Alright so im getting ready to take my transmission into the the shop and have a rebuild done. what they are already doing is they are adding a transgo shift kit, and a full rebuild. now in my future im planning on doing more engine mods (408 stroker) but i dont want to have to pay for the tranny again. so what all should i have them do while they are in there. i was thinking the shift kit. im not sure the differences between the shift kit and the sonnax sure cure could someone clarify that for me? anything else i should have them put it?

 

Go take a look at what PATC does to make their Viper series to get some ideas: http://www.transmissioncenter.net/dodge.htm

If you do an essentially stock rebuild with just a Sure Cure (or just a shift kit) and put a 408 in front of it you're going to pay for the transmission again, guaranteed.
