Speedometer malfunctioning Needle just jumps back and forth. Odometer works fine. Gas gauge also doesn't work.

check the connection from speedometer to transaxle. Often this becomes loose, especially the transaxle side. Also 92 was a first year model and have heard many wacky problems.

Sounds like either your speedometer cable, your nylon gear on the side of the tranny where the cable ties in, or the odometer itself is shot. One of those three will set you straight. If you are able, remove the cluster, take the cable off the back, and pull it out of the sheath. You will see if its broken or not from there. If not, slide it back into the sheath, then you have to find out where the sheath meets the tranny, and pull it off of there. Then, you can get someone else to watch the speedo as you turn the cable from the bottom. If it works, great, if not, then its your cluster/odometer/speedo. If it does work, the small gear in the transmission is shot.

check your speedo cable it runs from your transmission to the back of your gauge cluster. its probleby broken or disconnected

SOURCE: Car speedo & odometer sometimes work OK, other times not at all.

Most likely a speed sensor is going bad (most cars and truck do not use mechanical speedometer cables anymore) most sensors are located near the differential in rwd cars or near the drive shaft on the transmission. Best bet is to get a Haynes manual for your car to help locate the speed sensor. Remove it and take it to the auto parts store so you can visually compare it to the replacement. Install the new speed sensor and it should restore your speedometer and odometer.

the only thing that is related is the d4/rough gear changing
speed/ rpm malfunction is caused by your speed sensor on the trani (common problem) change it
