Computer controlled transmissions can get confused at times, from my personal experience. If the problem doesn't happen again, I would ignore it. If it happens all the time, it's most likely the transmission computer. Other things could be the shift linkage, engine vacuum leak, speed sensor, etc... Hope this helps.

Why my 2001 Honda civic will not shift into overdrive even going 40 miles an hour?


There are adjustments to be made on the outside linkage of your transmission. Take it to an honest transmission shop that won't tell you to replace the whole transmission.

check the tps ( throttle position sensor ). a bad tps causes transmission shift issues, bucking, jerking, idle surging, engine cutoff, hesitation on take off, surge while cruising down highway. am not saying this does the trick, but it is a good starting point. good-day !

Sounds like it's bypassing the overdrive seals. This is the solenoid package. I would put some transmission additive in first, this reconditions the seals. TranX, Lucus are both good.

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).

2003 chevy silverado will not shift into drive or overdrive.


transmission shift solenoid is stuck open this is a common vehicle issue in automatics and not particular to any make or model vehicle 15 dollar part and arm and leg for labor if taken in

heres an idea to try
take out the transmission filter and replace with new one make sure to take not of any metal debry in trans pan this indicates the trans had sheered its gears down and a trans rebuild is needed
the transfilter needs to be changed at a certain milage interval they can get clogged up
there is a kit you buy for your truck at any parts store
its an easy change hour of time unbolt trans pan unbolt trans filter and put new one in
kit comes with new seals less than an hour you can do it yourself

to overdrive you would feel a difference in shift badley if it was that something to keep in mind

The service light is a reminder for you to have the car serviced, it can be reset, and it will come on again in 5,000 miles or so.

The overdrive light may be caused by the wiring to the overdrive solenoid on the transmission, or the relay. Just be sure the wiring is ok before replacing the relay, or you can damage the new relay.
