My dad was emotionally absent and I'm terrified I'm doing the same thing

I grew up barely talking to my dad about feelings or anything real. He was just... there but not really present. Now I have three boys and sometimes I catch myself being exactly like him—physically present but mentally checked out, not asking about their day, just going through motions. It scares me. I'm trying to be different but I don't even know where to start because I don't have a model for what good parenting looks like. Is this something therapy could actually help with or am I too far gone?
