There are too many variations to try to keep these on the shelf. They also include all new friction clutches, bands, steel plates, soft parts, filter, modulator (if applicable), as well as hydraulic upgrades, bearings added at several thrust locations, and other modifications depending on power level.Īlthough we use the build levels and options below, each transmission is custom built for the application. Very streetable and very reliable.Īs with all Jake’s Performance transmissions, they start with a select core that is disassembled, the case is blasted clean, hot tanked, pressure washed, inspected, painted and prepped for reassembly.

These are designed to replace a daily driver TH400 behind a stock or near stock engine and have increased service life due to our hydraulic, mechanical, and lubrication upgrades. Our Stage I TH400’s are an upgraded build.
#CHEVY 400 TRANSMISSION MOD#
If you need a stout TH400 for your Mustang, Lightning, or other Mod Motor or SBF, BBF combo, give us a call. We prefer you call in before ordering so that we can help you select the transmission that best meets your needs. We have automatic shifting TH400’s in turbocharged applications approaching 1000 HP.
#CHEVY 400 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.
