HEY GUYS, i have a 1988 austin mini cooper, with 1275cc motor, with hardy spicer type shafts and tranny. Since i installed motor and tranny, i am getting LOUD HUMMING NOISE from what seems to be tranny, i took motor and tranny out, changed every BIG BEARING in the tranny, put it back together and still loud hummin noise. When i depress my clutch it stops,release bearing has been changed also.
seems its worst when , i accelerate or decelerate, ANY IDEAS??
