2005 Dodge MagnumRecently, I have been driving and while accelerating into 3rd gear, the car jerks, then I gear a thumping noise… What could this be?


RESPONSE

Since the thumping noise doesn’t occur until you accelerated into top gear I think it may be transmission related.  It would be a good idea to check the transmission fluid level and make sure it is full and looks nice and clean. If the fluid looks dark or burnt, there may be a more significant internal problem. Could be a solenoid sticking internally in the transmission. There may be a code stored that may assist in locating the exact issue. The Dodge Magnum came with 2 different transmissions, the 42RLE and the NAG1. You may want to have a reputable transmission shop perform the computer diagnostics with there scan tool since they are kinda of expensive. An average scan tool will not pull transmission codes, they just pull engine codes. If by chance you do have a good scan tool that will extract transmission codes here are the procedures to follow.

42RLE PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

Diagnostic Test

42RLE PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

Low fluid level can be the cause of many transmission problems. If the fluid level is low locate and repair the leak then check and adjust the fluid level per the Service Information.

Always perform diagnostics with a fully charged battery to avoid false symptoms.

With the scan tool, read Engine DTC’s. Check and repair all Engine DTC’s prior to performing any transmission symptom diagnostics.

With the scan tool, read Transmission DTC’s. Record all DTC’s and 1 Trip Failures.

Diagnose 1 Trip Failures as a fully matured DTC.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Repair as necessary.

Perform the Shift Lever Position Test. If the test does not pass, refer to Symptom test for P0706 Check Shifter Signal.

For Gear Ratio DTC’s, check and record all CVI’s.

Most DTC’s set on start up but some must be set by driving the vehicle such that all diagnostic monitors have run.

Verify flash level of Powertrain Control Module. Some problems are corrected by software upgrades to the Transmission and Engine software.

42RLE TRANSMISSION VERIFICATION TEST – VER 1

1. After completion of the Transmission Verification Test, the Powertrain Verification Test must be performed.

2. Connect the scan tool to the Data Link Connector (DLC).

3. Reconnect any disconnected components.

4. With the scan tool, erase all Transmission DTC’s, also erase the PCM DTC’s.

5. Perform *PRNDL FAULT CLEARING PROCEDURE after completion of repairs for P0706 CHECK SHIFTER SIGNAL.

6. With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Temperature is HOT, above 43° C or 110° F.

7. Check the transmission fluid and adjust if necessary.

8. If the Powertrain Control Module or Torque Converter has been replaced, or if the Transmission has been repaired or replaced, it is necessary to perform the scan tool Quick Learn Procedure.

9. If the Powertrain Control Module or Front Control Module has been replaced you must reset the Pinion Factor in the Front Control Module.

10. Road test the vehicle. With the scan tool, monitor the engine RPM. Make 15 to 20 1-2, 2-3, 3-4 upshifts. Perform these shifts from a standing start to 45 mph with a constant throttle opening of 20 to 25 degrees.

11. Below 25 MPH, make 5 to 8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.

12. For a specific DTC, drive the vehicle to the Symptom’s When Monitored/When Set conditions to verify the DTC is repaired.

13. If equipped with AutoStick®, upshift and downshift several times using the AutoStick® feature during the road test.

14. Use the EATX OBDII task manager to run Good Trip time in each gear, this will confirm the repair and to ensure that the DTC has not re-matured.

15. Check for Diagnostic Trouble Codes (DTC’s) during the road test. If a DTC sets during the road test , return to the Symptom list and perform the appropriate symptom.

16. Erase P0700 DTC in the PCM to turn the MIL light off after making transmission repairs.

NAG1 PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

Low fluid level can be the cause of many transmission problems. If the fluid level is low, locate and repair the leak then check and adjust the fluid level in accordance with the Service Information.

Always perform diagnostics with a fully charged battery to avoid false symptoms.

With the scan tool, read the engine DTCs. Check and repair all engine DTCs prior to performing transmission symptom diagnostic procedures.

With the scan tool, read and record all Transmission DTCs.

If the TCM detects and stores a DTC, the TCM also stores the vehicles operating conditions under which the DTC originally set and is located in scan tool under Environmental Data. Before erasing any stored DTCs, record any available data to assist in duplicating the conditions in which the DTC originally set.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Check connectors – Clean/repair as necessary.

Most DTCs set on start up but some must be set by driving the vehicle such that all diagnostic monitors have run.

Verify flash level of transmission controller. Some problems are corrected by software upgrades to the transmission controller. Verify no variant DTCs are present. If variant DTCs are present, perform their re spective test first.

If the TCM (EGS) is flashed, perform a EGS initialization with the scan tool to relearn variant coding.

NAG1 TRANSMISSION VERIFICATION TEST – VER 1

Reconnect any disconnected components.

Connect the scan tool to the Data Link Connector.

With the scan tool, erase ABS DTCs.

With the scan tool, erase PCM DTCs.

With the scan tool, erase TCM DTCs.

With the scan tool, display the Transmission temperature. Start and run the engine until the Transmission temperature is above 43° C (110° F).

Check the Transmission fluid and adjust if necessary. Refer to the Service Information for the proper Fluid Fill procedure.

If internal repairs were performed and the shift quality is still poor, it may be necessary to check the internal repair.

If the TCM (EGS) is flashed or replaced, with the scan tool, perform a EGS initialization to relearn variant coding.

If internal transmission repairs are performed or replacement of the Transmission Control Module, perform a TCM ADAPTATION procedure. (Refer to 8 – ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE – STANDARD PROCEDURE)

ROAD TEST PROCEDURE

Road test the vehicle. Make fifteen to twenty 1–2, 2–3, 3–4, and 4–5 upshifts.

Perform these shifts from a standing start to 72 Kmh (45 MPH) with a constant throttle opening of 20 to 25 degrees.

With speeds below 40 Kmh (25 MPH), make five to eight wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.

With the scan tool, read Transmission DTCs.

Problems with reverse and the issues only seem to happen when the temp gauge is reading at least 195+. Also really tgin trans fluis almost like water was added. Please help!

RESPONSE If the transmission fluid level is full and the fluid looks clean it would indicate an internal issue. Most likely a sticking solenoid or failing solenoid.

Automatic Transmission Operation

Your automatic transmission may have a shift lever located on the console between the seats or on the steering column. There are several different positions for your shift lever. If your vehicle is equipped with a column shift lever, it features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is in OFF, but not locked, there will be a small current drain on your battery which could discharge your battery over a period of time. If you need to leave your key in the ignition in OFF for an extended period, it is recommended that you disconnect the battery cable from the battery to prevent discharging your battery.
PARK (P)
This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily.
Warning! It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park . If you are pulling a trailer, see Towing a Trailer . Warning!  If you have four-wheel drive, your vehicle will be free to roll — even if your shift lever is in PARK (P) — if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear — not in NEUTRAL. See Four-Wheel Drive . See Shifting Into Park (P) . Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever; then, while pressing the button on the console shift lever, push the shift lever all the way in PARK (P) as you maintain brake application. Then move the shift lever into the gear you wish. See Shifting Out of Park (P) .
REVERSE (R)
Use this gear to back up.
Caution! Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped.
To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transmission, see If You Are Stuck:
In Sand, Mud, Ice or Snow .
NEUTRAL (N)
In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only.
Warning! Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed. Caution! Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle.
DRIVE (D)This position is for normal driving. If you need more power for passing, and you’re:
  • Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down.
  • Going about 35 mph (55 km/h) or more, push the accelerator all the way down.
You’ll shift down to the next gear and have more power. DRIVE (D) should not be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving. Select THIRD (3) when operating the vehicle under any of these conditions.
THIRD (3)
This position is also used for normal driving. It offers more power and lower fuel economy than DRIVE (D). You should use THIRD (3) when towing a trailer, carrying a heavy load, driving on steep hills or winding roads or for off-road driving.
SECOND (2)
This position gives you more power but lower fuel economy than THIRD (3). You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on.
You can also use SECOND (2) for starting your vehicle from a stop on slippery road surfaces.
FIRST (1)
This position gives you even more power but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.
Caution! Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

1987 Dodge D150I have a 1987 Dodge D-150, 5.2L, automatic transmission, 2WD, and would like to know if I could put a 5.9L motor in and still have the transmission bolt up without changing it out?


RESPONSE

The blocks are the same, just the 360 is bored out to a larger displacement. So yes the transmission should bolt right up without any issue.

V8 Engine identification number location — 1985–88 vehicles

There is a quick way of telling the small block 318 and 360 cu. in. V8s from the 400 and 440s. On the 318 and 360s, the distributor is at the rear of the engine, while the 400 and 440 cu. in. V8s have it at the front.

Transmission 1996 Buick Regal

Buick RegalI have a 1996 Buick Regal. Until recently, it’s ran fine. And then, this past Sunday (as of the time of this post), the RPMs began to shoot up to 5 and 6 and the car lost acceleration. I thought it needed more transmission fluid, but today I found out that I had put too much in it. So my dad and I drained the pan and refilled it, but the car refused to go into gear. Let me rephrase — it would go into gear, but it wouldn’t go anywhere. I found several posts on various sites about how it might be a transmission pump or a transmission lockup solenoid, but the results upon testing them were still the same — no acceleration at all. Does anyone know how this can be fixed without the need for a mechanic?


RESPONSE

If the fluid was burnt looking it will need rebuilt. If you hear a whining noise it is the pump.  If the fluid was pretty new looking then it is most likely an electronic solenoid sticking. This will generally set a code. The check engine light will not illuminate as it has to do with the transmission and not the engine. You will need a scan tool in order to pull the transmission codes. The codes will help point you in the right direction. Not much to do without the codes. Feel free to post them below if you have further questions related to this issue.

My 700r4 tranny went into limp mode due to a burnt 3-4 clutch. I bought a 2wd 700r4 (same year) for cheap with low miles. I want to know what I need to do to be able to drop my current 4×4 tranny and install the new 2wd 700r4 to convert it to 4wd. I have all parts for the 4wd.

Thank you for your time and consideration.
I have a 98′ Bravada and when I got it back from my mechanic this last time it was no longer working properly. From what we have come to understand he rev’d the engine with his foot on the gas and brake while in drive. So now the car will not take off from a stop in |D| – but will work properly if I shift from 1st, 2nd, 3rd, then into drive – and from there |D| will downshift automatically but not lower than 2nd.
ABS light is on and check engine goes on and off seemingly at random.
Does this seem like an issue I can duct tape without taking apart the transmission. Thank you again.

My car is stuck in 3rd gear and the CEL is on. Took the car to the local Auto Zone and had them check the codes. The code that came was P0750 which after doing some research points to a bad shift solenoid A. What would be easier or the best way to fix this? To either replace the solenoid or to replace the entire valve body? Also I wouldn’t know which solenoid to replace because I haven’t found a good diagram to go by.

Your question: “i have heard there are four different transmissions that came in an 01 buick lesabre so im told. i have a good transmission to replace the one that is out in my 01 lesabre. how do i tell which of the four is in my car and which of the four my replacement ought to be?”

While driving on the freeway at top speed all of a sudden I have no power to go forward. The engine is on, the RPMs engage when pressing the gas, but it had no power to go forward. I eventually coasted off to a safe location. The car will start and the engine runs but when put into gear I have no forward movement. What went out?
