How much does a Hydra-Matic transmission weigh?

How much does a Hydra-Matic transmission weigh?

There were two models of the Roto Hydramatic: the lightweight Model 5, which weighed 145 lb (66 kg) and had ratios of 3.03, 1.58, and 1.00, and the larger Model 10, which weighed 154 lb (70 kg) and had ratios of 3.50, 2.93, 1.56, and 1.00.

Is the Hydra-Matic transmission good?

Hydra-Matic was a complex design that was expensive to produce. Despite some early problems, it was reliable and so rugged it was widely used in drag racing during the 1960s. It was not as smooth as some competitor’s transmissions (notably Buick’s Dynaflow), but was more efficient, especially at highway speeds.

Do automatic transmissions weigh more?

Automatic transmissions are typically heavier than manual or stick shift transmissions. Manual or stick shift transmissions are typically lighter weight than automatic transmissions.

How does Hydra Matic transmission work?

The hydramatic drive does not have a clutch pedal to engage and disengage the transmission system from the engine. The motion of the vehicle is controlled entirely by the accelerator and brake. The hydramatic drive combines a four-speed forward and reverses automatic geared transmission with a fluid flywheel.

Who makes the most reliable transmission?

Lexus and Toyota — which rely on older transmissions in many of their models — were the best-performing brands in the survey. Lexus or Toyota has topped the survey since 2011. Audi, Mazda and Subaru rounded out the top five. The worst performers were Infiniti, Cadillac, Ram, Jeep and Fiat among 28 brands.

When did the Hydra Matic transmission come out?

The development and early history of GM’s pioneering Hydra-Matic transmission, introduced in 1940 by Oldsmobile. Cars by Type Cars by Era Cars by Brand Technology & Terminology

What to do if your Hydramatic transmission is stuck?

If the throttle valve is stuck, or sticky, there is contamination in the valve body. In most cases, the transmission should be removed, disassembled, inspected, and repaired. Transmissions that succeed the original Hydramatic design also use a detent or kick-down device. The original Hydramatic did not use a detent.

What is the detent cable for Hydramatic shift?

The detent may be an electrical connection and electric kick down solenoid (THM-400) or a detent cable (THM-350). The THM-200 uses a throttle valve cable and also serves as the detent (no modulator).

What did the throttle valve do on a GM Hydra Matic?

The throttle valve gave the driver some ability to either hasten or delay gear changes, but not to override them. Therefore, you couldn’t hold a lower gear past redline, deliberately lug the engine in high gear under load, or force a downshift that would over-rev the engine.
