Im pretty new to the car world still. I know a little more than the basics but not much. do you think a transmission for $250 with 100k on it is worth it? My trannt is stuck in third but the shifter moves by hand. any suggestions?
Sounds like your 3/4 shift fork may have broken. If - with engine OFF, or course, or you'll grenade the box completely - you can shift into 1/2 and 5, but 3/4 feels funny, that's more evidence to broken fork. Of course, you'll never know for sure until you take it all apart.
$250 seems like ok-ish price for 100k box. Not great, but not terrible either.
If your old box was in good shape otherwise, and you have a neighbor that's willing to help you with a rebuild, might be worth a try to repair it. If it had other issues and a million miles, forget it and get another box, cause a full rebuild is more money than it's worth.
