Drivers said the vehicles shudder and shake in higher gears, and hesitate and lurch in lower gears, even after repair attempts. They also accused GM of telling dealers to provide assurance that ...
The transmission is monitored and regulated by Audi's "Dynamic Regulating Programme" (DRP), [2] which tracks the driver's inputs (from how the driver applies the throttle pedal), [2] driving conditions, and engine load - to compute the optimal gear ratio for fuel efficiency or maximum performance, as mandated by the user.

The torque converter of the Corvair offered 2.6:1 reduction at stall, and improved car performance when engine speeds were below ~2000 rpm. When starting out in Drive range, low gear was automatically selected and the low band applied under pressure modulated by a vacuum modulator which sensed engine output and adjusted clutch and band apply ...
Unlike the AOD-E, Reverse, 1st, and 2nd gear ratios in the 4R70-W are numerically higher, giving the transmission a better mechanical advantage and, in turn, better take-off acceleration, better passing acceleration, slightly lower fuel consumption, and designed for better gearset strength; the 4th gear ratio in the 4R70-W is up 0.70:1 from 0.67:1.
From 1958-1968 many vehicle manufacturers continued to use the next GM automatic transmission fluid specification, the Type "A" Suffix "A" fluid, in their transmissions. In 1966, Chrysler began releasing their own automatic transmission fluid specifications; see Mopar ATF for more information. GM ATF was the same color as engine oil through 1967.
It was developed for light-duty use in longitudinal engine rear-wheel drive vehicles, replacing the similar TH180/3L30. The 4L30-E was used in many European and Japanese vehicles, including the BMW 3-and 5 Series, Isuzu Rodeo and its derivatives, and Opel Omega/Cadillac Catera. It was replaced by the 5-speed 5L40-E/5L50. The 4L30-E was built at ...
Newer vehicles like Fiesta and Puma use the newer 7-speed PowerShift, while others have reverted to a torque-converter automatic. Volvo Cars While P3 Volvo models using the EcoBoost engine in 1.6T derivatives are equipped with the 6-speed PowerShift, some older P3 platform cars feature the 6-speed PowerShift in 2.0T derivatives (Badged T3 (1.6T ...
