2000 LS/VTEC

Hello everyone. My Transmission is really acting up one me. I want to know if any has ever done a H22A swap with a manual into their 1999 Accord V6 Automatic. I'm really wanting to this swap sometimes soon. I've seen people put H22a into 1999 accord that have the four cylinder and 5 speed already. So i was wondering if it is possible to do the same in my car? Please let me know. Any info will sure help
