Ask a Car Question, Get an Answer ASAP!
Hello, I am Jose Sebastian. Your mechanic automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.
how many miles ago was the last service or maintenance you did to your vehicle? Thanks.
It was a correct procedure, now how is your car going? is it working well after the reset?
Dear customer, i apologize for the delay, it have been a little hard to understand your inquiry given the research made by you, you may have confused in several things, first clarify me some doubts, 1) what happens when you try reverse, example, the box not apply reverse, applies very little, apply for a moment. Anyway, could you explain me better what does the vehicle when you try to go back. 2) what have you tried so far?, for example, did you scan your vehicle first? Did you check the connections? the viscosity in the oil, the TCM etc.3) does the car only have problems when you put R or even when you use the other gears?Thank you very much.
Dear customer, did the problem start when you change the oil? All what you said indicate me problems in the gearbox solenoids body specifically in the reverse gear but the damage could get to affect all of them.
Dear customer, I recommend you to perform a reset and programming to the TCM (Transmission control module) with an automotive diagnostic equipment that has the Peugeot software. Observe the error codes to take into account which sensors or selenoids are being affected, delete them and reprogram the TCM.If the problem persist, with the error codes that we observe, proceed to check the wires first, to find out if you are having defects in broken cables, worn connectors or dirt plugs.
Finally, check internally the solenoids or valves body, to see which is the reason that is causing the failure and if it is necessary to replace it.
Dear customer, reading your questions and comments, I noticed that although I do not know if you have mechanic knowledge or not, you are not out of place in the diagnostics you are doing yourself, the Peugeot software is difficult to find with generic scanners capable enough to perform a remapping or a factory programming.For example I have worked with the launch specifically with the master x431, but perform this procedure with this scanner is not possible, Although, it is possible to analyze the live values and error codes in record(history), the equipment that you have, i do not know it with precision. Regarding to the error code that is being generated seems to me a very a very smart way on your part to cause the ECU to throw it at you doing the procedure that you have done, but I truly considered that the programming in your case will not will be enough to solve your problem, in the main dealers when we observe problems related to the error code you have and referring codes to the solenoids body, we proceed to replace all the solenoids body, it is a really delicate piece, and sometimes (extreme cases) we proceed to replace the entire transmission, so if you go to a Peugeot garage, you should not be amazed, if the diagnosis is the diagnosis they give you is to replace the transmission. what I can recommend you is that you should not agree with a single opinion, but you seek several opinions before doing the repair work.
My goal is to give you the best advice I can and I hope that I've helped today. It have been a pleasure to talk with you because you are a really clever person and i know your problem will be solved easily and although you have enough knowledge to do not let any mechanic to give you a poor diagnostic.Please remember to rate my service by selecting from the 5 stars at the top of the screen before you leave.
