03 impala 3.4 please tell me exactly where the neutral safety switches what I put the other transmission in I didn't even think to check about the safety switch I should replace it

neutral safety switches are for older vehicles, your impala has an IMS (internal mode switch) which is inside the transmission

I think you ay be describing a broken shift cable. What have you inspected so far? Will you be repairing this yourself or just inquiring? This would be easier with two people. Set the E-brake, chock at least two wheels, key in run position but engine Not Running. one person underneath looking at the neutral safety switch and the other moving the gear selector through the gear selection range. If the actuating arm coming through the neutral safety switch does not move while the different gears are selected. Then likely the cable is broken at either end.

Doesn't have neutral safety switch , has internal mode switch . Location inside the transmission

The reverse lights are operated/controlled by the neutral safety switch located on the transmission close to the tranny dipstick. This switch is adjustable and may correct your problem with a slight adjustment. Here is a picture that may help.

I don't have the diagram, but will tell you , these lights are controlled by the transmission neutral safety/ range sensor switch. Depending on you transmission. the switch is inside or outside of the transmission. The one on the outside you can replace, about $50. The one on the inside You don't want to touch, unless you're comfortable rebuilding transmissions. At a shop will be about $600 to fix.

sounds like the park solenoid needs replaced. It is hard to get to & you may ask a friend to video tape you as you replace the part, also you may have a neutral safety switch going or gone bad. Look under the car to see if any obstruction at the transmission.

The neutral safety switch is located on the side of the transmission and it is usually attached behind the shifter linkage and it is secured with two small bolts that can be loosened up to allow for adjustment of the neutral safety switch.

To adjust the neutral safety switch place the transmission into neutral, (block the tires) there is a notch or and indent marker on the housing of the neutral safety switch that should be lined up with a line on the face of the collar that is around the shifter detent shaft, and if they are not in alignment then loosen the two bolts that secure the neutral safety switch and then turn the neutral safety switch until they are aligned and then tighten the securing bolts to the neutral safety switch, and then test the starter. If the starter fails to engage then either the neutral safety switch is faulty, the neutral safety switch has been by-passed all this time and the by-pass (I will usually find things like a paper clip shoved into the vehicles wire connector with electrical tape around it) has fallen out of the wire connector from the vehicle wiring harness, or the battery just went dead. if you have the neutral safety switch from the old transmission still available try using it to test the neutral safety circuit. I have provided you with an image to help assist you adjust the neutral safety switch.

possible but it can also be a range selecter switch problem. any work done on vehicle lately? pleas respone and i will try my best to help thanks.

NO it does not even click, I turn the key, the lights come on and the fuel pump engages, but no other sound, even before I replaced starter. No the reverse lights do not come on
