From my past experiaces w/ an AOD..(3 in 6 years on a mid-14 car)
I seriously advise you to consider a t-5 or c-4 swap....
I wish i did the first time...AOD parts are extremely expensive...sun gears are about $250
converters are $400-$500
clutch packs are about $200
you will have at minimum a $1000 bill IF you do the rebuild yourself.
more like 2 grand if you take it in...and it will brake again,very soon.
