Rancher AT - Won't Shift Out of First Gear

56591 Views 30 Replies 9 Participants Last post by  oCancerPatiento
2005 TRX400FA Won't shift out of first gear. When in Drive the dash display reads out "- -" instead of "D". Any ideas or thoughts are welcome.
This is my second post on this problem. After 84 views & no responses I can only assume that I need to see my dealer to have this problem diagnosed?
I need some experienced advice, please help.
Thank you.

I would be interested to see if the new ECM fixed your problem. I have a similar mis-behaving 2004 Honda Fourtrax 400FA, which started off with code6. That was the angle sensor. After that, I got code 12. All along, I only had limp mode 1 speed forward, and hesitant reverse. I verified continuity, replaced the shift control motor, ECM, battery, and I still had the problem. I then determined the voltage rectifier was pooched, and was providing excessive voltage. I replaced that with new, and got ANOTHER ECM. Still no dice.

I then started thinking along the lines you are. Why won't this POS find Neutral? There are 3 little plugs on the left lower side of the engine, just inside the plastic cover. They have the labels D/N/R indicating drive/neutral/reverse. I found that one plug (reverse) was severed. I fixed the connection, and now I have full reverse, and 1 speed forward. (Note - I have to start it in diagnostic mode: holding shift switches down when I turn on the key) If I start it with the (--) showing on the heads-up display, I at least have 1 forward and Reverse gear.

I'm thinking we might have a similar issue - why can the machine not identify Neutral? When I start the machine in the initialization sequence, and press UP,DOWN,UP, it then goes directly to (--). Whereas it should go to "N" and if you fully depress the throttle it should initialize the shift control motor. this is where I'm stuck.

Would like to hear if the new ECM helps you out.

Found the problem! Will post a new thread. Might help someone else.
SOOOOOOOOO.....What was the problem? I'm still having the same issue with mine, and it has to be something like the shifter linkage, shift switch, etc. or something to do with the Neutral position.
