Re: Are special tunes needed for a 99 with a built transmission?
Avoid a tune that boosts up the line pressure. Most generic tunes do that. That job is done in the valve body of most "built" transmissions. (if correctly built that is). FYI. I still have my BTS transmission that was installed in 2004 about a 180,000 miles ago and it is still as good as the day Brian (BTS) installed it. He told me about transmission tunes and to avoid them with his valve bodies. He knows a little bit about that stuff!
