My stupid speedometer is still actiing up. i have a guy coming to look at my 1997, and I dont want it jumping around. I want it fixed.

I changed out the rear speed sensor on the differential, and it is still jumping around. In the past, I have pulled the plug in the side of the tranny and cleaned it. This has helped for a short period of time. I want it fixed permanantly.

Any ideas? I guess I will just pull the plug and clean it.

 

My 97 did the same thing and although this is not the quick fix, the permanent fix was to replace the speedo. I bought one from a slavage and adjusted the miles on it to match the original and it has worked perfectly since.

 

The actual speedometer inthe dash, or the plugin the side of the tranny?

 

The actual speedo in the dash. It cost me about $125 and i had to buy the whole instrument cluster to get the speedometer.

 

Does your speedo stay at 0 mph until you get to 35mph or so than it jumps up? My dakota did that and the dealer changed the rear output speed sensor and fixed it. I believe that they can't be cleaned and must be replaced. I tried cleaning the output sensor sensor on my tranny on the dakota when that went bad and I was getting poor shifting and a check engine light. I then got a new sensor from the dealer and replaced it myself and it took care of that.

 

it is a 2wd. 5speed. I changed out the rear speed sensor. I cured the Cruise COntrol and ABS, BRake lights staying on.

I had a guy come look at it, and he wants to buy it. Eventhough the speedo is not working properly. He asked if I could fix it, and I told him I would try.

I was honest about everything, and I think he respected that.

 

When mine acted up I the sensor off the back of the tranny and thouroughly cleaned it and the hole it came from. It hasnt acted up since. Appenertly the thing had some oil on it and after I cleaned it everything was good .
