I just put in new fuses in everything today and when I took off down the road, I was listening to the radio and when it went from (D) to (OD) the fuse for the radio popped, this was a 30amp fuse! I changed the fuse and went down the road again, and it did it again when shifting to OD. So I changed it again and keep the selector in D and everything was fine.... So my question is why is this doing this only in OverDrive? Trans is a 700R4, I looked for disconnected wires and found none, is there something wrong with my electrical system or is the truck surging while it shifts, either way this is not good, I have to have my radio. * if anyone can help me out on this I would appreciate it.
