Last month had the oil change on the transmission unfortunately the mechanic put too much oil on the transmission. I notice this problem 3 weeks later. And the car ran well the whole time. But today I notice that the car where it shows the PRNDL it does not highlight it when I put it on D drive or R reverse. And the engine light came on. I took the car to the AUTOZONE for them to put the computer on the car TROUBLE SHOOTING. And while I was driving over to AUTOZONE I notice too that it was not showing me how fast I was traveling. In AUTOZONE it game two codes #662 and #663 and the last gear is not coming on. Can you please let me know what the problem is. Thank you for your time and your assistant.

It sounds like the transmission range sensor is bad as well as the vehicle speed sensor. The range sensor will cause the lights not to indicate the gear you are in and the speed sensor will cause the trans not to shift properly and affect the speedo.
