Whenever I start driving my Honda Civic 2000, I can feel a hard knock in the transmission and both the "check engine" and the d4 lights stay on. Even more, at the beginning it has lots of trouble to speed up. As code p0753 appeared, I changed the shift control solenoid but everything remained the same. I then checked the fuses under the dashboard and noticed that there was one blown fuse in position number 15. Once I change it, the lights and transmission return to normal, but after driving for a while the same fuse melts and the problem returns. Can anyone help me? Thank you in advance.
