Question about difficulty shifting (and a lift)

[Madison Sully]

There is not a common outlet from the oil tank. The HCM has its own suction line from the oil tank feeding its own oil pump. There are no HCM oil pressure sensors so no light lights or warnings for low pressure in the HCM system. The oil light on the display is for engine oil. Different system using the same oil.

Pull the HCM suction line from the tank and inspect it. Should only take a few minutes. Just a pain to drain some more oil. See item 1 in picture. Banjo fitting.

Thanks for this, looks like a viable hint. The parts diagram I saw said this went to the motor. But not only does it go toward the HCM, it DOES have a strainer....
I'll have to do this probably on Thursday though; I'm tired, my wife got me a big Mexican dinner, I'm on my second beer, and I have to talk in front of people tomorrow.

By the way, #30 in the picture is a strainer, and that hose goes to the HCM.

Engine oil strainer is item 18. HCM oil strainer is item 30.

Just a side note. The HCM will not fill with oil until it goes through a couple shift cycles. So if it was not able to shift because of an electrical issue let's say. The HCM will stay in recirculating mode. Pump will be running dry. No oil at the filter.

If I'm hearing you right, what you're saying is this could be the strainer being plugged.
OR, it could be a bad gear selector switch (no signal to the computer that I want to change gears), OR it could be a bad gear position sensor (not sure how...)?

I suppose while I'm in there I may as well clean up strainer #18....

Gear postion sensor I don't think so. If it was. There would be a E in the gear display. Also the N and R lights would alternately flash.

Well, that's not happening.
:gaah:
I mean, WOHOO, something to do this weekend!

Gentlemen this is what makes this forum great, what a fantastic respectful exchange of info, and this is coming from a guy who is barely able to follow along. I don’t understand it all but I’m learning anyway, thank you. :bowdown:

Thanks Billy. I was looking at the wrong tank picture. SE5 tank has the extra hose...and I knew that! Thanks.

Hey Sully - as the proud owner of an SE5, you might be curious about all this:

Whoa, excellent, thanks!

I'll dig into it as soon as I can....

Those diagrams were very helpful.
Here's what I did today:
Drained the oil and checked the strainer. Nothing in it, perfectly clean.
Refilled oil.
Took the gear selector switch apart (felt adventurous). Nothing looking wrong. Lost a little ball and a nut, but that should be no problem to replace.
Thought, perhaps there is no priming of that HCM pump, so I removed the dipstick and slightly opened the HCM filter housing to let oil move where it wanted to by opening the top of an air space.
Tightened everything back up.
Started the motor.
Toggled the gear selector internal bits to change from N to 1. Couple tries later, THUD!
Back and forth from N to 1 to N a few times, satisfying THUD! going into first each time.
Everything so far with parking brake on, as the left control stuff is still in pieces.

So I'm left with either:
1. There was an air gap that didn't allow oil into the HCM pump. Note for later: fill the oil, Then install HCM filter.
2. There is a problem with my switch that, due to being disassembled, I can press the detentes further in than the assembled lever would allow.

:dontknow:

I'll report back once I get the switch reassembled.
Meanwhile, thanks all for the help, I'm most of the way done.

Alrighty, that was fun.
Got the gear selector assembly all back together, started it up, and ran it back and forth N-1-N-R-N-1-N-R-N a couple of times.
All seems well.
Going to put the panels on now, and go for a ride, hopefully before it starts raining. Again.

So I'm left with thinking (hoping) that the original shifting issues caused by a mostly blocked HCM filter.
And the problem after changing the oil was an air gap at the HCM pump.
Knock wood, we'll see what happens next time the system is hot after an hour or so riding.

Thanks again,
Sully

Went for a ~20 minute test ride, and I'd say it's 80-90% of the way from where it was to where it should be.
By that I mean, it shifts really smooth and easy now. Definitely better than before the oil change.
Tiny niggle though; it missed shifting N to R twice, but giving it perhaps 100-200 RPM worth of additional throttle and it shifted.
We'll have to wait for a long hot ride though; it's about to rain I think.
