It became the automatic transmission of choice for enthusiasts everywhere due to its durability and simplicity. The Turbo 400 can easily handle work in a drag car, off-road truck, hot rod or custom car, and any vehicle needing a durable, reliable automatic transmission. It does not rely upon computer controls, and can be adapted to a wide range of configurations. Rebuilding the Turbo 400 is not particularly difficult, but it does require care and specific attention to details. The procedure and these critical details are all reviewed in depth between the covers of How to Rebuild \u0026amp; Modify GM Turbo 400 Transmissions. Includes removal of the transmission from a typical vehicle, complete teardown, inspection and step-by-step reassembly. Some tips and advice for those planning to use their Turbo 400s in high-performance applications are also included. Tools \u0026amp; Equipment Dial calipers are for measuring thickness or size. They also can be used to measure depth. A good pair is pretty much a mandatory item for transmission rebuilding because you need to measure the thickness of friction and steel plates when stacking clutch drums. Transmission Fundamentals TH400 transmissions use a gear-type oil pump. The inner gear is driven directly by the hub of the engine’s torque converter. Note that the outer gear is offset in the housing. This creates a chamber that moves oil and forces it out of the pump. Transmission Removal A safety strap or chain is used to keep the transmission from sliding off the transmission jack during removal and installation. Shift Kits The TransGo Shift Kit comes in a box with an organizer tray to keep all the components separate. They are grouped and bagged accordingly. It also comes with very specific instructions, which also include some additional information for setting up TH400s during transmission overhaul. Since the kit is “adjustable,” choose the correct course of action based on the application, and follow the directions to the last detail. TH400 Initial Assembly Lube both lower Torrington bearing sets with clean ATF before reassembly of the lower unit. Make sure they are installed correctly with the lips facing in the same direction and in the same location from which they were removed. TH400 Final Assembly This TH400 transmission build is now complete and ready for installation. The torque converter must be installed and fully seated into the oil pump prior to installing it into the vehicle. Transmission Installation The transmission is in place, strapped down, and ready to safely install in the vehicle. Remember to have all of your tools organized and at the ready, and proper safety equipment in place.\u003c\/p\u003e","brand":"SA Design","offers":[{"title":"Default Title","offer_id":47621389615289,"sku":"1934709204","price":32.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0793\/7871\/0713\/files\/712tDMGbFOL._AC_SL1500.jpg?v=1781883486","url":"https:\/\/www.bestbuybook.com\/products\/ht-rebuild-mod-gm-turbo-400-trans-workbench-how-to-series-by-cliff-ruggles","provider":"BestBuyBooks","version":"1.0","type":"link"}
