The AOD in my 89 LX 5.0 is dying. What other automatic choices do I have? I'd like something that can handle extra power, but still be good for cruising around (which is the majority of what I do in it....it's a convertible ). Is the crappy AOD my only option? Would hate to rebuild a tranny I don't like in the first place. Help!! I'm new to all this and hoping someone has been through this before. Thanks.
