I am going to buy a '95 Dakota sport with 3.9 Magnum and 5 speed tranny. The speedo is not registering any speed, then it will jump up to show speed (at least I hope it is the speed I was driving). Is this a cable driven or a sensor driven speedometer, and how hard to fix? I also got a Chiltons book from the local library (general truck info for all trucks from "x" year to "y" year) and it shows three types of manual transmission (NV3500, NV4500, and the AX 15). How can I tell the difference between them?
Thanks for any help,
