Have you tried replacing the neutral switch, go to autozone, they run around $5 and easy to replace
If you have an automatic transmission it is on top of he steering column just before it goes through the firewall. If you have a manual transmission it is on the transmission.
You didn't state weather it was an Automatic or Manual transmission. Well any way they are both on the transmission. Manual transmission has a separate switch for the backup lights the automatic is built into the neutral safety switch on the transmission. Automatic switch is about $50.00. Manual switch is about $10.00. Hope you have a manual it is a lot cheaper.
There is no relay for the backup lights. The circuit is powered by the keyswitch, runs thru a 10 amp fuse on the interior fuse block, then goes through a switch mounted on the transmission, and on to the lights. The switch is on the front of the manual transmission, and on the lower front of the automatic.
I dont think manual transmission cars use transmission fluid.
screwed into the transmission.
There is a switch in the transmission (manual) and I believe also automatic that triggers your backup lights when you move (change gears) into reverse. If the switch (in the transmission) does not touch (trigger) the backup light switch; or if the switch is not working; you will not have any reverse lights. Also , if you have had any changes in your transmission due to lifting the body, or changing the original transmission; the lever that triggers the switch may not be able to come in contact with the backup light switch in the transmission. If you have this switch replaced by a garage it may run around $160 for the switch and another $100 to $200 for labor. If the transmission does not trigger the backup light switch in the first place ,due to changes in the transmission, or a body lift; then changing the switch will not make any difference; the backup lights still will not work.
on the side of the transmission
YES BOLT ON .THEY ARE THE SAME 1992 TO 2002 FOR A MANUAL
Dexron II
