Just pulled my 4l60 about to start rebuild. Is this normal casting marks or is this a crack??

Finally started to work on my 1992 c1500. Bought it knowing the trans was going to need work. It didn't have reverse and would only stay in low gear. Now that I'm starting to take it apart I found the TV cable had snapped off inside the hose. So I bought a new one (Napa# ATP 17909), and installed it on the hook coming out of transmission, then adjusted it. (I will note that the adjustment ratchet went all the way out and maxed out before fully WOT, had my partner press the pedal in the truck, while I depressed the D-button). Then I reattached the shifter rods and and reinstalled the drive shaft, and reconnected the two electrical connectors (2-pin and 4-pin) on the side of transmission, I wanted to test it while the truck is on jack stands so wheels can spin.

New Problem: Now It has forward in every gear even reverse, the only exception being park it actually does stop everything and hold. What happened? Also does this indicate other damage or did I do something wrong when installing the cable?

Just picked up a running decent condition ‘92 c1500 Silverado 2wd. Truck has no reverse, previous owner said they hear a loud pop/bang at the end of his street then drove it back and parked it. He said it wouldn’t shift during that time. Truck had enough power to drive its self on the trailer. Checked fluid level out when I got it home , and it was below minimum line barely on the stick (up to temperature, idling when checking. Filled it to between min and max lines.) no change. Gear shifter is sloppy at pointing at the gear it’s supposed to be in (idk if it’s a transmission issue or gmt400 issue). I’m capable of doing a rebuild, but it’s been a while since I touched a 700r4/4l60e. Just wondering if anyone had any suggestions of where to get started, or if I’m jumping to conclusions about pulling the transmission? Thanks!
