It sounds like the transmission is going bad but I would try to replace the engine coolant temperature sensor which could be shorting out when warm causing the issue.

Here is a guide to walk you through the steps and diagrams below to show you how on your car:

Check out the diagrams (below). Please let us know what you find.
