My car wont go into overdrive

My car drives and shifts poerfect. but it wont go into overdrive or lockup. i unplugged the trans. speed sensor and the car started shifting early and starts out in third gear unless i downshift it manually. i plugged the sensor back in, now it shifts fine except.. no overdrive. the light on the dash is working. but a while back, if the shifter wasnt exactly in a certain spot, it wouldnt go into o.d. unless i shook the gearshift back and forth a little . the light would go off and it would go into o.d. but now it doesnt.

Scan the computer for code/s, also check fluid level, and throttle and cable adjustments

Disconnect electrical connector for overdrive switch and note switch terminal identification. See Fig. 16 . Overdrive switch is mounted on driver's side of gearshift lever.
Depress overdrive switch to ON position. Using DVOM, ensure continuity exists between terminals No. 4 and 5. Depress overdrive switch to OFF position. Ensure continuity exists between terminals No. 5 and 6. Replace overdrive switch if continuity is not as specified.
