Harsh Shifting of Automatic Transmission on Honda Civic

Problem Description and Possible Solution

The shift control solenoid externally mounted on the automatic transmission (non CVT) can fail and causes a harsh 1-2 shift. Replacing the shift solenoid and flushing the transmission with genuine Honda automatic transmission fluid may eliminate harsh shifting characteristics. A broken internal spring can cause the same issue. If the shift control solenoid does not repair the problem, the transmission will have to be replaced.

The transmission will not shift into gear. The problem happened yesterday. The car was driving fine and it suddenly lost power. Initially, the forward gears had no power and the reverse did not work. Now nothing works. What could be the problem?
Seems fine while driving, there is a slight hiccup between shifts 1-2 that wasnt there till recently, as soon as that started i havnt been able to get into the 4th all, so it shifts to the 3rd, and regardless of what i do it doesnt want to shift any higher. seems to happen fairly often in civics...
Felt and heard a clunk when shifting between 1st and 2nd gear yesterday. Now it wont shift into 4th gear, stays in third. Also does not seem to downshift properly. So when starting from a stop, feels like still in 3rd gear.
When i start it at first it shift ok but after awhile when it gets hot the gears won't shift.
We had severe driving issues and went to a mechanic to have the issue looked into and was inform that we may need to replace the transmission and the he researched and found this same issue with other hondas and he now is going to replace the solenoid to see if that resolves the problem.
Won't shift into first and slips and shutters. Then it seems to do fine in the upper gears.
I have a 2006 Honda civic that drives but does not shift to the next gear when i have it in drive.I think its stuck in drive low. Also the speedometer is not working.I was told if the speedomter does not work its because the transmission could be stuck in drive.Does anybody had that same problem let me know.

Thank You,
The engine light came on and a green flashing "D" led also began blinking. The 1st to 2nd shift is harsh and also shifting into reverse is harsh. From what I've been able to find online about this problem is that the Pressure Control Solenoid "C" unit is to blame as the ECM sets a P0970 error code that can't be reset.
My tranny seems to not wanna revert into the next gear at 30mph and at 55 I gotta redline it to pop into the next gear I have totally redonne the engine but not the granny I had my friend probe it to find the main computer chip to be faulty,he says the whole wiring and computer system has to be taken apart and replaced in a very careful way and if not done right I might as well junk iit.sometimes he too into the its either gas or electrical to start car and wants nothing to do w never cars,does any one know of a way to reset it back to factory or fix it without dismantling it?
Wen im in a stop I first had a problem with acellerating I kinda pushed me back and den got into gear and now is wen I start at a stop and accelerate fast it kinda haves like a 2 jump and I still have the previouse problem
My car is the 5 speed auto. 2006 civic coupe. My automatic transmission is having a hard time shifting from gear to hear specifically 1-2 I have a warranty on my car so I am debating whether to take it is or not I do not want to pay out of pocket for this repair.
hard to shift all the time;if pushing the button on the side of the driver'handle,nothing is changing.
