kneebuster

I have a 2000 Accord that shows a P0740 code, TCC not working or a poor conection and a P1164 code, a Ho2s (I don't know what this is). There is also a P0700 code, which I believe refers to the P0740. The only driving problem I've noticed is the trans sometimes seems to hunt when accelerating from a rolling stop. I restore old cars, but this new stuff is foreign to me. If anybody can point me the right direction and also help me locate the items to be checked, it would be a great help. Thanks
