Speed odometer and tach erratic then vahicle cuts off

Most likely an internal cluster problem. These units are printed circuit boards and anything from solder to a loose transistor can cause problems. The guage assembly will have to be removed and tested/repaired to correct the problem

Not familiar with this model, but suspect crankshaft sensor when tach is erratic.

i believe it has a vehicle speed sensor in the rear diff that is probably your problem as the sensor you replaced in the transmission was probably the output shaft speed sensor

tach not working

It sounds as if the vehicle speed sensor is malfunctioning.

Hi,

I had a similar issue but the issue is not related to connections. There are many steps involved with this, but it is related to two transiters on the circuit board that have overheated the connection for the odometer and the tachometer. To complete this job, I did it with a $17 soder gun and $3 worth of tin solder.

Anyways, I got it to work after this.

You need to unplug the battery, take off the radio panel, the dash, unscrew the speedometer casing from being held on, take off the back, unscrew about 15 screws, unplug the gauges from the computer, then take out the circuit board. There should be two blue transitters very close together and between them, a small nub that has likely worn away. Also on the other side of the board, a browned spot likely exists. Each of the transitters will need new solder.

This link that I followed will fix the issue.

the tach is electric .it could be the tach itself or the pick up in your dist

Yes your speedometer, and odometer are controlled by your speed sensor.

replace the speed tranducer, located on the gearbox
