Our Street King Transmissions Save You Time and Money, Getting You on The Road Faster
The typical enthusiast tends to be a Jack of all trades sort. They have dabbled in engine work, handled their fair share of brake and suspension projects, and have probably tackled some interior and wiring fun as well. Where things tend to get dicey for many is aft of the flexplate, the transmission and rear axle. Going inside either of these major components for performance updates or even a simple rebuild from a zillion miles of service usually requires special service tools, a manual full of steps and specs, and a hospital-clean like work area. We know many that have tried to rebuild their own transmission or swap out a rear gear only to have to do it again (or third time’s the charm) to get it right if it is ever right again at all.

Sometimes it is best to simply have your transmission rebuilt instead of investing in all the tools and materials to do it yourself, especially if it is a “one and done” proposition and you’re not planning to rebuild transmissions as a side gig or hobby. The problem with this is often finding a solid and reliable shop that will do the work they say they are going to do and in the timeframe you expect. Today these are far and few between, much like a traditional engine machine shop. We know your time is valuable and when you need a new transmission for a project, or to replace your tired original, having the ability to simply order one of our Street King automatic transmissions, with no core return required, is often the best option.

A Street Friendly Chevy TH350 Transmission That Supports Up To 450 HP
If you’re looking for a solid performing street transmission for your classic pickup, muscle car, or hot rod build, our Street King transmission lineup is the perfect solution to your needs. Our Chevy Turbo 350 transmission features all new internal wear components such as clutch discs, bands, thrust washers, seals, and more, along with valve body modifications for improved shift firmness. Externally, each Turbo 350 transmission includes a new adjustable vacuum modulator and chrome oil pan with drain plug, making future transmission oil changes easier. Note that our Chevy 350 transmission is built without an external kickdown cable connection, requiring manual downshifting to engage “passing gear” use. Every transmission goes through a 23-point inspection process on an Axiline transmission dyno before leaving the factory to confirm shifting ability, line pressures, and more so when it lands on your door step you know it’s ready to go.

Our Street King Chevy TH350 transmission uses the popular 9-inch tailshaft housing and 27-spline output shaft, making it a drop in replacement for most any Chevy application. We do offer a Buick/Olds/Pontiac (BOP) TH350 Street King transmission model as well. Simply select the torque converter that best suits your needs, add a transmission dipstick assembly, and you’ll be in business. Of course, if you are building a project from the ground up, you may also need a flexplate, transmission cooler lines, transmission cooler, torque converter fasteners and other items as well to complete your installation.

Built To Last with No Core Return Required

Nobody wants to deal with trying to drain an old transmission of fluid, crating it up, and having some trucking line pick it up when it is convenient for them and not for you. With our Street King transmissions there is no core required. Nothing to send back, no need to sit and wait for any refund, just unbox your freshly built Street King Chevy Turbo 350 transmission and get back to your project. This is especially helpful if you’re building from nothing and do not have a core Chevy 350 transmission to even send back! Rest easy knowing our Street King transmissions are built by hand using the best parts and backed by the manufacturer’s one year warranty. To sum it up, our Street King transmissions are a great value for your project needs and will provide many miles of trouble free driving.
