Turbo 350 transmission and turbo 400 transmissions are GM transmissions found in 1969-1979 models. 

Turbo 350 transmission

• The Turbo 350 transmission is a three-speed automatic transmission. 
• It is called Hydramatic 350 that made its debut in 1969. 
• It was a joint Chevrolet and Buick project.
• It was built to replace the Super Turbine 300 Power glide automatic. 
• Spawned similar to the other GM transmissions like 250, 250c, 350c and 375b.
  

Turbo 400 transmission

• Three-speed automatic transmission.
• It first appeared in 1964 Buick and Cadillac.
• It was called Super Turbine 400.
• 1965, Oldsmobile, Chevrolet and Pontiacs featured Turbo 400 transmission. 
• It could be distinguished from Turbo 350 transmission from its Texas-shaped oil pan.
  

• The Turbo 350 transmission has a first gear ratio of 2.52 -1.00; the second gear ratio of 1.52-1.00; the third gear ratio is a direct drive. The reverse gear ratio is 2.07-1.00.
• The Turbo 400 transmission has a first gear ratio of 2.48-1.00; a second gear ratio1.48-1.00; the third gear is a direct drive. In the reverse, the gear ratio is 2.07-1.00. 
• In both Turbo 350 transmission and Turbo 400 transmission, the torque convertors are the same along with many other components. A lock-up torque converter was added in the 1980s but was removed for inconsistent acceleration.
• The Turbo 400 transmission gained more popularity as it was a great choice for four-wheel drives. Its 3/4inch and 1ton GM pickup were preferred even by Ferrari for its ability to handle high torque. 
• Handling horsepower up to 500 and managing 4,56 axle gear ratios with 13,000-lb. towing capacity. 
• With the advent of smaller engines from 1973-1978, owing to the shortage of gasoline, Hydramatic 700R4 and 200-4R passengers from Chevy and GMC replaced Turbo 400 transmissions in passenger cars and pickup trucks. The last Turbo 400 transmissions were manufactured in 1986. It was renamed 3L80. The Turbo 350 transmission faded out in 1984.

Turbo Transmission for Sale

 

Turbo-transmissions is a hydrodynamic link converting the mechanical energy of the motor into the kinetic energy of the fluid. This happens through the torque converter and the fluid coupling before the final rotary output is produced. The fluid passes through rotor blade canals. The flow rate is high at low pressure. This is how a turbo transmission differs from a hydrostatic transmission.

How does it work?

• The torque converter is the main unit of the turbo transmission.
• This mechanism is in high demand in diesel-powered vehicles. 
• It shows a better startup performance, without affecting the dimension of the startup convertor and constant in transit loading of the travel phase converter. 
• The single-stage converter using centrifugal flow turbine is the best amongst many different torque designs. Owing to its simple construction and radial stability of the turbine the convertor is well adapted to rpm operations. 

In the 1970s the enhanced traction features were coming closer to the startup traction, the two-convertor transmission replaced the three-converter transmission. The quest for improving the torque convertors is continuous though they are quite advanced now. 

Engineers are better informed of modern computational fluid dynamics (CFD) which gives them a clearer picture of rotating turbine wheel flow patterns at each grid intersection. It helps to calculate the flow volume, speed, and pressure.

Difference between normally aspirated transmission and turbo transmission

• The normally aspirated transmission and Turbo transmission can be both 5-speed transmission models with the same splines on input and out shafts. 
• The housing of both the normally aspirated transmission and turbo transmission is mostly the same. 
• The spot where the starter mounts on the bellhousing is machined differently engaging the slightly larger diameter flywheel which prevents the flywheel teeth from scraping the inside of the bellhousing. 
• A normally aspirated transmission 5 speed can be used in a turbo transmission with the use of a flat washer to make the turbo transmission flywheel fit well. 
  

Difference between transmission turbo 350 and turbo 400

• The turbo transmission is a hydrodynamic, multistage assembly drive that works on the principle of fluid dynamics. 
• It includes torque converters, fluid converters and optional hydrodynamic retarders. 
• This low torque transmission turbo 350 and turbo 400 are GM transmissions used from 1969 to 1990 in heavy vehicles.
• In light cars, a modified TH-350 was used as a high torque transmission. 
• The TH 400 used in heavy cars operates on high torque and is a stronger transmission than 400. 
• The TH 400 is placed on the right rear of the transmission.
• A kick-down cable differentiated the TH 350 from the TH 400. 
• They were used in Chevrolet V-8 cars and light trucks.
• Both transmission pans have 13 bolts but with different shapes. 
• A square pan cut from the corner distinguishes a TH-350 while a TH-400, uses an oblong-shaped pan and the pan sides have a hump, curved at one and straight on the other side. It is further identifiable with two circular indents on the humped side of the pan.
• The TH-400 measures 38 inches in length while the total length of TH-350 is 33 5/8 inches, this is when both use the longest available tail shafts. The body of the TH 400 measures 25 inches while the TH 350 is 21 5/8 inches. 
• The TH-350 tail shafts are 6-, 9- or 12-inch long.
• The TH-400 tail shafts are 4-,9- or 13-inch long.

Why Is the Transmission So Important?

Why is the Transmission so Important? 

The transmission is an important automobile component. It transfers power from the engine to the driveshaft and the rear wheels or the axle half shaft and front wheels depending on the vehicle. Vehicles have an automatic or manual transmission. In stick shift vehicles, drivers need to control the stick to operate the vehicle. 

How does the transmission work? 

The transmission combines the gearsets with a torque or fluid coupling converter. The torque converter connects the engine to the transmission and uses pressurized fluid to transfer power to the gears. When the vehicle stops the transmission disconnects the engine from the drive wheels.  The transmission gradually runs the engine from stop position to motion with ease until the vehicle takes on a steady speed. 

Manual Transmissions

These have a clutch pedal and a shifter that the driver uses to change gears manually. The driver must know when and which gear to use by controlling the clutch. This transmission involves the flywheel, pressure plate and clutches to connect the engine with the transmission. 

The transmission is connected to the engine via a flywheel, pressure plate and a clutch. Each time a gear has shifted the clutch is pushed. 

Manual transmissions come in various types: 

Dual-Clutch

• Uses two separate clutches for even (2, 4, 6) and odd (1,3,5 and reverse) gears. 
• Common in older and race cars. Today’s cars have automated double transmissions with computer controls that adjust the gear shifting process and ease manual gear changing. 

Unsynchronized

These strong transmissions wereused by trucks in the 1960s. Unsynchronized transmissions also called rock crushers as the drivers grind the gears together getting them to mesh. 

Synchronized/Constant Mesh

The cluster gear, drive gear and mainshaft gears move constantly. The transmission uses pads to slow the gear down. You do not need a double-clutching action in this. 

Automated  

A transmission with computer-controlled shifting and a clutch is also called ATM.  It is a manual transmission used in heavy-duty trucks.

Single-Clutch

A single clutch manual transmission with the shift and clutch is controlled by a computer or electric hydraulic or electrohydraulic. Dual clutches took over these with a capacity to handle more torque. 

Automatic Transmissions

Processing the power, they do not use the clutch and rely on the torque convertor to switch gears. However, most SUVs and trucks use traditional automatic transmissions. The following components make an automatic transmission. 

Direct-shift gearbox: This gearbox has two clutches that disconnect alternatively, provides smooth acceleration and fast shifting. 

Tiptronic: This gearbox allows manual shifting of the automatic transmission, through the shifter or steering wheel controls. If the transmission is outside the parameters, then the computer will not allow the manual mode. 

Hydraulic: The fluid pressure present inside the automatic transmission.

Electric cars

These use Single-gear systems, have compact single-speed transmissions that transfer power to the drive wheel. It can be combined with the motor or bolt-on

CVT Transmissions

A pulley-based continuously variable transmission (CVT) is used in small vehicles with small engines and used in a snow machine. These are also popular in hybrid vehicles. It uses a primary small drive and a secondary large driven clutch connecting the two with a belt or chain.

 

When to replace the transmission?  

Automatic transmissions fail between 80,000 and 150,000 miles. 

Manual transmissions can fail sooner at 80,000 miles.

• Problems in shifting gears and your vehicle jerks or shakes
• Strange sounds coming from your engine when you shift gears.
• Excessive friction causes the transmission fluid to burn.
• Blot fluid on a paper towel to check leakage.
• Transmission fluid has a reddish or orange color, dark reddish or dark orange suggests dirt buildup.

Why should you buy a used transmission? 

• Used transmission on sale is 80% cheaper than original transmission.
• You can find a transmission that is identical to a new one.
