Hello I’m new here, bought a 05 Honda rancher 400fa back in February, was told clutch was bad, so took a few nights out my week and got a new one put on about 4 weeks ago, took her out riding with no problems till later in the day she was shifting into gears hard so i called it a day, got back home drained the oil realized it was low from the drain plug leak i have so thought alright i will change the oil, pulled the carb to so i could clean it up, well put everything back together Friday night started her up and put her in gear no problems till i realizes with no throttle she is moves, and also the ‘- -‘ lines are up where it should say N at on my gear selection anybody got any idea? Thanks.

Welcome aboard. Very well could be the middle switch of the 3 shown here: https://www.partzilla.com/catalog/honda/atv/2005/trx400fa-a-fourtrax-rancher-at/rear-crankcase-cover

It is just under your left side engine cover and connector could have come loose when you were working on it.

Can you also describe with some more detail the "shifting into gear hard"? Do you mean difficulty with the sub-transmission going from D-N-R? Or the hydrostatic gear ratios changing while moving?

Going from N to D or N to R it’s hard getting it into those but i think that’s from low oil cause it’s fine now going into gear just starts rolling before i give it throttle at all

Ahh ok. If it's physically hard for it to go into D or R from N, AND it wants to roll on its own, that sounds like it is idling too high so the centrifugal clutch is partially engaging, adding pressure to the shift mechanism. Your difficulty shifting and rolling its own issues are related. Try adjusting your idle down. If idle is already down low, you could have an issue with your clutch weight set.

I was thinking idle to, so i took the carb back off and got everything set as low as i could, then put it back together and started it and got it to idle just above giving out, so i put it in gear and she rolled forward no throttle, I’m wondering cause before i pulled the carb and cleaned it, it was doing fine, going into gear hard but i think that was cause low oil, do you think a computer reset might help? The clutch i got was a used one but guy told me it worked fine when pulled from the bike.

I was thinking idle to high so i took apart the throttle cable and got it where it’s barely staying alive and then i put it in gear, and it just slightly moves forward, but i had no problem before i pulled the carb and cleaned it up, should i try resetting the computer? Like the manual says if you pull anything to do with the throttle should reset the computer, and with no N coming up on the dash when i start it all it does is blink those little lines

So with the idle too high, you did just try to adjust with the idle adjust knob first, right? I would not jump to disassembling the carb or removing throttle cable unless it had other issues while running.

The -- on the display when in neutral certainly could be the neutral position switch i mentioned first, or just the connection.

And you are correct about the manual calling for an initialization process if you remove the throttle cable. But I have not found that to be necessary. What you could do though is check ALL the electrical connections on the atv, do one at a time and add di-electric grease to each. Then replace that neutral switch if nothing wrong with wire and not a loose connection, and then go through the initialization process.

Edit: if you're confident idle speed is normal, and yet it is still wanting to creep forward when in D, this is not computer or elctronic related. The only thing that can make it want to creep forward while idling is the centrifugal clutch.

With the clutch, it didn’t do any of this before taking the carb out this past weekend, when i went riding it was perfect, besides at the end of the day with the hard shifting into D or R from N, i will double check all my connections tonight and maybe try resetting the ecu with the thing and seeing if that does anything, thanks

Can you shift it into D/R with the engine off? I have had the cables seize up & snap as well on them. Will the green N light come on at all?

 

[Deltag239]

Yes light comes on for neutral just doesn’t show the N on the dash, i haven’t tried shifting it off but if i remember correctly i think i turned it off in R and put it in neutral the first time i did it cause it scared me so i grabbed the brakes and turned it off in R, and went back into neutral perfectly fine

Ok, that makes sense. With the high idle, sometimes this can occur after it is extra warm from an extended ride, and like mentioned before, high idle contribute to the hard shifting. Still having trouble understanding why you took the carb apart at all. If idle was just a little high, a simple idle adjustment should have been all that was needed.

X2 to checking how the shifting feels while off like atc4ever mentions.

 

[Deltag239]

Took the carb off for a cleaning of the float, it was bogging down when first giving it gas, so i decided to take it off and give it a good cleaning, also forgot to check where the throttle cable was at when i took off so reinstalled and now it’s giving me issues when all i want to do is ride

 

[Deltag239]

Alright guys go in and out of gear like normal with it off, ran the codes that was in it and I’m getting 4 blinks with the little dots, also did the recalibration test for like when you get a new angle sensor, and it never got back to N just sat with - - sign right in the middle, no esp or anything under it, i pulled the angle sensor and forgot tools at the shop so i gotta wait for tomorrow to get it all back together and working hopefully
