Backhoe Transmission Will Not Engage NH 555E Backhoe

[EddieWalker]

The cable that controls forward and backwards, on the side of the steering column might go out. It's been awhile, but I replaced mine for some reason that I can't remember. It wasn't too hard, but I can't remember what it was doing when I replaced it.

My current repair is a new cable to one of my outriggers. It goes up, but it doesn't want to go down.

I have to ask the stupid question, did you check your fuses?

 

[EddieWalker]

Back in 1998 they didn't have a lot of safety features or electronics. I can't think of a fuse that would affect it being able to drive. It's all mechanical.

On the contrary, the C Series in 1988 had a simple transmission computer.
The E series was introduced in 1996 and the transmission is more computer controlled.

I haven't seen that on mine. Where would that be on a 555E?

 

[EddieWalker]

I just looked at the electrical diagrams at Messicks to see where the computer is, and I can't find one. Are you sure there's a computer on them?

Here are the transmission harness and F/R solenoids

I saw those diagrams, but didn't realize they where computers.

I misspoke, this transmission is not computer controlled, but is completely electrically controlled. Fuse F4/A would be a place to start

@audieo, this thread got long. I just went back to the beginning and saw that you checked the fuse. Being the harness has been riddled by rodents. I would next check the dump circuit coming from the range shifter and the loader lever for a short that is energizing the transmission dump solenoid.

Another question, does the steering and stabilizers work?
