Check the Tourqe Converter fuse, in the fuse box under the hood.(At least that that's where it is on a 96.)
try your output speed sensor
My lexus speedoment does'nt work no running at all....I do not why it happened suddenly?
The speedometer and odometer are electrically operated. There is no mechanical connection to the drivetrain. If there is no power, they don't work.
Check wiring all along the harness. If the tranny is shifting up or down suddenly and for no reason there could be a short in the harness. 90's ford had a problem with this. May need a new harness or have to make one up yourself.
It really depends upon the type of car (year, brand, model, etc.). I had the same issue on a 90 Honda Accord. This particular car had a sending unit on the transaxle (transmission) that failed. The connection from the sending unit to the speedometer is electrical. I replaced the sending unit and all was well. Other cars have a cable that connects from the transmission to the speedometer. If you have this type of car, the problem could be the cable, the gear at the end of the cable that runs off of the transmission or the speedometer itself. More information is needed to provide further details. What type of car do you have? Do you have a manual?
Check conections located aft of dash. Check fuse block. If you can'y find it sale it. ;)
It sounds like the main switch is malfunctioning and it should be replaced.
check the fuses. Same thing with my 96 corsica, along with a few other instruments.
I just had this problem and had to replace the torque converter. Also the two three solenoid was bad..
Your computers sound system may need replaced.
There is still a small chance you could conceive when taking birth control correctly and accuretly. Because of this, I would do a pregnancy test.
