Was out last evening enjoying the familiar growl between 4-5000 revs when BANG - Alfetta popped out of gear. Never done this before. Used to rattle a bit at 4500 but now really rattles. Goes OK but worried I've bust something. Any ideas - wonder if I've goosed a transaxle mount...
mmm, difficult to tell if it doesnt do it under load, but I would be very surprised if you have managed to break the diff on a standard set up, they are tough as nails. if its only doing it under load it could still be a donut or gearbox rear/front mount.
When under load and it starts vibrating, dip the clutch and see if it goes away. if it does, then at least you know your issue is on the gearbox, diff or clutch assembly.
Been out on the road - vibration starts at 3500. Put in clutch and vibration continued so guess its the propshaft now. Rear two donuts look OK - need to get underneath to check out the front. Gingerly driving to work tomorrow - is this wise?
