simple as a loose speed sensor or cable? (i dont know what they have)
Could the ABS be as simple as a loose electrical connection? (once again, not familiar with abs other than it has a gizmo and some wire by the brake )
