p0944 loss of hydraulic pump prime free sample

The P0944 code is defined as a loss of pressure or “prime” for the transmission’s hydraulic pump. It is most common with Dodge/Jeep vehicles, but is also used by some other manufacturers, including Volkswagen.

If your car’s Check Engine Light comes on and the P0944 code is stored, it means that the computer has noticed a significant drop in transmission pressure and that the pump has both lost its prime and failed the prime test. The prime test is run when the transmission slips while in any forward gear, and a no pressure situation is indicated by all pressure switches.

While the P0944 code indicates a loss of pressure and prime at the pump, there are a number of actual causes for the problem. These include the following:

There may be one or more symptoms experienced with the P0944 code, depending on the severity of the situation and how long it has existed. Symptoms can include:

Diagnosing the P0944 code starts by connecting a handheld diagnostic scanner to the car’s computer. The mechanic will read all the codes stored in the computer. Generally, the codes will be cleared and the vehicle test driven to determine if the codes will reset.

The mechanic will also conduct a shift lever position test using a scan tool. If the shift lever position test is passed, the mechanic will move on to testing the pressure in the transmission line. This is done with a scan tool and the engine operating, with the transmission in park. Note that the transmission should be at operating temperature for this test to be accurate. Depending on the results of this test, the mechanic may also need to test the transmission line pressure in both drive and reverse using the scan tool.

The mechanic may also need to check the internal seal for signs of leakage. If there are signs of a leak, the seal will need to be replaced. If there are no signs of leakage, the pump may need to be replaced. It may also be necessary to remove the transmission fluid pan and inspect the filter for signs of damage.

One of the most common mistakes with the P0944 code is not allowing the transmission to come to normal operating temperature before testing pressure. This is necessary because fluid pressures are higher when the transmission is cold, which can cause false negatives to the test.

The P0944 code is very serious, and it should be diagnosed and repaired immediately. If the problem is left unhandled, it could result in a situation in which the transmission will not engage at all, meaning that your car will not move.

Transmission related problems are always serious concerns. If you’ve noticed the Check Engine Light on and transmission operation problems, it is vital to have the situation diagnosed immediately. However, note that P0944 is not used by all manufacturers, so it is possible to experience similar symptoms but not have this particular code stored in the computer.

The P0944 engine code indicates a problem with your car’shydraulic pressure unit losing pressure, which is vital forproviding hydraulic pressureto the motors, cylinders, and other parts of the hydraulic system.

If your car is showing the P0944 engine code, there may be afaulty component in the transmission hydraulic pressure unit or pumpwhich is causing a significant drop in pressure.

The hydraulic pressure unit includes a motor, fluid reservoir, and a pump to form a self-contained unit. The unit applies hydraulic pressure to drive the motors, cylinders, and other parts of the hydraulic system.

The P0944 engine code is very serious and should be dealt withimmediatelysince it is a transmission-related issue. Without fixing the problem, your car may be unable to move at all since the transmission is unable to engage.

It may be possible to fix the P0944 engine code at home, but you mustdiagnose the issue correctlybefore beginning any repairs. Depending on the source of the problem, you may need to:Replace a faulty pump

Incorrectly performing these fixes could lead to highcar repaircosts. If you’re not sure what repairs your car needs,it’s a good idea to bring it to a professional for a thorough diagnostic inspection and repairs.

If you do decide to repair the P0944 code yourself, you’ll need to follow these steps:Identifythe correct parts and transmission fluid your vehicle takes

Inspectthe hydraulic pump unit to find any damaged components. Run the engine for a few minutes before checking the transmission fluid levels with the dipstick

One day recently, I found that while I was stopped in traffic, my car wouldn"t move while it was idling. For the rest of that day, I found that it wouldn"t move forward while idling, or move in reverse while idling.

The first mechanic that looked at it told me that the hydraulic pump didn"t have prime clearance (something like that), and that the entire trans would have to be rebuilt.

After that first day, the car is back to running normal as it had before, I"ve only run into the issue with the trans recently, for a fairly brief period of time. Part of me thinks "Hey, it"s not currently an issue for you, and when it was, once you revved up the car over 1000 RPMS it drove fine, so you should be able to go down the highways just fine for that 1000 mile trip either way", but i"m sure that it"s an issue that might deteriorate and cause other issues if I don"t get it fixed.

Now that it"s been driving normally for two days, the check engine light has since turned off, though the second mechanic has told me the codes are still there for the Trans control system.

This bulletin involves verifying the build date of the transmission, and if necessary, the replacement of both the cooler return and sump filters in the transmission.

The customer may experience an initial delayed shift engagement following an extended off (not running) period of time, generally after being parked overnight. The initial shift engagement may feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine start.

The customer may also experience a MIL illumination. Investigation may determine that the MIL is due to one or more of the following Diagnostic Trouble Codes (DIG"s):

The delayed engagement and MIL condition (DTC"s) may be caused by a suspect transmission cooler return filter with a part number of 04799662AB. A suspect 04799662AB cooler return filter may cause the transmission sump filter to split at its plastic-to-metal crimp. If the transmission sump filter becomes split at the crimp, then one or more of the above DTC"s may also occur.

3. Inspect for the transmission build date (Julian date) (Fig. 1). The transmission build date can be determined by inspection of the 20 digit transmission identification number (DDDYxxxxxPpartnumber). The transmission identification number is stamped on the left side (driver side) of the transmission oil pan flange. The first four (4) digits of the transmission identification number are the transmission build date, in Julian date format. An example of a transmission identification number would be 101510492P52119684AA. The first three digits ( 101 ) of the identification number equal the day of the year, in this case 101 equals April 11. The fourth digit ( 5 ) of the identification number equals the calendar year, in this case 5 equals 2005. So 1015 equals April 11, 2005.

5. If the vehicle has the above condition, and if the transmission Julian build date is on or between the range of dates listed above, perform the Repair Procedure.

DO NOT use a replacement cooler return filter with a part number of 04799662AB. This filter is suspect of causing the above condition. The cooler return filter part number is stenciled on the side of the filter"s metal case.

Always install the sump filter seal to the bottom of the transmission oil pump first, then install the sump filter to the oil pump and previously installed seal. DO NOT install the sump filter seal to the sump filter and then attempt to install both to the oil pump.

Hi, thanks for the response, but something seems a bit off track in two directions!(!) After giving the specs I was sold a sensor even by the dealer. But after reading all the diagrams I hunted, the location still could not be found; then I now assumed along with one guy that everybody is giving me information for an automatic transmission when my truck is a manual transmission. And also based on other cars or trucks. I am not hearing nothing about the 2006 dodge Dakotas which is my truck. Even on you tube everybody is talking about the rams and not the Dakotas.(2) nobody can still tell me if the 2006 manual transmission of the Dakotas carry input/out speed sensors or not and where they located. If they do carry any. Cause all the info diagrams I get seems to be for the automatic ones instead. So I want persons to understand that my problem of rough shifting from 3rd to second or not allowing to shift down from 3rd to 2nd is in a manual trans. Not automatic.. So is there anyone out there who is familiar with the 2006 Dakotas with manual transmission, and has shifting problems; like that that I have experienced. So once again I have a speed sensor in my hand and cannot find where to put it cause it was bought under the specs but it"s location cannot be found; suggesting that it belongs to an automatic truck instead of a standard one. And 2 no one can still tell me why the truck won"t allow shifting down to 2nd from 3rd unless it is slowed down to 4 mph. Please review as the answers I got is for automatic; mine is standard(manual) transmission.

Where are the input/output speed sensors on this engine transmission, or the directions given is related to automatic trucks only. Cause none is found on the side of the transmission where most people say they are. So does this engine have them or not?
