Yesterday my check engine light came on but I was driving 100 miles back home so there was nothing I could do unless I wanted to spend a bagillion dollars on towing. So I drove it home but about halfway there I noticed my 4th gear kept getting stuck. It feels like when you don’t hit the clutch yet and you try moving the gear, but even when I hit the clutch the only time it shifts down to 3rd is if I’m bellow 1k rpm. I’ve been looking all over the internet trying to diagnose what could’ve happened and so far my best guess is a faulty solenoid. If anyone’s got any suggestions as to what I could do that’d be very helpful ! I’m not trying to take this in to a mechanic unless I desperately have to.
