Hello GMCers,
Having trouble with my Speedometer... doesn't work consistently, or for the most part, at all!
When the needle stops moving, I can temporarily get it working again by disconnecting the speedo cable from the transducer, and then connecting and tightening again. Then, it will work properly for a few miles. Later, it will start bouncing around dramatically. Finally, it will stop moving altogether soon thereafter.
I've lubed the cable properly, and this doesn't seem to fix the issue. Jim K sold me a small plastic gear that goes in the transmission, but I haven't had time to get underneath and fix it.
Are there any other reasons why my speedometer would not be functioning properly?
Your feedback is encouraged and greatly appreciated. Thank You!
Happy Holidays Everyone!
