P1870 code for 2000 Chevy Blazer LT

Question

I got a code P1870 on my 2000 Chevy Blazer and at first the check engine light was on but when I put trans fluid in it the check engine light went off. No leaks.no problems shifting fears and it drives like a champ. Whatever the issue is I feel is minor. Could it be the torque converter or valve body or could just putting the fluid in it solve the code issue?
