Help me please !!
Hi I need help please.......I have a BMW330d touring 02 Auto facelift model. Auto box failed, purchased a second one which we fitted .....changes up and down fine no problems at all but when under load it makes a roaring noise as though the exhaust is blowing......but its not it seems as if its coming from the torque converter which may under load be touching the housing ? .
We have taken the gearbox out again and thought we would change the torque converter for the old one but it will not fit !!! it has a slight difference on the spline and also the lugs are slightly different......
the original gearbox numbers are GM2GWZ, 96023319, P24, 0507672,7-511008.
Vin number WBAEL92020PA90340
the new gearbox numbers are 1GWG GM1423897,96041612,R05 24 ,0167808
vin number WBAEL92080PAA90052.
Whilst the gearbox numbers are not the same I have run them both through the OEM parts and they show that it is the right gearbox for the 330D and as I say it changes perfectly just this noise we are now at a loss as to what to do can any help me please !!!
