Hey everyone, first post here (somewhat thankfully, somewhat not lol). I have a 2006 Pontiac Vibe base 5 speed with around 298k on the clock. Didn't check the exact mileage earlier. I'm looking to source some info as I'm not a transmission guy at all.
Today while driving the car it started making a whining noise (sounded like gear whine) and when I slowed down to turn into my driveway the car made a loud "clunk" that could be felt. I pulled up the driveway and backed into my parking spot to check it out, and upon pulling the e-brake I went to put the car in first and shut it off. This is when I noticed the car will no longer go in 1st or 2nd. 3rd-5th and reverse have no issues whatsoever. Does anyone have any ideas as to what this could be? I'm hoping against hope it isn't the synchros, because I've grown attached to the car and don't want to replace it right now but it also isn't worth it to me to replace or rebuild the transmission for what that costs. If anyone has any suggestions it'd be very greatly appreciated!
