2003 chevy silverado will not shift into drive or overdrive.

The transmission shifts fine except it will not go into overdrive and stays in 3rd gear all the time. Maybe overdrive switch?

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

Check your input or output speed sensor, One of them may have gone bad. If your spedometer works than its your output speed sensor. Another thing to check is TCM or ECM. Sometimes even ground wires aren't grounded anymore and can wreak havoc on the BCM, TCM or ECM. I would check on all these and relays as well.

2003 ford focus... possible transmission problem.. or electrical?

Overdrive is a lock up within the transmission. The other "gears" are fluid and belt driven. So, could be that the sensor that allows the overdrive to "lock" is dirty/faulty. A transmission shop should be able to tell you in a heart beat.

99 silverado will not shift into overdrive

have a 1998 K3500 silverado 4x4 with 454 motor and 4L80E transmission. I can not get over 55 or 60 mph. At that speed the transmission down shifts from 4th (OD) to 3rd. The speedometer also drifts from about 50 to 65. If I try to speed up it will down shift to 3rd. I have replaced the VSS on the trasfer case. Is there another speed sensor somewhere? Or could it be the TPS? The truck drives and shift normal up to this point. where should i look next. thanks
