Got it back from the shop, total damage was about $1200 for a used transmission, installation, new U-joints, and a new clutch.

I didn't realize but this sportage has had bad u-joints since I bought it. There was excess play in the driveline which you could feel when switching from accelerating to decelerating, or sometimes when changing gears.

You may wonder why I didn't know this was a problem. Well, I thought all Sportages had sloppy drivelines like that, because before this I had another Sportage, and it was the same way. BOTH must have had worn U-joints but the joints on the first Sportage never started to vibrate.

Lesson learned, it was about a $1100 lesson... At least I paid only half what the first shop quoted me, and that quote did not include new clutch.
