I have been having some tranny issues recently specifically P1870 code, I have seen before that could be a TCC issue. Is there anyway to remove the EPC and wiring harness with the trans still connected. I have no way to disconnect the trans if I did I would of just replaced the valve body too. I purchased this kit in the hopes that the combo of new solenoids would fix my problem.

Any help would be greatly appreciated

edit: It is a 4L60E
