Th-400 Build questions.
Th-400 Build questions. I am in the process of building a TH-400 for my built LS1 nitrous engine. (300 shot max) I have been doing a lot of reading and research on th400 builds. My plans it right now include: 4l80e drum, 34 element upgrade, rear case bearing upgrade, and dual feed feed mod for the direct drum. I am looking at using a Hughes auto/manual valve body. I have been building ford transmissions for a while (I work at a ford dealership) so i know my ins and outs on them, What other mods or upgrades, ones I can do myself or purchase, would be a good idea for a the TH400. Car will be street driven to the track and around town some, so kinda iffy on a trans brake from what I've been told/read. Thanks in advance for any input/advice.
