[@executor-li6ml]

Opel Insignia 2011 2.0 cdti 4x4 sport automatic gearbox.After flushing gearbox car violently shakes and makes noise while getting shifted to D mode.Service shop at first didn't put enough atf oil and that was happening,took a car back to them and they put the rest of oil in that was missing,same thing was happeing after just less in strenght.I took car back to them,they checked everything and said everything is fine,but it wasn't.I asked from them to check ecu,tcm and stuff.They reinstalled softweare and problem went away,now after 2 months it came back.I doubt there is any mechanical issue due to what was happening before.I would say it is has to be something with electronics.Opinions?!

After battery replacement, my Kia Rio 2015 shifts the gear very early. For example, I'm driving on gear 5 in the city with speed of 50 km/h. There's no code and I have been driving the car for week after with this condition. Any idea what the problem is?

HELLO! I've watched quite a few of your videos in trying to find an answer for the problem I have in my 2001 Dodge Dakota SLT crew cab four-door 3.9L engine! The truck always shifted a little funny, (after all it is a Dodge)! But last couple of months once it's warmed up and I start driving it trips a code, the P07020 Output Circut Code, Speedometer goes CrAzY and and stays in first gear! Prior to this I have, changed the Transmission Filter and Fluid. I changed the Governor Shift Solenoids. Changed the Vehicle Speed Sensor, (twice)! I reset the computer by disconnecting the battery cables, putting the two cables together overnight then connect the cables and drive it. As soon as it warms up it trips the code P07020, Speedo goes CrAzY and stays in first gear! I suspect I have a bad TCM however I wanted to know in my vehicle does the ECM power the transmission as well or there is indeed and dedicated Transmission Control Module and where is it on a Dodge Dakota? Best, JimiCactus

Can p0500 be on of the code that show if my time is bad

[@fixit3879]

P0500 - Vehicle Speed Sensor Malfunction Code. Possible causes may be Faulty Vehicle Speed Sensor: The sensor itself may be defective. Wiring Issues: Damaged or corroded wiring or connectors related to the VSS. Faulty ECU: Although rare, the engine control unit may be malfunctioning. Transmission Issues: If the VSS is integrated into the transmission, internal issues could affect its function.

2002 toyota camry xle has a hard shiftfrom 1st gear to second and no overdrive ObO shows po750 solinoid fault. Which solinoid is resposible

[@fixit3879]

The P0750 code on your 2002 Toyota Camry XLE indicates a problem with the transmission shift solenoid "A." This solenoid is responsible for controlling the engagement of the transmission for first and second gear shifts. A hard shift from first to second gear and the lack of overdrive can be symptoms of a malfunctioning solenoid or issues with the transmission fluid pressure. It’s advisable to inspect the solenoid and the related wiring. Good Luck!

Peugeot 4007 2.2 HDI. After starting, it throws the error, Transmission service required; and the transmission does not shift, it remains in neutral. In this case, the idle speed increases from 800 to 1100 I stop and start it several times and the error message disappears and it runs without error, but I can't start it more and more times. Diagnostics: It brought P0704 Clutch Switch Input Circuit Malfunction and P0702 Shift Control System Electrical Malfunction as transient faults. What causes the error? Thanks!

[@fixit3879]

Wow, sorry for your troubles. Hope you get it fixed. You might find this Video helpful: kzbin.info/www/bejne/inqmkq2in5J4bK8 Good Luck!

My dodge caravan 2008 is having number 2 symptoms problems

[@vickyokibe7678]

It will shift from 2 to to high gear and will not return to 1 Unless restart the car before 1 and 2 will work then shift to high gear

[@chriszatylny8645]

Are tcm on manual shifts?

[@fixit3879]

NO, TCMs are only on automatic Transmission vehicles. Gear input on manuals is provided by the driver. Good Luck!

[@CarspotAutoSales]

it was very helpfull

[@fixit3879]

Thank you!

What about P0965?

[@TerrySmitty]

Were is located at

[@fixit3879]

It may be located on the transmission, in the gearbox, or under the center console. It depends on the type of car. What type of car do you have?

[@toring61_52]

It's really sad that they even put computers and all this electronic 💩 in cars. Miss the muscle cars of their days

[@fixit3879]

We all have nostalgic moments, I hear you. However, I do like the advance electronics in modern cars, they are supposed to help us and improve cars. Although not always.

[@tomrogers4667]

What about P0890

[@fixit3879]

That is related also. Good Luck!

New trans car starts but will not move..

[@fixit3879]

Try the following, it might help: Check Transmission Fluid: Ensure fluid level is correct and it’s clean. Inspect Connections: Verify all wiring and shift linkages are properly connected. Test Transmission Control Module (TCM): Ensure it’s functioning and properly programmed. Look for Error Codes: Use an OBD-II scanner to identify any issues. Check Mechanical Parts: Ensure the torque converter and transmission mounts are correctly installed. Verify Gear Selector: Make sure it’s engaging the transmission properly. Goog Luck!

No reverse

[@fixit3879]

That is never a good sign. Good Luck to you.

P0600

[@fixit3879]

The P0600 code means there's a communication problem between the engine control module (ECM) and other vehicle modules. Check the wiring and connections, and consider having the ECM tested if needed. Hope this helps. Good Luck! What other codes or symptoms are you experiencing?
