The car was driving really well when out of nowhere the transmission went out and would only engage over 4000 rpms. After making it home averaging 8 mph, tried to replace the throttle body control sensor, draining the battery and capacitors, and allowing the PCM to relearn where to shift. According to YouTube, this was the problem, but the transmission still won't engage into drive, 1 or 2. It will, however, go in reverse. The engine runs great and car is in great shape, but it won't drive.
