If you open the odometer, there are two small plastic gears. One is connected to the speedometer, the other to the odometer. The speedometer gear drives the odometer gear. In all likelihood, one of these gears is missing a few teeth. I have the same problem with my Ramcharger, same year.
If the gears are clunking in the transmission, this is a transmission problem in a 1998 Dodge Grand Caravan. The fact that the speedometer went up and back down suggests that the transmission slipped. It is more likely that a gear belt in the transmission failed, than something being wrong with the transfer case module or TCM.
It could, vehicle speed is very important in shift scheduals

Speedometer is ran by electronic sensor on rear end. Odometer is ran from speedometer. If both don't work problem is sensor. If speedometer works sensor is okay. If speedometer works and odometer does not problem is in mechanical parts (gears) of of odometer and has to be replaced. Can get used from eBay (search for speedometer or odometer, is one unit) or take to dealer.
Have you ever had the linkage adjusted? 90% chance this is the problem.
If speedometer itself is working then gears inside the assembly are damaged.
Have had this on my toyota. Internally on the speedometer there are a set of gears that are lubricated with grease. They dry out over time and loose the lubrication causing a click. Mine was time consuming t get out but easy enough to do. I gained access to the gears thru a hole and sprayed in a teflon lube. FIxed the problem nicely. Jonathon
The gears in the speedometer are stripped. If the odometer is working then you have input.
There are different sized gears that install in the transmission to fix your problem. Follow the speedometer cable down to the transmission. Unscrew it. There will be one bolt that holds the gear in place. Remove it and take out the entire unit. Different gears are different colors. You'll probably have to experiment to figure out which one you need. Some parts stores and most dealers carry these gears.
when you get bigger tires, or different rear end gears.
check your alternator it might be bad.
no it has 6 gears
check transmission fluid then go to transmission mechanic. problem may be in computer and be a simple fix
The speedometer in a car runs based off the speed of the transmission. The gears in the transmission spin at a known rate for the speed the vehicle is traveling at. The faster the gears spin the more the speedometer goes up. If a person replaces stock tires with larger tires, then the tires will spin slower, which will cause the speedometer to read at a value that is less than the actual speed.
If the odometer is not working but the speedometer is still indicating speed, the most likely fault is a set of small plastic gears inside the speedometer instrument itself. I have seen these gears available for sale at various BMW parts specialists. Removing the dash cluster for access to the speedometer is not difficult in a 1987 E30 car. With the cluster on the bench, you can repair the speedometer gears or replace the whole thing. Used speedometers are plentiful at on-line auction sites such as eBay.
he doesnt die
The early 700R4 transmissions had a cable drive speedo. Maybe you can swap the tail housing and gears over.
Probably a valve timing problem. Check your timing gears and chain/belt.
sounds like the speed sensor. it sends a signal to both the speedometer and the transmission
changing the gears in a rear will mess up your speedometer. you need to reset the computer through a hypertech power programmer or some equivalent programmer.
Speed sensor on Trans, or buffer behind dash... OR, any broken wires in this circuit. Very common problem on this and many other vehicles.
Automatic Dodge Neons had a 3-speed automatic transmission.
you could get 2.92, 3.23, and 3.55, and 3.90 gears in the darts
