SOURCE: 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

CAR GOES INTO DRIVE BUT DOES NOT SHIFT OUT. WILL NOT EXCEED 35 MPH

Unscrew the wing nut on your air breather and lift it off. On the driver side of the car, on the side of the throttle body there is a bar/linkage that comes up from the side of the transmission that is supposed to be connected to the throttle body by a small plastic bushing/grommet fastener. As they age, they break off and will cause this delayed shifting. If you drive it hard enough it will eventually shift (35-40 mph) out of first gear. Probably wont shift out of second until closer to 65-70 mph. Same thing happened to me. I thought geeze this thing is not going to shift but it will. Should be a simple fix.

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

Driving 65 MPH and engine rpm goes to 7K. Not in O.D. light comes

sound to me like it maybe a faulty sensor in the transmission. take your car to someone with an ODB reader and see if a transmission fault is indicated. you may have to take your car to a transmission shop.

Shifting problems

The transmission/computer is designed not to go into overdrive until it reaches a certain temp and I don't remember what the temp is. Mine does same thing and it has 250,000 miles on it. When you start your truck up do you start it and warm up in neutral? The transmission fluid won't flow unless it is. There is know way to force it to shift into overdrive until it warms to the set temp.

Hope this helps
