C6 adjustment 1st gear

I have a C6 behind a 390, trans has about 3000 miles on rebuild, I notice when left in drive or 2nd & I come to a stop when I start off again it's stuck in 2nd gear and pulls hard, I can manually shift to first & feel it down shift as I'm pulling away from a stop,is there a way to adjust this?

With the shifter in 2 the trans is designed to stay in 2, not shift 1-2. So there is no adjustment for that. If it is in drive and not shifting to 1st gear I'd suspect a sticky shift valve in the valve body.

I didn't know that about the second gear, thanks for the info, what are your thoughts on what torque converter to use, right now I have a 1300 stall installed.

You want to have a stall speed that is slightly below max torque RPM for best performance. You want to be quite a bit below that for best fuel economy.
