I have a 91That was doing the same thing. There is a plug on the transmission that could be going out or its your whole transmission. the plug shorts out and causes the tranny not to know when to shift. Try the plug first. It cost about 75 to 100 at the dealer. AC delco gm # 12126437 ac delco part # PT708.

Where is the speed odometer cable at on a 19996 geo prizm?
it starts at the transmission near the firewall, runs through the firewall directly to the speedometer. you have to remove the combination meter(where the speedometer and guages are) in order to remove it.......this is not for amateurs!

The speedometer may cut off and they engine may splutter due to the Glow Plug Relay. It could also be the water temperature sensor.

How do you find speedometer cable on 1993 olds achieva?
Generally the speedometer cable starts at the transmission and ends at the instrument cluster. Visually inspect from the firewall in the area of the instrument cluster and track back to the transmission. You should be able to find it with no problems. --mark
What else can be wrong with spastic speedometer needle on a 1996 Ford Escort station wagon the speedometer cable and cluster have been replaced and the speedometer still doesnt work?
So the speed gauge in the dash and the speedometer cable have been replaced. Well, the only thing left to my knowledge would be the geared speed sensor in the transaxle. I have the same problem. Replaced the speedometer cable but to no avail. I then took the speedometer out and used an electric motor to drive it on my bench and noticed that the part that is driving the needle (driven by a magnet) starts vibrating at certain speeds. On further investigation I found that the bush on the panel that the spindle goes through ( just behind the needle) is worn and hence the spindle/shaft does not run tight and starts vibrating/rattling and then it sometimes swing up and down. When I lightly touch the needle it stabilizes for a while and then starts vibrating again. The needle is not driven directly, but through a magnetic coupling so the slightest interference can cause problems. It seems the only solution is to replace the speedometer. Unfortunately you have to replace the whole cluster. I thought I could do something about the bush, but it is too delicate and you will have to remove the little coil spring which means the speedometer will have to be re-calibrated.
Why does your Chevy Celebrity miss and do it even worse when the speedometer starts working?
That sounds like a problem within the engine control module or possibly the wiring,

Will a malfunctioning VSS result in intermittent speedometer failure on a 1999 Mercury Sable - Ford Taurus?
Yes - the vehicle speed sensor (VSS) feeds the data to the speedometer, so if it goes bad, so does the speedometer, odometer, the transmission starts acting real funky, and a myriad of other symptoms. See "Related Questions" below for more about replacing the VSS
