Answers :

P0720 almost always points to a problem with the output speed sensor itself. The sensor is located on the top of the transmission near the rear. It's held in place with one 10mm bolt. You may be able to access with a long extension and a 10mm swivel-socket. If not, you'll need to remove the air box. You'll find the sensor semi-hiding under the wiring harness that runs across the rear portion of the top of the transmission.

P1529 is simply an indicator that the transmission control module (TCM) requested the engine control module (ECM) to turn on the check engine lamp.
Let me know if this helps or if you need mor help.
