SOURCE: I got the code P0847

Does it have any shifting problems? Hard shift or slipping? If not you may just need the 3rd clutch pressure switch. It will need to come from Honda I don't know pricing but I would think less then $100 and shouldn't take long to replace.

SOURCE: Stuck in 5th gear

That just recently happened to me. If your stick wont move into any of the gears, then you need a clutch. But if you can shift into the gears but dont go anywhere, then you need a new transmission.

SOURCE: '02 ACCORD 1-2 Shift Shudder,

The shift control solenoid externally mounted on the transmission can fail and causes a harsh 1-2 shift. Replacing the shift solenoid and flushisng 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.

In both cases (CR-V and the Civic) there is a linear solinoid that can cause the problem or if not then a broken spring inside the transmission that can create the same issue. The cheapest thing to do is to replace the linear solinoid and flush the transmission. If there is no change then the transmission will need to be replaced. The spring is deep inside the transmission and would require complete disassembly for replacement, and it's ususally more cost effective to replace the transmission as a unit.

Honda has issued a bulletin on this issue. As far as I can recall it's been about 50/50 between the spring and the solinoid to repair the problem. Some customers choose to live with the issue due to the cost involved.

Hope helps.

SOURCE: Location of A/C compressor clutch relay for 2004 Honda CRV

its under the hood in the box near the battery on the drivers side. I believe its the tall black one, but I could be wrong about which one since there are a number of them-- I know its in that box near the battery though.

P1775 code in showing up on my 2008 jeep wrangler x. How do you fix that?

we can not answer what you can do or fix.
only how to diagnose, or is this just a please guess for me post?
got tools, got a real scan tool?
is this a 5 buck code reader that misses most codes.
or a real one (ask for good tools)
if a real tool, it will show all codes, and you must know them all
or go astray. P0841? present? too>?

42RLE box.::: one code only, my guess.

i have this car, (m/t) and full FSM, on it,
Ill decode this and tell you what page to read in the FSM
it shows what to do next and the tests to prove this out.
P= power train
P1 means factory code ( so dont read ford codes)
TCC means torque converter clutch. lock up device. failure.
that means transmission, (id didnt say its bad)
the transmission on your car is automatic, unlike my stick
it has a TCM brain, hidden in the PCM brain
but its real and there. for sure. inside.
and it shifts for you, this brain,. in DRIVE

here is the 1st page on this code. in fsm book.

The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission
fluid when the LR solenoid is energized. When the solenoid switch valve is in the downshifted position and the
LR solenoid is energized, fluid is directed to the LR element for 1st gear. When the solenoid switch valve is In
the up-shifted position (2nd, 3rd, and 4th gear) and the LR solenoid is energized, fluid is directed into the
Lockup Switch Valve which controls the Torque Converter Clutch. When shifting into 1st gear, a special
sequence is followed to insure solenoid switch valve movement into the downshifted position. The LR pressure
switch is monitored to confirm switch valve movement. If the solenoid switch valve movement is not confirmed
(i.e. no LR pressure when the LR solenoid is energized), 2nd gear is substituted for 1st. No 1st gear (2nd gear is
substituted). The transmission Torque converter FEMCC operation is inhibited. MIL on after 5 min. of
substituted operation.
Monitor Conditions
When Monitored:
Prior to a shift into 1st gear.
possible causes:

the book says have the dealer
do a full transmission check using there (unique) fancy tool..
seems to be good advice.

below is the interface tcm.<> box.
solenoid and read back switches.
if the trans is not bad, then this switch is bad (fibbing)
or the wires rusty there... re-seat them yet?

Using the switches also makes the shifting smother and saves fuel.

Error code PO 843

Hi there:
This is a Powertrain fault code, DTC P0843 - Transmission Fluid Pressure Sensor/Switch "A" Circuit High

Generally this could be some gear pressure switch located behind the transmission was broke. Other details in THIS LINK.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

D" blinking is showing on

The PCM senses an abnormality in the powertrain system. Get the code checked, probably a pressure switch though.

The flashing D is a warning signal that there is a transmission problem. Sorry. Below is Honda recommendation for fluid changing.

Also, you coould check this Honda Auto Trans Flush Procedure - Official

Hope helps.

2002 celica GTS Transmission makes noise when shifting souns like gears grind although clutch is pressed all the way down. Do not see where to check tranny fluid. I replacing the clutch difficult on this...

There may be several reasons for this. 1st, low transmission fluid levels can cause the gears to grind while shifting due to lack of lubrication. I would suggest checking the fluid level, there is a plug located on the side, in about the middle of the transmission which when removed should slowly seep oil from it. If it doesn't then you will need to add the recommended transmission fluid.
2nd, a maladjusted clutch can cause the same problem. Even though you have the clutch pedal to the floor, the clutch pressure plate may not be completely disengaging from the flywheel. This will cause pressure on the gears and synchronizers while trying to shift. I suggest having the clutch adjusted by a mechanic if you have never performed this function yourself. An inproper adjustment can severely shorten the life of the clutch.
The 3rd option may be a warn clutch component like the slave cylinder if equipped, the throwout bearing or even the pressure plate itself.
A visual inspection can be made of the clutch by removing the inspection plate from the bottom of the bell housing to view the flywheel and clutch. With someone depressing the clutch you should be able to see the clutch moving off the flywheel.
