About 5-6 months ago we purchased a 2012 JD 2154D with a 622B Waratah, about 14,000hrs on it.
We've done a good bit of work to the machine just getting it working again everyday, hoses and little stuff on the carrier itself + lots and lots on the Waratah, but nothing significant or extreme in the last 500hrs. Has been pretty reliable / very fast & powerful for the size / good machine / really good track power.
I run it everyday just about, but lately its been giving us problems. All started about a month ago, had been processing all morning, shut the machine down to eat lunch on a really windy and cold day. Went back to run and again and I thought the tracks had snow packed up / froze in the wind because my track power was about half of it should be and wasnt getting around real well.
Low range at full power is like half speed, like loading onto a lowboy - just creeping along. High range is like normal low, a touch faster maybe.
None of the other hydraulic functions seemed to be affected, just the tracking.
Fast forward, it was an issue on and off. Would start the machine and some days it would be totally fine; full track power even at cold start and ran great. Other days it would be in limp track mode and you really couldnt get around until the machine would hit 160-180 hydraulic temp, which would take a couple hours to warm up. But some mornings I can hit 150-170 operating temp within 10-15 minutes of processing. All same weather conditions.
Track issue wasnt a problem for 2-3 weeks solid, no issues at all. Move units and immediately back to limp mode for the last 4-5 working days. But now I can tell things are running slow on the machine and processor head as well, even when the machine eventually warms up to that 170-180 range, it just doesnt seem quite right.
Perfect example though, fire the machine up yesterday morning, put it in warm up mode - its 9 deg F out - and within 10 minutes everything is up to 144 deg F on hydraulic temp and tracks have full power. Past two days it didnt want to do anything at all, no power. BUT I had to shut the machine down to work on the head, which immediately put it into limp mode the rest of the day and I couldnt get the hyd temp to get past 140 again at any point.
Anyways... intermittent low track power (will shuttle between high and low just fine) that can hang around for a few days, or be gone over night.
Can have full track power, but if you shut the machine off, it will derate the tracks unless you warm it way back up to 180 deg, but still feels a little off / not as strong.
Some morning machine will warm to 150+ hyd temp withing 15-20 minutes of working, but other days it will take hours to hit that temp.
Used to have full track power and hyd function even when machine was cold and only hit 120-130 deg hyd temp for the day
Fluids are full , no leaks, I have on error for a SPN 29 FMI 4 Fault: Accel POS2 volt below norm or short low Corrective action: check sensor and wiring - always been on the machine since we bought it.

. Please post a picture of your monitor. I think I know which one you have, but want to be sure.
