DIY TH400 rebuild yes you can. Part 1

http://www.crankshaftcoalition.com/wi... Rebuilding a TH400 for High Performance! 👍 Rebuilding my craigslist score that wasn't a fresh rebuild as advertised. Parts inspection, upgrade if needed to the 34 element sprag, dual feed the clutches, manual control of the 1-2 shift. Dive in and get familiar with “Modules” inside the case. You’ll understand that you’re doing several small manageable projects not one Big one! Step by step!!! 👍
