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

Sean Pried it could be your A604 4 Speed Automatic Transmission Shift Solenoid which is located just in front of your transmission dip stick.

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.

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.

P0740 reading TCC solenoid problem. Can this be expensive to fix? Do I need a new transmission?


Your transmission is slipping in gear due to clutch band wear. It may be that this can be adjusted for comparatively little cost (as compare to a new transmission). Take it to a specialist for this kind of repair.

I have a 20001 Odyssey with 70,000. The check engine light and TCS light both came on. The TCS light has since gone out but the check engine remains. I went to an auto parts store and their computer came...


unfortunately it is. Contact your local dealership to see if it may still be covered under a warranty or not.

Customer Concern: The check engine light is on with the trouble code P0740 present. Tests/Procedures: 1. Test drive the vehicle and watch the tachometer. See if the automatic transmission locks up. If unable to see the RPM change, and the Engine Control Module (ECM) is turning on the lockup solenoids, then the problem has to be internal to the transmission. The transmission has an extended warranty from Honda for 7 years or 100,000 miles. Potential Causes: Automatic Transmission
Lock-Up Solenoid
Torque Converter
Tech Tips: TSB #02-062 Diagnostic Codes: P0740

Transmission light cod P0740


PO740 is a TCC/lockup code.TCC stands for Torque Convertor Clutch.In between the engine and transmission is a torque convertor.Inside the torque convertor is a clutch.This clutch engages to eliminate slippage inside the torque convertor.When a malfunction occurs in the system,which is activated by solenoids,and a computer,a TCC code will set.There is a diagnostic route specifically for that code,to determine if the malfunction is electrical,mechanical,or hydraulic.
