Switching between automatic and manual transmission modes is by moving the shift lever to the bottom that then allows upshifts and downshifts by moving the lever left and right. [9] The system works with shifter down into a gated area on the shift assembly that allows the shifter to be pushed to the right (up-shift) or to the left (down-shift ...
The turbocharged EDV/EDT was initially developed for the PT Cruiser GT as a way to add power, and is similar to the regular EDZ. As the PT Cruiser was based on the Neon platform, PVO engineers were able to take the EDV/EDT and make it work with minor non-costly changes for the SRT-4.
Powershifting, also known as full-throttle shifting or flat-shifting, is a method of gear shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike during a normal gear change, in a powershift the driver does not let off the accelerator.
The 2000 PT Cruiser grew out of a collaboration with Robert A. Lutz, who was an executive at Chrysler at the time, Dr. Clotaire Rapaille, and Bryan Nesbitt. [21] Nesbitt later went on to design the Chevrolet HHR. The PT Cruiser's design was loosely inspired by the Chrysler Pronto Cruizer concept car while recalling the Chrysler and Desoto Airflow.
Float shifting can reduce clutch wear because it is used so much less (only for starting from a standstill). Conversely, improper engagement of a gear (when the engine and transmission speeds aren't matched) can cause wear on the synchros and lockouts, and damage the gears by physically grinding them together due to a difference in speed.
When shifting, however, depressing the clutch is required. This disconnects the engine from the wheels, and the engine speed is no longer linked to that of the wheels. When upshifting, this is usually not a problem, as the tendency of the engine to reduce speed itself without gas will slow it to loosely match the lower speed of the higher gear.
Power and torque curves for two example car engines. Since the torque and power output of an internal combustion engine varies with its rpm, automobiles powered by ICEs require multiple gear ratios to keep the engine within its power band to produce optimal power, fuel efficiency, and smooth operation. Multiple gear ratios are also needed to ...
The clutch brake not only slows or stops the idle gear axis but can also prevent shifting into gear until the clutch pedal is released a few centimetres (or inches) off the floor. In order to shift into gear, the clutch must be halfway off the floor, otherwise, the clutch brake will prevent the transmission from being shifted into or out of gear.
