ATSG - CHRYSLER - DODGE - 62TE .pdf

The new 62TE transaxle by the Chrysler Group is fitted behind a 3.5L V6 engine in the Avenger, Sebring and Sebring Convertibles (JS Body), the 4.0L V6 engines in Pacifica (CS Body) and the 3.3L, 3.8L, 4.0L Caravan and Grand Caravan vehicles. It has 6 forward speeds with a 7th forward gear used in a specific downshift sequence known as the “4th prime". Fourth prime ratio is 1.573:1 which is a ratio between third gear (2.284:1) and fourth gear (1:452:1). Refer to the Component Application Chart. Fourth prime is used for a smoother highway speed kickdown from sixth gear and to provide a better ratio for climbing grades under certain conditions. This transaxle has another technical first for Chrysler in that this transaxle introduces the "double-swap" shifts on the 2-3, 3-2 and 4-2 shifts. This occurs when two components are turned off while two different components are turned on. This clutch to clutch syncronization takes place within 40-70 milliseconds, producing a very smooth shift. To avoid a "Double-Swap" shift on a 6-4 downshift, the transaxle shifts into "4th Prime" instead of 4th gear, which requires only the OD clutch to be turned off and simultaneous application of the UD clutch. A freewheel device (sprag) is used to assist in smoother shifts with its nonsynchronous application and release properties. The sprag holds in first, third and fourth assisting in smoother 1-2, 2-1, 4-5 and 5-4 shifts.
