Code P2723 pressure control solenoid "E" performance or stuck off

you can check the transmission fluid if its ok and also the transmission pressure

There could be a number of possible reasons why your G30 Chevy van is not shifting out of 1st gear. Some potential causes could include:

1. Faulty shift solenoids: The shift solenoids are responsible for controlling the flow of transmission fluid through the valve body, which in turn affects the shifting of gears. If the solenoids are not functioning properly, it can cause the transmission to get stuck in 1st gear.
2. Low transmission fluid pressure: If the fluid pressure in the transmission is too low, it can prevent the gears from shifting properly.
3. Faulty transmission control module: The transmission control module (TCM) is responsible for controlling the shifting of gears in an automatic transmission. If the TCM is faulty or has malfunctioned, it can cause the transmission to get stuck in 1st gear.
4. Internal transmission issues: There could be internal issues within the transmission itself that are preventing it from shifting out of 1st gear. This could include worn gears or clutches, or other mechanical issues.

It is recommended to take your van to a qualified mechanic or transmission specialist to diagnose the issue and perform any necessary repairs.

no year car, no engine size, no transmission name , nor country
my guess this tranny A/t , fails 3 >4 shift/ that it?
fails to shift or shifts up and FLARE (aka false neutrals)
not told the problem at all just parts changed wrong
there are 50 causes (seals old and bad and leak vast)
and 20 or more bad symptoms on a failing tranny

TRANS UA-NCP25, (car code name)
TRANSVERSE BOX FWD.
BASE TRANS, AISIN, U340F-04A

THERE ARE MANY TEST. FOR ANY A/T
1: AFT not burnt, not overfilled or under
2: scans show what is wrong/ not scanned is no good.
3: line pressure port tested for a PSI in all shifted gears PRNDL.
4: if EBOX. , 3>4 solenoid bad, (not shifting to 4th)
5: PCVS some have pressure control valve, Ebox, to set or trim main line pressure. (as in modulated)
5a and newer have gear pressure detector switches.that can all fail if above fails.
6: all speed sensord good but the scans told you that if you looked.
7: endless leaks causes #3 to fail sure. its 20 years old why not?
maker AISIN , bet 1.
and some version of A340 but not told. ending in E,F,H,S
8:heat sensor in box (Ebox) that cause limphome mode to cool it down.does box work COLD"?
S code s Tip-tronic box,suffix code
my answer is mostly 2002 year, but NOT TOLD. U

not guess, learn that, or even read its side plate tag
huge evolution 2000 to now, for sure new pressure control
modulated solenoids and 2 or 3 speed sensors.
Any car made,if has EBOx, (means TCM brain shifted )
must be scanned first after levels ATF correct hot.

1700 is a generic code for many makes and models referring to a transmission issue.1751 is directed to the shift solenoid valve b. May be able to replace just that solenoid and be ok. Cheaper than a transmission.

Sometimes with code readers they get confused an just throw any old codes . Have it checked by someone with GM Tech 2 scan tool .

The code relates to a transmission pressure control solenoid that is stuck in the off position. The transmission is then limited to reverse and 3rd gear. You may notice some hesitation or sluggishness.

Good Luck.

code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)
code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again)
code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)
code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734)
code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.

Hello i can assist you your your fault code you have supplied indicates your pressure control solenoid "C" is malfunctioning this will cause your transmission not to shift properly and will stay stuck in separate gears including 3rd gear.I recommend taking your vehicle into a transmission specialist for proper repair and transmission service this is a delicate job if you have not performed such transmission repairs.You should not be operating your vehicle with this control solenoid malfunctioning.
