hi i am new to this site and would really appreciate any genuine advice that you may have to offer.
I have a 93 bmw e36 325 auto that has recently developed a constant noise that is only present when driving (with transmission hot or cold) and gets loulder as you increase speed it normally starts at about 30mph and does not affect the drive or selection of gears which is faultless.
i think it is possibly from the transmission as the noise seems to be coming from the gear selector area the noise is best described as very similar to putting a peice of card on a push bike wheel however the noise can only be heard inside the vehicle.
before now this noise has been a minor irritation until today when there was one lould bang and the noise got loulder and now starts at 10mph there is still no difference in the drive etc...
thanks in advance for any help
