Turbo-Hydramatic or Turbo Hydra-Matic is the registered tradename for a family of automatic transmissions developed and produced by General Motors. These transmissions mate a three-element turbine torque converter to a Simpson planetary geartrain , providing three forward speeds plus reverse.
The 4L80-E uses two shift solenoids, initially called Shift Solenoid A and Shift Solenoid B; they were later changed to comply with OBD-II regulations to 1-2 shift solenoid and 2-3 shift solenoid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, four distinct gear ratios can be achieved.
Sprag clutches mitigate roughness when a shift requires a combination of bands to be released or actuated. GM's Turbo Hydra-Matic 350 and 400 transmissions utilized overrunning clutches in both the low and intermediate gears, allowing for fully progressive shifting with no "overlap".
Introduced in 1964, Turbo-Hydramatic use quickly spread across all GM divisions, and they became referred to simply as Hydramatics (like GM's original automatic of totally different design), except for the Super Turbine 400 model. By the 1970s, Turbo-Hydramatic variants had replaced all of GM's early automatic transmission designs. In Argentina ...
The shift from 1st to 2nd or 2nd to 3rd range was long and drawn-out, ending with a harsh shift. The reason for this was that three things were happening. Not only was the transmission shifting to a very much higher range ( 2.93 to 1.56, but it was also simultaneously emptying the fluid coupling and making a mechanical lock-up.
The basis of the Turboglide's unique abilities was its five-element torque converter.Most automatic transmissions have a three-element torque converter, consisting of an impeller (an engine-driven pump); a turbine that rotates with the flywheel; a transmission-driven turbine that receives the energy of the oil propelled by the impeller, and a stator that redirects the recirculating oil so that ...
