Finally after about 10k of lock up slipping and sloppy shifts, we dropped of our Tahoe for a transmission overhaul. It had the issue with the tcc from the valve body being worn (only 119k on it) can wait to get it back already. Next on the list is deleting DOD new cam package and a tune
Has anyone ran into this problem with the worn out valve bore? Cost to fix and was trans fine after? I've gotten a few quotes from 300-600$ it's been acting up for about 5k miles but is more noticable now with the exhaust on the truck. Edit: truck is a 07 Tahoe 4x4 if that matters just turned 116k
