I put a new transmission in my truck, and it never ran the same rough and doesn't have throttle response and then it just shut down while driving at about 20 miles an hour and #22 maxi fuses was blown, and it keeps blowing same will not start.

Hi,

I pulled up the power distribution wiring schematics to see what could be causing the issue. The only fuse 22 I could find was a 10-amp fuse after the accessory delay relay in the central junction box. See pic below.

Can you reconfirm that this is the correct number and which fuse box you are finding it in?

Let me know.

Take care,

Joe

Thank you for your quick response. Joe, the fuse that I am looking at is under the hood on the driver's side and it has my relays and the whole bank of smaller fuses, and you did say a 30 amp. I'm looking at a diagram that I downloaded Ford's not very good with their fuse identification chart my box has no identification on it for the purpose of the individual fuses and just tells you what amp it is so I could possibly be looking at the wrong one the one that you sent me I don't even know where that's at that has nothing familiar with me that even looks like anything that I'm looking at I'm looking at the big box that's under the hood on the driver side and there's a bank of smaller fuses and then there's the big ones and then there's all my relays right there and there's about three boxes but the one that I'm looking at his number and it was a 30 amp and I didn't replace any of the fuses before I drove the thing I haven't owned it that long but I didn't go through any of the fuses and replace any of them so it wasn't something that I had to replace you know and mistakenly put the wrong size in because it ran until the tranny got replaced and then it just ran rough and not the same and it eventually blew that fuse and then it just quit on me on the diagram I'm looking at number 22 it says is the junction box fuse relay panel ACC delay relay and it's located right next to the relay that says wfw run and Park and this I got off of motoguruma. Sorry for the lack of information I just am not real car savvy and I had somebody else working on it and apparently every time he came he did something different underneath the dash apart and the muffler off of it and all kinds of stuff said maybe a Cadillac converter he never put anything back and now has become a ghost so when you help I can get is greatly appreciated and I'm about as good with computers as I am with car so bear with me if you have the time or the patient anyway let me know what else you need and I'll try my best to figure it out so you can help me I will help you help me thank you very much.

Hi,

I'm still not sure which fuse you are referring to. Do me a favor. I attached the power distribution schematics below. Take a look through them and let me know if you spot it.

Let me know.

See pics below. Note: I had to cut each page in half to make them readable. I did overlap them so you can follow from one to the next.
