Greetings fellow cobalt lovers.

Im pretty deep into a full engine bay rebuild. Had a piston det and gouged the sleeve. Currently searching for a standard size sleeve, but thats on the lower end of my list. My biggest issue is MU3 trans parts. I have found some on a SAAB website, but am hesitant to break down the tranny. I had issues with the shifter pooping out of 5th and other gears before she went down. As well as sometimes when shifting fast and hard, it would get stuck in a gear, but I could move the shifter around. Seemed like maybe it over pressurized because it freed up after waiting 5ish sec.

I welcome any tips and tricks, as well as info that would be benifical such as recommendations based on yalls experiences. I have decent mechanical skills and come from the heavy equipment side of maintenance and repair.
