    Hey guys
    I got check light for Transmission , and fult code SA 24 DTC p107177
    And SA 24 DTC p105594

    The transmission doesn't go up or down shift manual or auto mode
    Sometimes changes , but loses The power in 2.4.6

    Any idea can help please

    Volvo 2015 ,, 590k
    Update , I got this message from technical support

    Your fault code that you have is for split engagement system. There is 2 different internal reduction systems inside the transmission. There is a range and a split system. There are a few different fall backs for the split system. One big thing to check would be to make sure the trans does not have any air leaks when the truck is fully aired up. The splitter is all internal and is commanded on and off by the tcm which is mounting to the top of the control housing. There is multiple test to be ran with a pc in order to move the splitter to see if there is an issue with the position sensor, shift fork, range cone, seals for cylinder inside, and to perform the clutch and internal speed sensor fault. That really is the only way to fully diagnose this fault code. Please let me know if you have any follow up questions on this. Thank you

    I shifts can only be repaired by the Volvo dealership. You might be able to find a non dealership shop but the I shift would need reprogramming and I would not trust another shop. Take it in and see what it needs unfortunately that is the only choice in the matter really.

    Take it to the dealer and bend over, most European vehicles are made this way I myself will never own one.

    I would disconnect power to everything big switch behind step door driver side (battery) area... let it sit for at least an hour. It might reset but it has limp mode but also warranty is good.

    Call dealer asap.
    If you keep driving it ,they might void any warranty you have.

    You have probably a top cover problem or an internal harness problem both require the trans to come down very few shops have capability to work on ishift if you are anywhere near chicago i can take care of it for you. without opening the trans it could be best case scenario $2000 with parts and labor or worst $7000 if something is wrong and i have put on a shortie trans from volvo.

    Trust me the man knows his sh*& when it comes to Ishift. I send my Ishift customers to him and he yells at me to fix them myself,with his guidance if I need it. LOL!! I think I trust him more than myself.
