Hello again all OK...well last week by tranny took a dump..had it sent to the shop and turned out to be it overheated etc... well it got all sorted and at the same time they changed the rear main seal (i had a leak which was annoying for a good while) and also installed a engine mount ive been putting off and some other lil things.. car is running fine BUT what ive noticed (ive had the car back for only a day) is when i accelerate theres a very slight whirring sound that increases as you go faster.. what could that be??i still have a year warranty so im not scared but am curious as to what that sound could be??vacuum leak from a hose not ont ight or mayb or a belt or what?? just fishing for ideas.. cheers all
