Your going to have to bring it in to a transmission shop and sorry could not help you with any other recommendation with the lack of information to your car's year and engine size, or the DTC codes. Good luck and hope it's just a transmission line pressure solenoid that when bad.

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.

2005 Dodge dakota transmission fluid light, wont go over 40


Yeah, generic "circuit malfunction" codes, it's a bad solenoid or two or valve body, either of which can be fixed by a HONEST transmission guy with high end diagnostic gear CHEAPER than a new tranny. OR...you can check solenoids yourself as you replace tranny fluid/filter, new fluid and filter did it for me once

My 2004 Pacifica wont start at all, the gear is in park but the gears on my dash panel are all lit up, no matter what gear I put it in. I changed the Transmission Solenoid cause their was a hole in it...


What Transmission Solenoid did you replace ? Pressure control solenoid ? Shift control ? P0522 code is not saying oil pressure is low , It's saying the PCM is seeing sensor pressure low ! Do you know how to test automotive electrical circuits with a volt meter ? An this has nothing to do with your gears lit up . Different problem .

My came with a code po734 is that a big problem?


DTC P0734 - Improper Ratio for Fourth Gear.
P0734 is detected when A/T cannot be shifted to the 4th gear position even if electrical circuit is good.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Tech notes: Start by inspecting the transmission fluid level and condition, and change fluid if necessary.


Test and check it and send us ypur comments.

Ford trauras trouble code 732 - was told transmission code 732 was being produced, what does a code 732 say?


P0732 FORD - Incorrect Second Gear Ratio
Transmission in second gear and the ECM detected an incorrect gear ration. This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Tech notes

Hope helps.

You may first want to check the condition of your transmission oil if it needs draining and replacing. If that checks out OK, you may want to check the solenoid on the transmission. See if it needs cleaning or replacing. If the solenoid is ok, you may want to check the transmission for the gear valves if they need cleaning. The valve for each gear that is not working may need cleaning.

Srs light.d4 light.not shifting to 3rd or 4th.wont always start


ok first the srs light is on when there is a malfunctioning with the airbag system, need to get that check out, and about the transmission you should check the fluid to see if it is on level of if it needs a flush.
Here is how to do that..
1- open hood 2- by the driver's side on the engine there is a dip stick that says transmission fluid 3- check if it is in right level
if it is not recomend a transmission fluid flush and check transmission
thank you good luck
