Question about 1998 Dodge Avenger

Possible problem with Transmission pump and shift solenoids

My 1998 Dodge Avenger Sport is showing the engine code for "Shift Solenoid Malfunction" and has started making a whining sound which a mechanic said is probably the pump on it's way out. How costly are these repairs? Or is the transmission actually in need of replacement?

    yes the code checks out, a friend has a scanner. I checked the meaning of the code. I didn't ask for a full explanation from the mechanic because I'm almost afraid to know the answer. I've put more than $1800 into this car in the last few months, and I'm getting frustrated with the whole affair.

    Also, I don't know how long it's been whining because the power steering pump and rack were bad and noisy, but now that those problems are gone, I can hear the whining.

    well has the code checked out why is this code being set ask your mech that , a better answer would be good from your tech than just the frt pump is going out, make him exsplain why and why the code is being set kdc744

I have 2004 gmc envoy xl 5.3 engine the code po753 is showing up


You are starting to have a transmission problem. I know....the Envoy runs fine....well, this code is telling you that there is a beginning of a problem with your transmission system. It could be a wire, could be a rock that was ran over flicked up under there and possible damaged something.....
Bottom line, there is a an issue developing. Suggestion? Check with AAMCO...it is free and they can give you an idea what the seriousness is.
Trouble Code: P0753 (5.3L V8 VIN P Auto)
A/T 1-2 Shift Solenoid Circuit Malfunction (4L60-E, 4L65-E)
Trouble Code Conditions:
Engine runtime over 5 seconds, system voltage at 10-18v, engine not in Fuel Cutoff mode, and the PCM detected an unexpected voltage condition on the A/T 1-2 Shift solenoid circuit.
Possible Causes:
  • 1-2 shift solenoid connector is damaged, loose or shorted
  • 1-2 shift solenoid control circuit is open or shorted to ground
  • 1-2 shift solenoid control circuit is shorted to system power
  • 1-2 shift solenoid is damaged or has failed
  • PCM has failed

1998 toyota ob755 seems to shift ok but keeos calling out 755 cntl v B


- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid B valve
- Shift solenoid B valve harness or connectors
- Shift solenoid B valve circuit is open or shorted
these are couple causes to turn on your check engine light

When the a transmission solenoid is malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.

I changed the 3-4 shift soleniod but now i dont have any gear but 2nd and before we had 1-3 just not over drive. what could have went wrong?


There is no code that tells you to replace the shift sdolenoid. There is a code (P0783) That has a generic description of "3-4 Shift Malfunction". Please note that there are several things that can cause this code. This code DOES NOT mean to replace the shift solenoid without first diagnosing the other possible causes of this code.
P0753 is for the "3-4 Shift Solenoid/Transmission Relay Circuit" If this is the code you had, please note that this code is a CIRCUIT code. The circuit includes the 3-4 shift solenoid, the transmission power relay and all the the wires and connectors connecting the power relay, the solenoid, and the PCM together. In this case the CIRCUITS must be diagnosed prior to replacing ANYTHING.

With all that said, is there now, or was there originally any other codes in the system besides one of these? If so, what are/were they? It is possible that there is a relay fault that is causing ALL of the shift solenoids to malfunction. It is also possible that there is low line pressure causing your no-shifting problem. Then there is the question: Are you absolutely certain that you replaced the correct solenoid?

I have also seen the shifting problems worsen due to misdiagnosis. Example: the power relay is causing the problem...the 3-4 shift solenoid gets changed...the transmission valve body is now full of air because the transmission was drained and the shift solenoid was removed from the valve body causing the valve body to drain...everything gets put back together and the transmission fluid is replaced....Now the transmission will not shift in any gear because the valve body cannot purge the air due to the solenoids being inoperative. They were inoperative in the first place and are still inoperative because the wrong part got replaced. PROPER diagnosis and repair will get everything working again.

I would recommend starting over to see what codes you now have and diagnose the system accordingly.

CODE P0755 ON TOYOTA CAMRY DX


DTC P0755 - Shift solenoid valve B
This warning is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.

The P0755 code is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission will not shift gears.

Possible causes:
- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid B valve
- Shift solenoid B valve harness or connectors
- Shift solenoid B valve circuit is open or shorted

  • What has happened is your transmission solenoid pack has gone bad. Not to worry, this is an easy fix.

  1. You need to purchase a transmission solenoid pack and a gasket.
  2. You can take your chances with a salvage yard or you can get one off of e-bay for about half of what the dealer will charge you or you can go to the dealer.
  3. Pop your hood and look on the top of the transmission. That little black box is the transmission solenoid.
  4. Clean the area around the solenoid real well with a shop rag.
  5. Remove the connector hooked onto the solenoid.
  6. You may have a linkage to pop off.
  7. Now remove the long bolts holding it into the transmission.
  8. Now wiggle the solenoid out.
  9. Reverse to finish.
  • That's it. Real easy fix for this vehicle.

Just scanned my 1999 300m. It went into safe mode while me wife was driving it home- 2nd gear only. It had a code P1714 and P0700 come up on the scanner. I can't find anything about the P1714.

Code p0750'p0755,p0765 and misfire when put in drive 1500 rpm


P0750 has to do with the Shift solenoid A its a circuit malfunction. Could be related to or caused by the wiring, shift solenoid, or ECM/TCM.

P0755 is also a shift solenoid B issue Circuit malfunction. Possible causes are wiring, shift solenoid, ECM/TCM.

P0765 is also a fhist solenoid D issue Circuit malfunction. Possible causes are in wiring, shift solenoid or ECM/TCM.

Misfire could be result of not shifting right and making vehicle seem as if there is a misfire but only a suggestion. But either way sounds as if you need to consult with a shop that can run tests with computer on transmission issues first.
