Here are what the codes mean: PO1698 - No messages received from the electronic transmission control module or the Aisin transmission controller.
PO601 - Internal computer error!
PO500 - Haven't heard from the speed sensor lately.
I would start by having the vehicle speed sensor replaced. It is much cheaper than the control module and chances are it is the problem.
Let me know what you find.

Are you getting any codes?

No codes. Could it be a fuse under the hood?

I have a pt cruiser automatic and the car sometimes wont shift from first gear. Sometimes if I turn it off and start it back it will shift. I have codes p0882 tcm low voltage.P0218 transmission fluid overheating. P0714 transmission sensor intermittent failure. P01603 pcm ram failure. U0101 tcm no communication and p0562 system low voltage.I took the car to autozone napa and oreilly to check battery alternator and starter tgey passed so I do not know why that code p0562 is there.
