P1000 '18 P1k-5 shift help

[sozzy]

Ok, new to this site. I've searched all over the interwebs looking for answers to my situation but to no success, so I joined the site so I can ask exactly what I need...

I purchased a 2018 P1000-5 a couple months ago as a basket case. Wasn't running. I adjusted the valves, replaced plugs, changed fluids and filters, etc. And got it running. It had a tick which I narrowed down to a chain guide. Had to remove the rear transmission plates, oil tank, etc ( forget the actual nomenclature...) to get at the chain guides. Other than the tick, it ran well and shifted fine in auto and manual.

I've got it all back together and it will not shift out of first. Auto or manual. I can't even get the manual bypass shifter to work ( the manual mechanism next to the shift motor). I did a clutch relearn and it's still not working. It will run ok in first or reverse, high or low doesn't matter. After running for a bit, it will shut off and show a code 57. Turn the key off then back on and it starts right up again.
I ordered a new angle sensor, but am not sure that is the issue as the manual shift mechanism doesn't work. Just turns and turns. I took apart the gear reduction stuff and it all looks ok. I can't seem to find a schematic showing the manual shift mechanism... Only the gear reduction section.

I also took the shift motor out and had my wife try shifting in manual mode with the paddles and the motor seems to be working, though I will probably pull it back apart and clean up the brushes.

Anyone have any advice? What should I check on the manual shift mechanism? I'm really thinking this is my issue, like I didn't reinstall something correctly.

Being your first post you better get a pic of that rig posted here before the cops get here. Then you will get some ideas of where to look. Lots of very knowledgeable and experienced fellas here. Good luck!

Welcome from Michigan.

Yup, your first post so….
Pics Or It Didnt Happen!

I've searched all over the interwebs looking for answers

But did you use the search on here? 🤔
Also. Need Miles, have the clutchs been updated, and was it ever swamped will help us too.

 

[sozzy]

Yes I used the search. Couldn't find what I need.
No pics. Hands were covered in oil and couldn't take any.
12,xxx miles
clutches looked really good, not sure about any history regarding updates/ service. Really don't think my issue is clutch related. It shifted fine before I tore apart the back plates to fix the chain guide.

This is what it looked like when I brought it home...

I had a similar issue w the Donkey/P5 after the big bore kit, I had the angle sensor clocked 180 degrees out, might be worth checking

Should have a new angle sensor by Friday... I'll check it then.

Does the manual shift shaft return when shifted? Like it has spring tension?

No. Just turns. Spins All the way around

Then the shift spindle isn't engaging the return spring on the pin inside the rear of the engine. You may have slid it out some when removing the engine cover.

Tale the cover off behind the shift motor first and make sure everything there is correct. But it's sounds like the the engine is coming back apart.

Code 57 is being thrown because the shift motor is trying to shift but it doesn't see the shift happen or it returning correctly.

That's what I needed, thank you. Anyone have a picture of what it should look like? The schematic on line is not great and I don't even see the manual mechanism.

If you upgrade your membership you will have access to the service manual. Being this deep into it sounds like a manual would be handy.

I'll post a photo from the manual tonight

Just removed the shift motor and gear reduction stuff... Realized the pie shaped gear wasn't engaging the reduction gears. It has plenty of spring tension, just not making contact. I found I was able to pry it from the splined shaft, which luckily was not keyed. I reset the gear onto the shaft so it was engaging the reduction gears. Now the manual shift mechanism is spring loaded.
While I had it off, I took apart the shift motor and cleaned the brushes. Bit of a PITA to reassemble with ham fists, but I got it back together.
Did a clutch relearn for good measure and went down the road for a test drive. Seemed to shift pretty hard at first and manual mode worked well but it did stall a couple times and gave me a code 27 and 52. I'm thinking the new angle sensor will fix the 52. Should be here by Saturday. I think the 27 is for an O2 sensor so I'll have to get a new one too.

Are the codes flashing on the gear position or CEL?

You won't get an O2 code on the gear position and O2 sensors are always code 23

Code 52 is a NO 2 EOP sensor if im not mistaken. Check the ground next to the starter

 

[sozzy]

It's flashing on the gear position. What is 27 then? Grounds are good.... Tightened them all when I was putting the machine back together. Don't see any torn or pinched wires going to the shift motor or solenoids, etc. I was having a helluva time trying to get the shift motor connected.

I'll have to look at the manual later
