My tranny is starting to slip at 104000 miles. I'm wondering if I should just go ahead and buy a used 4t65e hd tranny and build it myself (have taken a couple tranny's apart and put back together) and put the necessary parts in so I can run a zzp turbo setup later or I just buy a upgraded tranny. Money is a factor. What parts can I just do myself and what should I send out to get done
Its not like my tranny is going to go any day now but I rather start building one now than later.
