Stud on the starter side
I just finished taking out the transmission. I did it at my school, where I have access to a lift, but you can do it with a good set of jackstands and a jack or two.
The stud will come out if you put two nuts on it, tighten them to each other and then use a wrench on the nut closest to the bellhousing. It will take you like 10 minutes, lol, but you'll get it done. I then loosened the upper bellhousing-to-engine bolts slightly and supported the transmission towards the output shaft end. That gave me enough of a crack to slide the shield down from between those stupid friggin brackets that Dodge designed and the bellhousing.
Overall it's a real PITA, and I've done a bunch of transmissions in my life. This was easily the worst one I've had. Glad I'm not the one putting it back in. )))
