ok...and the transmission isnt shifting?

Customer: replied 1 year ago.
works fine on manual 1st and 2nd gear no third or D
when starting on D the transmission doesnt go out of 1st gear
Expert:  Tim's Auto Repair replied 1 year ago.

ok,,any other problems with maybe the dash lights?maybe the gear selector lights?

Customer: replied 1 year ago.
the gear selector lights works fine.
upper left side of dash doesnt have light at all
Expert:  Tim's Auto Repair replied 1 year ago.

ok,,i will give you my thoughts..

Expert:  Tim's Auto Repair replied 1 year ago.

the first thing you need to do here is to check the wire harness to the transmission and to the speed sensor,,make sure the harness isnt damaged and the plug connectors are tight and clean

Expert:  Tim's Auto Repair replied 1 year ago.

but,,your problem may be the ignition switch,,sometimes when these ignition switches go bad it kills the power to the transmission..most times it will make the dash act up,but i have seen them just kill the power to the transmission..your problem is electrical

Customer: replied 1 year ago.
thank you.
ill replace tomorrow.
hopefully it will work it out.
Expert:  Tim's Auto Repair replied 1 year ago.

be sure to check the wire harness well before buying the ignition switch

thanks

Customer: replied 1 year ago.
your answer was the same answer i got from a mechanic i went to today, i replaced it and it didn't solve the problem.
it was actually the wire that's connect to the sensor itself that was cut.
wasn't easy to find it.
Expert:  Tim's Auto Repair replied 1 year ago.

thanks
