abs light on as well? even tho you changed the speed sensor did you clean the contacts really well? i had the same problem i replaced the sensor and nothing.... then found out the contacts were corroded took the sensor back off and cleaned the contacts. works like a charm! try that and let us know if that helps.

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

Hi, this is a defective OD shift solenoid that is located inside the trans pan. you will have to drop this pan in order to extract it for replacement. this solenoid, if damaged, cant initiate the shift sequence required for the OD to engage during operational procedures.
Simply replacing this solenoid will fix this issue.
NOw, concerning the erratic shifts. this is isolated within the transmission control module. it seems to be malfunctioning. you will need to replace this module as well.
