Most likely causes is the OD shift solenoid or less likely the VSS

Where is the neutral saftey switch located

For 2003 Buick Century 3.1L SFI OHV 6cyl NSS (Neutral Safet Switch) it will be mounted on the transmission shifting stud and lever, where the cables connect to the rod that runs down into the transmission (is a black box with a plug on the side).

Hope helps.

What is the o/d button on top of automatic gear stick for please

Over Drive..... Generally speaking, overdrive (OD) is the highest gear in the transmission. Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway. When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [43+ mph] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. For an automatic transmission, it is almost always best to select overdrive and allow the transmission to control engagement of the overdrive. (It may be necessary to switch it off if the vehicle is being operated in a mountainous area or when towing a trailer.) With a manual transmission, overdrive should usually be selected when the average speed is above 70 km/h (approx. 43 mph).

I need the location of a neutral safety switch on a 1999 buick century 3.1L.

I take it that you have an automatic transmission the shift selector /neutral saftey switch switch is located on top of the transmission were the shift cable connects to the trans. Remove the 13 mm nut in the center of the switch and remover the shift cable and lever noting the location of the lever. then remove the bolts holsing the switch to the transmission and the elec connector.

Cold Start and TRanny issues.

A neutral park switch keeps you from activating the starter in drive or reverse. It also turns the reverse lights on. Its on top of the transmission at the end of the shift cable . If it does not turn over in park try it in neutral, Clean battery cables. Check fuel pressure. Is check engine light on?

Transmission problem on 95 cutlass ciera

Overdrive has two important factors involving when and if it turns on besides being in the proper gear shift position. One is tthe car has to FIRST reach operating temps before it will engage the TCC ( torque converter clutch ). That could involve a faulty thermostat, or short distance drives, Second important factor WILL DISENGAGE WHEN STEPPING ON THE BRAKE PEDAL. A brake switch could be misadjusted , and without you stepping on the brake, the computer thinks you are and wont engage TCC. Hope this helps.

Won't shift into overdrive

The engine temp has nothing to do with overdrive, transmission temp may, but either way if you are just coasting it should go in, or maintaining a speed of at least 44mph it should go in. How many miles on your car? It could be a sign of worse to come, usually the highest gears go first.... 3rd or 4th gear could be next.
