Odometer repair

Ace23 · #1 (**permalink**) 05-04-2016, 10:44 PM

My speedo has 13,000 on it and the only issue I have is the speedometer floats almost like it's in a liquid gauge. I think this may be related to the speedo cable having a kink in it or not being ran the best position. I also check my mileage and reset my odmeter at every flll up. I've noticed that my odometer also turns a little more mileage than it suppose to. My car had a gear swap to 3:31's or 3"27's and I bet they didn't make the speedo gear change. Just a few more of the small things I will be correcting over the summer. DWRAT what do you think?

My speedo also floats around at low speeds, nothing to do with the cable I bet.
You can change the speedo drive gear in your transmission to get a more accurate reading.

You can use a GPS to check the odometer on longer trip. I checked the B&B last summer on the return trip from the London Cobra Show and found it was 1/2% off. Changed the trannie gear and now it "almost" perfect.

I use an app on my cell to check speedometers.

My speedometer floats between 5-10mph plus or minus whatever speed you are going.....it is just one of those things that annoys me. I will look into replacing the speedo unit If I can't get it to act right. I'm going to go with the cable and the speedo gear in the transmission first.
