P0740 error code dodge neon 01 se

I got this rear transmission that has no computer module witch i love it cuz no solenoids to mess with i guess. it separates from all neons on web i am trying to match. so it lags on final gear n so it hard shifts to second witch i feel like am racing all times. and this other problem i guess its causing it witch is the master cylinder brakes and so it losen presser. could it be brakes system?

Hi,

Here is some possible reasons why your transmission is having those problems .

* The gear shift linkage is binding
* There is an internal problem in the transmission
* The throttle cable is broken or disconnected
* The vacuum modulator on the transmission is faulty or the vacuum line is damaged
* The electronic transmission control circuit may be faulty

SOURCE: where is the shift solenoid located on a 2003 dodge neon sxt

the trans shift solenoid pack is bolted to the side of the trans closer to the radiator. it is rather large and there are three 10mm bolts holding it to the trans. it is under the input speed sensor and just under the spot where the cooler lines go into the trans.

You need a pullers to get it off.But if your lucky putting a screwdriver between the drum and back-plate and pize it when your hitting with a hammer it may come off.good luck.

2005 cts won't sift out of park, press the brake pedal and start the car, just won't shift out of park


You probably have a problem with

Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components.
• The automatic transmission shift lock control solenoid
• The brake switch
• The rear integration module (RIM)
• The transmission control module (TCM) or powertrain control module (PCM)
With the ignition ON, battery positive voltage is supplied to the automatic transmission shift lock control solenoid from the ignition 3 relay. The automatic transmission shift lock control solenoid is controlled by the rear integration module. When the rear integration module (RIM) receives a class 2 serial data message from the transmission control module (TCM) or powertrain control module (PCM) indicating that the shift lever is in the PARK position the rear integration module (RIM) grounds the automatic transmission shift lock control solenoid control circuit. This causes the solenoid to energize mechanically locking the shift lever in the PARK position. When the driver presses the brake pedal the rear integration module receives the brake applied signal and turns off the ground to the automatic transmission shift lock control solenoid control circuit. This allows the shift lever to be moved out of the PARK position.

Tip

I get code p0700 after an OBDII scan.


P0700 Transmition Control system is the transmission control module.
The transmission control module is a separate computer module, you need to read codes stored on transmission control module.

If there are no transmission code stored, then there is a bad Transmission Control Module (TCM) ground circuit or a bad TCM. In that case the ground to TCM must be tested, and TCM eventually replaced.

Faults that can cause troubles when shifting from first to second gear are : transmission fluid, speed sensor, TPS, transmission shift solenoid, gear box problem, TCM, neutral switch, torque converter problem.

The best thing to do is scanning TCM codes.

Won't downshift


Hello Bry Covel,

The kick-down has always been a function (re-action) of the throttle position... traditionally handled by an actual vacuum connection or linkage attached to the throttle.

In your 4 Speed Auto it is a kick-down solenoid
(See below: $140).

Modern cars have improved this with TCM (transmission control and engine control module connections (ECM)).

Your problem could be a connection between either module or an actual problem with the TCM or the solenoid it drives..

The factory manual would be the ideal source... but
you can also see technical bulletins and schematic drawings at BBB industries (also below, registration required).

4 cyl. Auto trans. in limp mode. takin the shift solenoid out to re build it i fnd ripped wires. My question may seem should i re connect the first or cont with the shift solenoi


Unfortunately, you should have gotten the diagnostic codes for the transmission before messing with the shift solenoid. Most of those dodge shift issues are caused by input and output speed sensors.

I have been getting the code p0740 it says something about the torque converter clutch circuit. it doesn't seem to be going into over drive. dose anyone have any suggestions I can try.


On some cars, there is a TCC solenoid in the transmission which can be replaced by removing the bottom pan. In some cars this solenoid can't be accessed without major disassembly.

Where is the speedometer on a 1998 dodge neon


The speedometer is in the instrument cluster. The speed sensor, I suspect this is your true question, is located in the transmission. If you look down, I know its difficult to see, where the dipstick tube goes into the transmission you will see a big electrical connector just to the right as you standing in front of the car. You will see the two rubber cooler hoses right above it. There will be a white plastic piece with a two wire connector right under those. That is the input speed sensor. This is not the part that needs to be replaced. The output speed sensors, the part that sends the speed signal to the computer, looks exactly like the input speed sensor but is located about 6-8" more to the right of the input speed sensor. Sometimes it is easier to spot from under the car.

If that sensor is bad it should flag a P0740 code in the pcm letting you know there are transmission codes stored in the TCM. A higher end scan tool (not a code reader) will be needed to get the codes from the TCM (transmission control module)

Hope that helps.

P0740 honda odyssey


P0740 Honda - Transmission Lock-Up Control System Fault Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness is open or shorted
- Torque converter clutch solenoid valve circuit poor electrical connection

Tech notes
On some Honda vehicles the P0740 code may be set by an overheating torque converter problem which is caused by an insufficient flow to the torque converter release circuit.

P0740 Honda Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

Loss of power, transmission issues


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.
