I thought I did. Is this possibly why it's shooting me a new code? I'll try it again.

 

I have to admit my diagnosis was wrong above. I never read the Rancher 'AT' part, sorry....

That's exactly what it was! Went for a two day ride and it worked great. You saved me hondamechanic. Thanks for the help brother.

 

I have the same machine (05 Rancher 400AT) and exactly the same symptoms as herby posted. I also notice that if I stop fully when the problem occurs then the ES motor will sound and the shifting gets back to normal. It is like the ES needs to catch up. It only happens at low speeds in auto shift mode. I had been doing some towing before the problem started but it was just a brush mower.

My angle sensor checks out ok and no issues with re-initializing. Oil is also fine. All electrical connections are good. One of the posts I read suggested it may also be battery related? Battery seems strong - no problems starting. Any other suggestions? Are there any tests for the ES motor itself?

Thanks!

The angle sensor on the TRX400FG/FA is behind the left floorboard ..

so you guys think if i did this to my four wheeler that is would help my prob also?

 

i cant see the pre-load instructions . my 2005 350 rancher wont start with the button ,it will start by hand . and if i jump the selenoid the starter starts it but it will only shift once then i have to shut down and turn the key back on . with ignition on it will go through all gears . but not running . neutral indicator light stays on in all gear positions.help ?

 

The 400 FA has a TOTALLY DIFFERENT GEARBOX TO THE 350ES so forget everything in this thread and start your own, or read the hundreds of posts about 350ES and 450ES and 420ES machines on here. On the 350ES a rotary switch in the gearbox switches with each gear to a separate wire, the whole bunch of wires go to the speedo where they signal the gear indicator display and the neutral and reverse lights. If the switch goes wrong and is always showing neutral this would disable the gearbox as described, one gearchange then the fault code should come up in Morse code on the display. However this doesn't explain no electric start. Try removing the three pin diode, it is a small black box in the fuse box,
