I don’t know if changing the oil feed pipe (page 2) helped. Or the shift motor most likely, I believe the friction in the motor was prevented the shift from making a complete shift. Changed the angle sensor but that didn’t help early in the game. 

im far from an expert but I wish I was. I’m always interested to learn about complex testing of electric components and that as a mechanic I am learning try get better with it. I just appreciate the input you experts have in your experience 

Testing it a few more times you flip the key on the neutral light stays on and the displays N great! It i’m shifts and to first and back down to neutral I drove it around for about 45 minutes testing every option and button mode gear works alright. Hopefully it does for him 

Thank you everyone especially jeemwm69 for the hot tips and encouraging ways of doing things. 940$ parts 3 hours labour I’ll never take a Es job ever again haha 

Parts 940$ labour 3 hours I’ll never take on another Es job ever. Thank you everyone who chimed in with hot tips and encouraging ways of doing things. 

Oil level good, turn key on — displays, starts without need of hand brake application. Wait 2 seconds N comes on. Button shifts up all 5 gears and automatically downshifts for you! 2wd 4wd works great! In auto and esp! It kinda shifts hard!!! but it shifts and displaying!

now when you turn off the quad in neutral and turn on again — is displayed,, start the machine and wait 2 seconds N is displayed
That’s a little weird but it shifts and displaying 

Used the emergency shifter to put it in neutral by feel no N light, displays ~ no codes, started off for 5 secs upshifted display still ~ then I down shifted shut off the machine checked the oil 

now I put 5 litres of oil  in not a drop on the stick but the right hand side fill port is to the rim!! Wtf now it’s not draining into the sump 

Got oil I don’t know what as used in the past but I have Honda 10/30 in it,  Put in the new shift motor tonight

Maybe i missed it, but just curious what oil you are using 🤔

Honda 10/30

Enough with the sensors!! Haha frig 

I’ll do as you say with the relay

i must be able to reset the bank sensor? Jump it to try. maby I’ll youtube it or find out how 

No start now, did when I took it apart. turns over, great spark dry as a bone pulled it 3 times. Never drained the fuel  charged battery. I hear the fuel pump full tank of fuel. What did I do!

It’s a customers quad actually he’s crying for it. I will Never take a electrical job again.
It’s apparent the drag on the shift motor output gear is to much for the return spring in the transmission to return to grab another gear. Don’t know if that’s a huge deal. He did say it’s his 3rd shift motor 

anyway I’m working late on the quad to get it on it’s wheels and do some tests if I can from the manual, chime away 

I’m in Canada I’m not even going to try to order state side again. I wonder if their as good as Honda 

347$ for a shift motor holy cow!

good lord, i envy you quad doing all this, i'm sure glad i stick with manual shift models !. i would have to check into the nutt house after dealing with auto/es models after seeing what you are going through !..lol.

Oh they are a toilet!!! no man in their right mind take a Es quad into the bush with them here it’s a unspoken rule lol you will walk home!!! You will have issues lol

the dude is crying for it and I’m trying  so hard for the guy. 
now that it’s together I can try testing sensors n stuff more seriously 

Ok I put it all back together before I put it down on its wheels I tried using the manual shifter with the motor installed, I was only allowed to get one shift and it felt stuck and would not rachet back to grab another gear, I then unbolted the shifter motor and I heard the rachet return “ free up” without the shifter motor installed I can shift through all the gears with the manual shifter. The gears are all clean and lightly greased.
Somthing with the shifter motor is binding up with the shift change it’s like sticky or somthing.  you can feel the resistance with the motor on. The motor output gear seems to spin fine by finger 

Without the motor bolted on it makes firm sure shifts like it should and returns ready for another gear.. I’m getting a shifter motor tommaorow. Maby slop in the gears.. agh 

FINALLY got my gaskets and o rings to put it together. 

That’s just a big 3 jaw ThTs all I need I thought it had to thread onto the snout special tool, I have a large 3 jaw I’ll try tonight! Jeep I appreciate the tips you have! 

I’ll buy one in the link you posted thank you I have to borrow one from the Honda shop nearest AutoZone is 3 hrs away 

Yeah I got a rent or clutch puller installer to remove the center clutch, to remove the spacer to put a gasket on 

I got the front cover off doing some inspecting I’m looking at the oil feed pipe and it looks worn cavitated. I don’t think it supposed to look like this. Loss of oil pressure? Somthing get into a fight with it?

amazing with the tool now with the atv ! up i get a Neural Reverse 5 fowards . I never removed the VB but ill have to re seal the case and some o rings possibly, well frick. I have a manual now that sorta helps but i need to further test my switches and sensors.

 Correct, you’ll have to pull the front cover. 

 

It’s easiest if you remove the foot wells and get as much room in front of the engine as possible (by removing things) and then stand it up on the rear rack. They will stand up on the rear rack and rear wheels sticking straight up in the air.  Unhook wires on the valve body and be careful not to break the plugs off of the valve body as they are pricey. If I recall correctly you’ll have to unhook the radiator lines as well. Clamp them shut and tuck them up out of the way.

 

 

 

Then you can remove the front cover and you should be able to see what you’re looking for. 

ok after a few cuss words and trying I got the front cover part ways off, enough to see the return pin appears to be there not broken! Frick back to the drawing board, put it back together test the shift position  switch, maby a motor, maby get a real 500 FA manual 

the thread you posted about jeep describes the issue perfectly. yes i use the wrench to go from N to 1st/2nd there's a definite shift, Display is somtimes showing a gear sometimes showing --. i let go of the tool and it feels like it does not return to center or "rachet" as toodeep describes to grab the next tooth, the gear display is doing the same thing. It bangs HARD into reverse with the Reverse handle and the shift buttons, i only get a N 1st 2nd shift somtimes with the button until it locks up 

no i did not check the shifter switch thats the gray plug. i could not understand the instructions laid out in the manual 

plus talking to the guy today, he says "oh that pin prolly broke again!! frick 

im going to go into the front cover as jeep describes, not the rear cover correct?

So you can't shift it manually past first? 

 

Wonder if you have the "broken return pin" that I've seen referenced on a few of these machines.....

 

@toodeep @Melatv any ideas?

 

Look at posts 22 and 23 here

 Correct I definitely found neutral and one forward gear. Won’t go past that and it feels like the shift shaft is binding I would say that a pin is broke. 
that thread describes exactly what I’m experiencing, major tear down it says. awesome now we’re getting somewhere, I am so thankful thank you. Job  is not done yet

tried to probe the 3 wire angle sensor, couldn't get a voltage increase or decrease. not sure if its possible to test that way
