    Question Questions about A/T

    So my transmission has been acting up for a few weeks, and I am not sure what to think of it. During light acceleration the shifts from 1st to 2nd and 2nd to 3rd seem to hesitate. I know BMW doesnt change transmission fluid so I dont know what to think. I did have a transmission fluid leak earlier this year, I didnt loose too much though. If they didnt put more fluid in when they fixed the leak could that be the cause of the problem?
    I stopped worrying about it for a while until today when I used my BT cable to scan for codes, this is what I got:

    Gear lever (GWS) Current Fault Codes 024B:
    Gearbox control unit

    Electronic power steering Current Fault Codes 024B:

    Dynamic stability control DXC8 Plus - E90 Current Fault Codes

    Longitudinal dynamic management Current Fault Codes 025D:

    Transmission distribution module Current Fault Codes 025D:

    I found all this pretty strange. I cant find where anyone has ever talked about these codes. Any help would be appreciated.

    Normally for anything transmission related if under warranty I suggest just taking it in. The transmission control module may just need an update, etc.

    Is that what those codes imply? I figure you have seen the majority of codes.

    Thanks!

    It seems to have gone away? This is very strange, it has been happening for a while. Im not really sure what to think, I am going to wait it out a bit longer before taking it in.

    If they never cleared the codes from the dealer or you had a low battery it could have triggered faults. Id clear them and see if they come back with some driving..

    Update:
    I know this has nothing to do with the transmission, but I changed my oil and all the problems went away. Very weird.
