Automatic transmissions[edit]
Early models[edit]
The GM Hydra-Matic was a success and installed in the majority of GM models by 1950. Through the 1950s, all makers were working on their own automatic transmission, with four more developed inside GM alone. All of GM's early automatic transmissions were replaced by variants of the Turbo-Hydramatic by the 1970s.
- 1940–1967 Hydra-Matic — Oldsmobile (now the trade name for all GM automatic transmissions)
- 1948–1963 Dynaflow — Buick
- 1950–1973 Powerglide — Chevrolet (also used by Pontiac and Holden)
- 1968-1971 Torquedrive- Chevrolet ( Camaro and Chevy II, Nova. Manually shifted on Column. )
- 1957–1961 Turboglide — Chevrolet (V8 models only, except Corvette)
- 1958–1959 Flightpitch — Buick
- 1961–1963 Dual Path Turbine Drive — Buick
- 1961–1964 Roto Hydramatic — Oldsmobile/Pontiac (also used by Holden)
- 1964–1969 Super Turbine 300 — Buick/Oldsmobile/Pontiac (Oldsmobile Jetaway)
- 1968–1969 Torquedrive — Chevrolet (manually column shifted 2 speed automatic, 6 cyl only)
- 1956-1964 4 speed Controlled coupling HydraMatic, also known as Cadillac 315 or P 315 HydraMatic, Oldsmobile Jetaway, Pontiac Super HydraMatic.
- TempestTorque, ( Pontiac) a two speed based on Powerglide, but having the added feature of ' Split Torque ' dividing the engine power between mechanical connection and the torque converter in high gear.
Turbo-Hydramatic[edit]
The Turbo-Hydramatic was used by all GM divisions, and formed the basis for the company's modern Hydramatic line. The basic rear-wheel drive Turbo-Hydramatic spawned two front-wheel drive variants, the transverseTurbo-Hydramatic 125, and the longitudinalTurbo-Hydramatic 425. A third variant was the light-duty rear wheel drive Turbo-Hydramatic 180 used in many European models.
- Heavy-duty rear wheel drive
- 1971–1994 3L80HD (heavy duty version of TH400)
- Medium-duty rear wheel drive
- 1964–1992 Super Turbine 400/TH400/3L80
- 1969–1986 TH350/TH350C/TH375B/TH250/TH250C
- 1972–1976 TH375 — Light duty version of TH400
- 1976–1987 TH200/TH200C
- 1981–1990 TH200-4R
- 1982–1993 TH700R4/4L60
- Light-duty rear wheel drive
- 1969–1998 TH180/TH180C/3L30 — 3-speed European/Asian model. Also manufactured and used by Holden as the Trimatic transmission.
- Transverse front wheel drive
- 1980–1999 TH125/TH125C/3T40 — 3-speed light-duty
- 1984–1994 TH440-T4/4T60 — 4-speed medium-duty
- Longitudinal front wheel drive
- 1966–1978 TH425 — 3-speed
- 1979–1981 TH325 — 3-speed
- 1982–1985 TH325-4L — 4-speed
Electronic Hydra-Matics[edit]
The next-generation transmissions, introduced in the early 1990s, were the electronic Hydra-Matics based on the Turbo-Hydramatic design. Most early electronic transmissions use the '-E' designator to differentiate them from their non-electronic cousins, but this has been dropped on transmissions with no mechanical version like the new GM 6L80 transmission.
Today, GM uses a simple naming scheme for their transmissions, with the 'Hydra-Matic' name used on most automatics across all divisions.

*This transmission is part of a joint-venture between General Motors and Ford Motor Company to split development of two transmissions, a longitudinal 10-speed and transverse 9-speed. Ford led the design of the 10-speed transmission, as well as filing the design patents for said transmission. According to an official report by the SAE (Society of Automotive Engineers) the design of the 10-speed gearbox is essentially all Ford, while GM was responsible for designing the 9-speed 9T transverse automatic gearbox. As part of their joint-venture, Ford will let GM use the 10-speed transmission with rights to modify and manufacture it for their own applications. In-exchange for Ford's 10-speed transmission, General Motors will let Ford use its 9-speed transmission for front-wheel drive applications; Ford ultimately declined use of the 9T.[2][3][4]
- Second-generation transverse (Front Wheel drive)
- 2008–present: 6T30/6T40/6T45 — 6-speed light-duty
- 2006–present: 6T70/6T75 — 6-speed medium-duty

Short-Throw Shifter
A B&M Short Throw Shifter is a direct, bolt-on, self-contained unit. When you buy a B&M Short Throw Shifter, along with the complete shifter unit, you get explicit installation instructions. Installation usually takes about 30 minutes with nothing more than ordinary hand tools.
A B&M Short Throw Shifter offers a dramatic improvement in shifting performance due in large part to reduced shifter travel, or 'shift throw'. Shift throw refers directly to actual physical travel of the shifter stick - thus affecting the time it takes to shift from one gear to another. In a performance situation, the additional seconds (or fractions of a second) a factory stock shifter takes to go from one gear to another can result in slower elapsed times - or just a sluggish feeling when driving around town. A B&M Short Throw Shifter eliminates that sluggish feeling in a daily driver, and gives the racer an extra edge. For the Alero, you want part #45156. This can be purchased at Speed Unlimited, AutoAnything, Summit Racing, and many other automotive outlets.
Flywheel
Fidanza
Fidanza aluminum flywheels are made from the highest quality 6061 T6 aluminum. The material is fantastic for strength, heat dissipation and of course reduction in weight. The friction surface we use is an incredibly strong 1050 steel. The plates are milled to meet our high specifications. A Fidanza flywheel can mate with any type of clutch material, including organic, kevlar, ceramic, metallic and sintered iron. We attach the friction surface with military grade aerospace fasteners. The ring gears we use are also made from 1050 steel and are heat treated for durability. The gears are heated then pressed on and secured with grade 8 button screws. We were the first to utilize a stepped dowel system in most of our flywheel applications. This doweling method ensures that once the pressure plate is installed the dowels cannot be removed because they become locked into place.
Applications:
SPEC flywheels are CNC manufactured at an unheard-of .001 tolerance, in an industry where the standard is .010. This precision manufacturing process ensures perfect balance and a perfectly flat bedding surface for the clutch disc, both of which also contribute to the ultimate in safety for competitive environments. All SPEC flywheels carry SFI certification. To allow for specific inertia needs, SPEC flywheels are made in high carbon billet steel and aircraft quality billet aluminum. The aluminum and most steel SPEC units are rebuildable and feature a replaceable steel friction plate that is made from a friction- enhancing steel metal specially formulated for optimum clutch bedding and holding power. The aluminum and steel materials provide a light and medium weight option for all types of racing. SPEC spends a lot of time and effort on research and development of optimum flywheel dimensions and weights for all types of driving and racing and can optimize your MOI (moment of inertia) to maximize your car's output and performance.

Shift Kit
The B&M ShiftPlus shift improver kit is one of the most bang for your buck modifications for your transmission. ShiftPlus simply recalibrates your transmission's hydraulic system electronically. The ShiftPlus shift firmness not only makes driving more fun and pleasurable, but slippage and heat are reduced - extending the life of your transmission! Anyone can install a B&M ShiftPlus in minutes with a few simple hand tools. This new design allows you to improve the transmission's shifting performance without removing the transmission pan or valve body. The B&M ShiftPlus electronically enhances shift quality and is adjustable. A simple flip of the switch allows the transmission to operate in the performance mode. Flip it back and you are back to stock! For the Alero, you want part #70380, which can be purchased by most performance automotive retailers, such as Car Customs or Summit Racing.
Limited Slip Differential
The main advantage of a limited slip differential is shown by considering the case of a standard (or 'open') differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely—the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, and thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use, such as driving in mud, off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the angular velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.
Team Green makes an LSD insert which is designed to distribute the torque/HP to each wheel evenly. The Team Green LSD has been used in many turbocharged, supercharged, and nitrous equipped cars, such as SpeedRacerZ's 420hp/350trq turbocharged LD9, the 550hp/450trq turbocharged Quad 4, TVR's turbocharged 2.2L Ecotec, John Lenko's supercharged and nitrous injected LD9, to name a few.
Will it save the transmission? No. Its sole purpose is to split the horsepower and torque evenly to the drive wheels. Wheel hop will destroy a differential, with or without an insert installed.

Transmission Mount
Using stiffer mounts than stock or even solid mounts will eliminate or reduce engine roll on acceleration and allow much more horsepower and torque to reach the ground.
Milzy Motorsports designs a more solid mount for the 4T45E/4T40E. This high-quality billet aluminum piece with Delron polyurethane bushing replaces the weak stock transmission mount to eliminate engine movement, resulting in less power and torque loss to the wheels, stiffer shifts, and a more solid feel for the car. Available in natural finish or polished. Mount comes with the necessary grade 10.9 longer bolts. This works on either automatic transmissions for the Alero as they both use the same mount.
Manufactures a tranny mount for the 4T45E/4T40E as well. Manufactured from billet aluminum with poly insert - direct bolt-on to prevent loss of torque due to engine drivetrain movement. Available here.
4-speed 4T45-E Automatic
The 'MN5' 4T45E is able to handle vehicles up to 4500 lb (2041 kg) GVWR. Final drive ratios include 3.63, 3.29, 3.05, and 3.91. This same transmission is used in the Saturn Vue Green Line hybrid vehicle with the addition of an auxiliary oil pump and hybrid-aware electronics. It is designed for 3.0–3.4 L engines producing up to 205 ft·lbf (278 N·m) of torque.
