i have a problem with my gearbox, yesterday i crunched it in 3rd gear like nearly 10 times. mostly on downshift but it has also happened when goin up gears aswell. it would crunch big time b4 getting into gear. this is when shifting normally, i've tried putting into 3rd very slowly and it goes in nice all the time but annoyin. i've crunched it once or twice b4 but thought i did somethin wrong but now i know its not me.
i have an aw11, and my gearbox is lsd. i didnt know what oil to put in there but i saw it had atf previouly so just continue to use atf and been driving it for bout month now. could this be the problem? i heard people on US mr2 forum use redline mt90 but i dunno where to buy it, will this fix the problem?
say worst comes to worst how much will it cost to fix? or are these gearbox redily available second hand to buy?
