Autocommand stuck in low range

[grangenolvinfarm]

Hi,
I have a 2017 T6.145 AutoCommand.
It is currently stuck in the lower of two gears and won’t drive past about 10m/h
I have a 2019 T7 AC and I know by pressing two buttons I can lock her in low range, this T6 however does not have this option to lock it and is still displaying speed to up to 50k.
Any advice welcome?
Thanks

Have you tried calibrating? That would be the first step.
If it fails possibly blown side cover gasket stopping the synchro change.

Last autocommand NH I knew having this problem ended up in dealership in two halves...

Clutch pack gone?

How do you calibrate it?

 

[grangenolvinfarm]

Calibrated it and no change.

I take it calibrated fine then with no errors?

Yes. Calibrated for a few minutes then showed done.

Bit of black smoke coming out of exhaust, also very sluggish up very small hill.

With ours. If you shut it off. Then turn it on again fixes it. Hasn't done it often. But that's always worked when it has

Has been doing this for past couple of days. Started with one of the workers driving home with trailer.

Get a diagnostic lap top on it, no point guessing.
My T6 had the shakes a few years ago, was fearing the worst, diagnosis revealed two sensors gone, relatively cheap fix.

Dont suppose you can remember what the values for A and B clutches were. Should be a similar value and take a similar time to calibrate.
The fact that it calibrated suggest in theory the mechanics should be fine however a buggered clutch pack can still calibrate but not drive. If one has a vastly different value to the other or takes a while to calibrate your trouble could be there.

When you say won't drive past about 10mph is Speedo working?

Will do it again tomorrow and record it. Thanks

Sorry after further testing it's going any speed up to 25k. Just depends if going up or down hill. If straight does about 14Kmh

Is there a snowflake picture on the screen?

 

[Thepowerofdensil]

Won't calibrate with the on

I suspect you have clutch slippage, think you will need to make a phone call and get someone to look at it sorry

We have had a mechanic from dealership out and plugged it in and no faults appeared on his computer. He believes the clutch/trans is okay and that the problem is the tractor is lacking HP. He tested the turbo and changed fuel filters but to no avail. He wants to put it on dyno but I am reluctant, it's two hours away by car.
The tractor is just lacking power, I don't feel the gear change or see it in the revs but he tells me it's there.
Any one have any other ideas on why this tractor is not producing the HP it should be, 3000 hours or so.

Can you get it onto a pto implement like a slurry pump? That would tell you if its down on power
