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

front clutches bad needs to be rebuilt

SOURCE: Code Reader reads Shifter Solenoid Stuck or Off

The Shift solenoids are located in the transmission oil pan. I would recommend replacing both shift solenoids while you're in there. Also replace the filter and pan gasket. The shift solenoids are located towards the rear of the valvebody and will be identical to each other. They are held in place by a retaining clip which is easily removed with a small screwdriver or similar tool. Care must be taken as parts may fly out of the bore when the solenoids are removed. Hope this helps.

SOURCE: chevy transmission hangs in 2nd,

It just holds 2nd forever. Is the 1-2 shift point high?

SOURCE: 1997 Chevy 1500 P/U 4x4 small V8. Transmission shifting issue.

you may be confusing the torque converter clutch engagement with o.d. this trans has a problem with the T.C.C. regulator valve wearing out the valve body bore. this will cause the converter clutch to engage only sometimes or not at all. this will set a P1870 code in the control module. when this code is stored in the controller, ( check engine light may or may not be on), it increases the pressure in the transmission causing the 1-2 shift to be harsh. ask a local tranny shop to scan the vehicle ( most will do this for free) if this is the problem they can either fix your valve body (sonnax parts) or replace it with an upgraded valve body. hope this helps
