Yeah, I know about the basics. I've got 4 cars at the house. I do all the maintenance on them. Since u'all know "that 4.5 and that particular transmission" so well, figured u'all could short list me on the things that have to be addressed at 150,000 miles on those particular models. U know, the things that usually require rebuilding or re-purchasing on 88's in general. I think someone mentioned it's a definite "yes" on rebuilding the tranny at that mileage.-Thanks.
