Long story short. Gave the slightly modded pissant sound a hit for 3ish hours whilst giving the Blue bastard a proper tub. Deadened battery, Local auto club jumped me and got started.alternator charging fine. RACQ drives off and and then there is this terrible rattle and (I mean terrible )from under the bonnet, Lift bonnet and check for oil and other nasties etc. Nothing? ZF 6 speed BF ,auto. Neutral gears rattles it's tits off, under load rattle almost stops in gear both forward and reverse also under throttle also diminishes in P and N It has been suggested that it could be the flex plate , ? Any suggestions ? seems like a tow job Thanks in advance
