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.
