El Chapo Posted November 12, 2022 Share Posted November 12, 2022 Installed new speedometer cable and driven gear, speedometer radically moves jumps around and unstable also appears to read a much higher mph then actual speed by like 15 mph. What could be the causes for this. Does anyone have a working one for sale 4 speed automatic with tachometer. Link to comment Share on other sites More sharing options...
Gary Lewis Posted November 12, 2022 Share Posted November 12, 2022 Did you lube the speedo cable? I bought a new one that said it was lubed, but it really wasn't and the speedo was jumping badly. I pulled the cable and sprayed it with Teflon and also graphite. That helped a bunch but it was still jumpy, so I lubed it with synthetic wheel bearing grease. Thick and sticky stuff. And it tamed most of the jumps. Link to comment Share on other sites More sharing options...
El Chapo Posted November 12, 2022 Author Share Posted November 12, 2022 Thank you Gary that makes sense and I now remember that Mat also mentioned the need for that in one of my previous posts. Peace! Link to comment Share on other sites More sharing options...

You can get a cable luber to aid in fully lubing your cable too! https://www.amazon.com/Motion-Pro-08-0182-Cable-Luber/dp/B0012TYX9W/ref=sr_1_4?crid=3UW0ZMD9WYE8B&keywords=cable+lube+tool&qid=1668344425&sprefix=Cable+lu%2Caps%2C114&sr=8-4 Link to comment Share on other sites More sharing options...
