Crisp shifts at part throttle progressively getting firmer with throttle. They don’t shift brutally hard we are able to keep them reliable by using many of the features GM designed into them.

#Th400 transmission how to#
Many builders don’t know how to make the trans live with boost and still shift automatically, so they recommend a full manual valve body. We specialize in building TH400’s for forced induction street driven applications where the customer wants the comfort of retaining the automatic shifting features. We do stock rebuilds all the way up to 3000+ HP Pro-Mods. Our “stock” rebuild is strong enough for over 600 HP repeatedly yet functions like a stock transmission. Our TH400’s use exclusive proprietary parts that are only available in our builds as well as techniques that your normal transmission shop or builder is likely not aware of. We have extensive experience building the TH400 for all types of applications.
