I have a 2005 GMC Savana 2500 and have to have my 4th flexplate installed Before 90K miles. GMC and the dealership told me to Pound sand and they will not honor any warrenty or resposibility. I know this isn,t normal as I am not an idiot and used to build motors and trans on occation in my younger Days. I was thinking of ordering a beefyer plate fron jegs or summit but want some feedback from the guys who know ( that would be you) The truck has the 4.8 L but not sure how to find out what the trans is. Any help will be appriciated. I don,t want to do this myself but have a feeling I will have to. Does the trans need to be bulled out or can I slide the plate up from the bottom and bolt it on without pulling the trans? Thanks for your input.
