my 2004 530i is sick.... my tranny is a problem and i have no get up power, i have to gradually get up speed on the hwy, i've tried the gas pedal to the floor for 30 sec. some luck for a few days but back to normal. i just went to the dealer and had a tranny software update $190.00 ouch!!! i changed the tranny fluid and pan.. all i ever get is the /transmission /malfunction symbol if i step on the gas suddenly or to fast, i went to the dealer today andthey said i have a tranny leack and i need a " Mechatronic Sleeve " $625.00 job........... any suggestions??????? will this Mechatronic sleeve give me my car back????????????

 

Hey another issue i was having with my 2004 530i auto it started throwing codes about the O2 sensors, cam shaft sensors, banks were to lean, coils 1-6 were bad, spark plugs and MTF were bad, so week i was replacing these items and the codes would still come back, well several thousands later i found a BMW driver at a gas station and we talked about my issues and he laughed and said he went through the same thing. come to find out it was the Manifold adjuster unit... so i bought one of those and when the old one was pulled out WaLa... theres a lil flap on it that opens and closes and it was broke in half and could not open and close, we put the new on in and all the codes went away. now if i could get my tranny squared away...

 

DISA valve failure, pretty common. Mechatronic sealing sleeve leak is also pretty common; too bad it wasn't done when the pan and fluid were replaced. not sure how bad your leak is or if it's going to cure your problem, but it should be replaced if it's leaking. find a good indy in your area, i'm sure they'd do it for less that what the dealer is quoting. BTW, did you refill the transmission with the correct fluid?

 

i dont know how much fluid that ive lost
