Turbo transmission a search-

The members of automatic transmissions by General Motors, 350 Turbo Transmission are a turbo hydromatic with 3 speed longitudinal transmission. The Turbo Hydra-matic 350 first used in 1969 model cars developed jointly by Buick and Chevrolet to replace the two-speed Super Turbine 300 and aluminium-case Powerglide transmissions. So, although it carries the Turbo Hydra-matic name, the Hydra-matic Division of General Motors had nothing much to do with its design.

The key buyers can be categorized as drag racers and car enthusiast, for the power it consists. Engineered to Dominate, the Turbo 350 4×4 SS Mega Monster transmission is tough enough to withstand the rigors of even the toughest street machines delivering tire-spinning shifts race after race. It is ideal for vehicles powered by engines producing up to 550 horsepower with a non-supercharged system using pump gasoline. Equipped with a Manual/Automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears giving you all the right to say “Eat My Shift!”. When you use the manual gear selection feature, the Mega Monster up shifts and downshifts when you move the shift lever. When you select the normal drive position, the transmission retains its firmness; automatically shifts for the ease which you look for in an automatic transmission. The Turbo 350 is a 3-speed automatic transmission

350 Turbo TransmissionHow can turbo 350 be rebuilt:

There was a 350 Turbo Transmission that could be used on 6 cylinders and the 350 turbo that was used on 8 cylinder engines. To upgrade one was simply buying a kit and making the modifications. The transmission needed to be able to handle the extra power so minor parts were swapped internally. Basically the difference is rings, springs and other goodies inside the transmission

Before you get started rebuilding your transmission, you’ll need a few parts and tools by your side, handy. You’ll need the appropriate transmission rebuild kit for your Turbo 350. Depending on what type of kit you buy, it should come with at least new steels and frictions. Usually included are all the bands, clutches, seals, sealing rings, gaskets and a filter and drain plug. Most  higher end rebuild kits will include a new shift kit as well. An automatic transmission shift kit is only needed if you want the gears to shift sooner, but it can also reduce transmission wear by reducing or eliminating shift overlap. The better kits will also include new valves and valve springs for the valve body.

A transmission repair manual is a must. We recommend one for your specific model from ATSG (Automatic Transmission Service Group). Every automatic transmission will need a universal clutch spring compressor as well as snap ring pliers and pic sets for removing valve guides.

Of course you will need to remove the transmission from the motor and chassis. If you’re not familiar with this, the first part of the Basic Engine Building, video is easily available on internet. All of the automatic transmissions rebuilding video’s out there start off with the transmission already out. So be aware if you aren’t familiar with removing the transmission. You will also need a good work space and transmission stand. It’s best to have it able to rotate around for removing and installing components.

When rebuilding a TH350 transmission of any year or model, you can remove all of the internal parts down to the low/reverse piston without removing the valve body. It can be removed separately once it’s internal parts are removed.

As you disassemble your transmission, make note of any obvious wear to parts that may need replacing. Keep the internal parts in the order they were removed to keep track of everything. Thus with rebuilding one can easily understand the understanding, usefulness and drawbacks of 350 turbo transmission.
