What is worng whit my transmission
#1. Check battery voltage and battery cables. Voltage should be between 13.6 / 14.4 Volts.
#2. Follow all ground connections & make sure everything is snug.
90% of the time, the M and S will flash do to a loose batt cable or a loose ground somewhere, or even a dying battery that needs replaced.
Series II. Why is diff lock stuck in?
Most likely from lack of use. Alternatively the transmission is wound up where by you need to jack up both wheels on one side to release the load on the axles. Or you can take it on some long grass, sand or other slippery surface, belt it around getting wheelspin and it should pop out. Hold your hand gently against the stick while you do it and it should come free. Don't drive it any further than absolutely necessary on a hard surface to do this because damage will result. You can do it by dropping 2 wheels onto the verge so they slip a bit.

I had EXACTLY the same codes about a year ago. truck would idle roughly and then the ses would light up..exact same.....drivers side injector harness was partially disconnected. If I were you I would pull the passenger side first and maybe you'll get lucky... but on the other hand pull them both and replace both harnesses.

Clutch is soft,and very hard
Probably not a worn clutch, When the clutch plate get worn it tend to slip, so going into gear gets easier, not harder (but vehicle will not move in that event either)
You don't say the year, model or mileage so I only give some guesses;
- I suspect tat the problem might not be the clutch at all, but lay in the transmission or shift linkage. If the problem were the clutch, slave or associated linkage, the problem would show up in other gear selections.The reverse gear is more functional related to the transfer gears (Lo-Hi) than the main gearbox, so having it work easier in low-range might make some sense.
- I would first check the shift linkage to see if it is out of adjustment. If this is ok;
- Next I would expect to find a worn bearing(roller gear cluster) in the transmission, probably at the reverse gear shaft. This would involve a removal and overhaul of the transmission, and I hope this is not the problem.
My knowledge is from general transmission repair and operations. Maybe someone will be able to give you a more specific answer.
I how this helps. Let me know in comment section how it turns out.
