    Before guessing at transmission problems, check the fluid level and color (car warmed up, engine running in park on level ground) and have the PCM scanned for trouble codes FIRST. Most auto parts stores will do the scan for free. The transmission is on the same fuse as the MAF, O2 sensors and at least one other sensor - if an O2 shorts out, it will blow the fuse and the transmission will go into limp-home mode. Limp home mode will disable your overdrive. Be sure the transmission has power and the fuse is not blown before doing anything else. Next check the connection on the transmission control module to be sure it has not come loose. Now if you have no codes after your scan, you may have a bad shift solenoid A on the valve body which is a simple fix. You'll need to drop the pan to access the valve body and replace the shift solenoid.
