Q: Car won't go in gear when hot?

Hi there, thanks for writing in. I'd be happy to help. Your transmission is a computer-controlled transmission which can be affected even when something as simple as a weak battery is the issue. I would first suggest checking the battery to be sure it is not weak. Secondly, I would recommend checking the transmission fluid to be sure it is at the correct level. Lastly, I would recommend having an expert from YourMechanic come to your home to run a scan on the transmission ECU in order to pinpoint the issue.
