The Ultradrive is a 4 speed automatic transmission from Chrysler Corporation. It was produced starting in 1. It was originally paired primarily with the Mitsubishi 3. G7. 2 engine in vehicles with transverse engines. In 1. 99. 0, it was expanded to work with the Chrysler 3. V6 engines in Dodge CaravanGrand Caravan, Plymouth VoyagerGrand Voyager, Chrysler Town Country, Dodge Dynasty Chrysler New Yorker. The Ultradrive was produced at Kokomo Transmission in Kokomo, Indiana, a plant which still makes front wheel drive Chrysler automatic transmissions. HistoryeditThe Ultradrive was a significant technological advancement in transmission operation, one of the first electronically controlled automatics. It pioneered many now common features such as adaptive shifting, wherein the Electronic control unit optimizes shifting based on the driving style of the operator. It earned a reputation for being unreliable. While the Ultradrive transmission had numerous issues, reportedly due to being rushed into production, a common problem was not necessarily caused by a design flaw, but by poor labelling both owners manuals and transmission fluid dipsticks advocated the use of Dexron transmission fluid in the event the required fluid was not available. The transmissions were designed to use a special fluid Type 7. ATF3, now superseded by ATF4 and many owners reported failures from the use of Dexron, as well as temporary issues which were resolved when the proper fluid was added. There may also have been mistaken impressions of failure due to the limp home feature. When the computer sensed a problem, such as a sensor giving an inappropriate reading, a code would be stored in the cars computer and the transmission would default to second gear only, under transmission computer control, so that owners could still drive to a service location for diagnosis andor repairs. This could have caused perceptions of failure and premature replacement. A major drawback to the second gear only limp mode was, if second gear was the defective gear, the vehicle would not go forward at all. The torque converter measured 9. The transaxle was cooled through an oil to water heat exchanger in the collector tank on the radiator, andor a standard oil to air heat exchanger. There were no bands or mechanical holding devices ratios were supplied by five different clutch packs. This allowed the transmission to be lightweight and to use fewer moving parts than the three speed it replaced. The 4. TE transmission which directly replaced the Ultradrive had a similar design and could be considered an evolutionary change, but it included different valve bodies, solenoid packs, sensors, and other components to increase reliability. This line was also given a flash programmable TCM and, in 2. Autostick optioneditIn some applications, a driver could select a certain gear with an extra position on the stick. This was called Autostick and required the driver to press on the safety button on the selector stick and then the stick could be moved to the manual position, where side to side movements towards the and icons made it possible to manually engage the transmission sequentially through all 4 forward speeds, but the computer kept some supervision in order to limit maximum engine RPM or prevent too low a gear for the vehicle speed. This option was advantageous in certain driving conditions, like slippery roads or mountain driving. Technical informationeditThere are 4 different types of units. Julien Donkey Boy Torrent Vostfr Wikipedia there. The differences between the types are the bell housing bolt pattern and valve body assemblies. A6. TEeditThe 4. 1TE is a four speed transmission fitted on 1. DodgePlymouth vehicles with the 3. L 6. G7. 2V6. Applications include but are not limited to the Dodge CaravanGrand Caravan, Plymouth VoyagerGrand Voyager, Dodge Shadow, Chrysler Le. Baron and Chrysler Sebring 1. Applications The 4. AE is a variant of the 4. TE that was originally used for the all wheel drive variants of the minivans, and was also used for the Chrysler Pacifica from its 2. Applications Since 2. TE was replaced by a similar but cheaper and lighter 4. TE transmissions in cars equipped with inline four cylinder,or naturally aspirated engines. Applications A6. LEeditThe 4. LE was an upgraded version of the 4. TE modified for longitudinal engines. It debuted in 1. 99. LH cars. It is strengthened with a reworked final drive unit, barreled axle shafts, and upgraded clutch packs. The major modification to a N S drivetrain while maintaining front wheel drive was accomplished by adding a differential to the transmission case, which was driven by means of a transfer chain from the output shaft of the lowreverse clutch assembly at the rear of the transmission case. Applications The 4. LE was modified in 2. RLE, originally for the then new Jeep Liberty. It is a 4. 2LE transaxle, modified for use in rear wheel drive vehicles by removing the integral differential and transfer chain. Power flow exits the rear of the transmission. The case has also been modified. By design it has full electronic shift control with adaptive memory to learn the operators driving habits controlled by the vehicles Transmission Control Module TCM. Contained within the automatics torque converter is an Electronically Modulated Converter ClutchEMCC designed act as a shock absorber for harsh shifting. Gear Ratios for the 4. RLE 1st 2. 8. 02nd 1. Applications 4. 0TES4. TESeditThe 4. 0TES and 4. TES are upgraded replacement versions of the 4. TE, which were first introduced with the 2. Chrysler Sebring. The 4. 0TES is used with the 2. L GEMAI4 engine while the 4. TES is used with the 2. L EERV6. The difference between the TES and TE is the TES has a shallower bell housing, and the torque converter is more compact. This was done for the revised packaging of the 2. Sebrings engine compartment. The 4. 0TES and 4. TES are also known As VLP, Variable Line Pressure Transmissions. A pressure sensor and line pressure solenoid was added to the valve body in addition to the solenoid pack that bolts to the outside of the case. Applications The 6. TE is a six speed derivative of the 4. TE first introduced on 2. Chrysler Sebring models fitted with the 3. L EGJV6. Applications also include the Pacifica crossover 4. L, the RT Platform minivans 3. L 4. 0 L V6 also 2. L Diesel for Europe, and the Dodge Journey 3. L 3. 6. L. Applications ProblemseditMany problems with Chrysler automatic transmissions are started when the automatic transmission fluid or ATF is replaced or topped up with standard, more common fluids like DEXRON or MERCON type fluids. Chrysler transmissions need to use their own fluid, designated as ATF4 Synthetic type 9. Chrysler, not any other or any other plus an additive. If any quantity of other type of fluid is added to the transmission, a complete drain, flush and replacement with the correct ATF4 will be needed. When properly serviced periodic fluid and filter changes with the required ATF4 fluid, the transmission performs correctly. The most common problems shift stuck, limp mode, blocking problems with the Chrysler Ultradrive transmissions are poor shifting quality and sudden locks into second gear limp home mode caused by the transmission computer detecting problems with sensor data. Nine design changes were made in an attempt to fix clutch failure, and four were directed to excessive shifting on hills. After pressure from the US Center for Auto Safety,7 Consumer Reports, and others, Chrysler LLC promisedcitation needed to waive the 1. Ultradrives that could not be fixed US located cars only. Chrysler ran an unprecedented campaign to contact all American owners of cars with Ultradrives to find and fix problems.
