PO720 code

99 Dakota 5.2 4 wh drive

Have this code. Changed output speed sensor on the tranny and the rear differential.

After resetting the check engine light comes back on just after 15 miles an hour.

Any suggestions ??

The rear sensor is for the ABS and the other is for the transmission. If you have P0720, thats for the trans.
