Transmission general data The 8-speed RWD automatic transmissions A8LR1, A8TR1 (4WD) with longitudinal positioning designed by Hyundai were installed on luxury cars with engines from V6 3.0 up to V8 5.0L since 2011. This transmission was launched in production in 2010 and after several years of testing on the Korean market, Hyundai engineers introduced some updates, which improved some hard parts and frictions. Some electrical mechanisms and computer settings were also changed.

Ravenol SP-IV RR fluid is used for these finely adjusted transmissions. Specialists do not recommend using other types of fluid, because the oil in this transmission performs many other functions in addition to lubrication, cooling and hydraulic environment. Although the oil ageing slightly worsens its qualities, after running 80-100 thousand kilometers it is recommended to check it for transparency and change it together with the filter-pan, especially if the transmission operated at maximum loads. One of the main soft spots causing problems in this transmission is the valve body with solenoids. This transmission is very sensitive to operation with contaminated oil under the condition of ultimate loads. Intensively operating VFS solenoids-electric-regulators are the first to reach the end of their lifespan.

Transmission general data 9 speed transverse ZF 9HP48 for the front drive was released in 2013 at two factories: in Saarbrücken for Europe and by Chrysler in Kokomo (USA) for Japanese and American cars - Honda and Chrysler. Both versions have significant differences in the range of spare parts and major components because Chrysler made plenty of changes in its version . It was tested on the American market and there were mostly problems with computer settings and electrics. ZF9HP48 is designed to transfer the torque from the engine up to 480 Nm, but as all transmissions with transverse positioning it is much less endurable to extreme stress and therefore it is installed on urban jeeps.9 gears are only required when the vehicle passes half a day at the 1st gear in urban traffic and when out of traffic it immediately gets on the freeway where the 9th gear serves to save fuel.

In this case the filter is replaced as well .Prolonged driving with contaminated oil and worn-out sealing rings leads to rapid wear of solenoids, which operate evenly as a group and also a group fail around the same time period. But it actually requires a long time to have the solenoids fully unconditional. ATF change is quite difficult and requires experience in automatic transmissions, especially with the 6-speed and 8-speed ZF automatics. Smell of burnt ATF or presence of metal grit of around 1mm is considered to be an indicator for a major overhaul of the automatic transmission even if the gearbox runs flawlessly.

In case of frequent “kickdown” usage with a switch-on of controlled slipping of the lock-up clutch, the wear-out of friction elements occurs quite rapidly and contaminates the valve body, fluid and filter. The filter is made of plastic with a two-layer felt membrane and its better to change this part in a timely manner. The oil and filter should be changed when there are any suspicions related to oil transparency. Such situations may occur after travelling 40 thousand kilometers or 80 thousand kilometers depending on driving style and adherance to the transmission warm-up rule before driving in winter time. Removal of the pan allow specialists to estimate the level of components wear-out and valve body contamination.

Transmission general data The 9-speed automatic transmission Hydra-Matic 9T50 for front-wheel drive vehicles was designed by GM and was officially showcased in December 2016. This transmission was intended to replace its 6-speed predecessor. According to GM engineers, the 9T50 transmission allows striking a balance between high dynamic parameters and fuel economy. The size of this transmission is the same as the size of its 6-speed predecessor, but the Hydra-Matic 9T50 also supports start/stop technology and has a new torque converter.

Transmission general data The 7DCL750 7-speed dual-clutch transmission was designed by Getrag for transaxle and mid-engine positioning in sports vehicles with RWD or AWD. The 7DCL750 has an optimal installation length, which became possible thanks to a 4-shaft structure. The ratio of 1-st gear, 7-th gear and final drive can be defined and adopted to the respective usage. This transmission also may have a mechanically or electronically-operated differential locking device. The dry-sump lubrication system helps to enhance the level of efficiency and fuel consumption.

It leads to the chain reaction of metal wear and further contamination of ATF. Thus, DSG transmissions are equipped with outside filters of high capacity. Getrag engineers recommend changing this filter more often, especially if the transmission is old.

Transmission general data The 7-speed automatic transmission PowerShift 7DCT300 was manufactured by Getrag. This transmission with 2 clutches is intended for front-wheel drive cars with the engine east-west mounting. The design of this transmission successfully combines two multiple-disc clutches and electro-hydraulic gearbox actuators. The 7DCT300 is designed on the basis of the 6-speed PowerShift 6DCT250. The basic design of the transmission is implemented according to the three shaft configuration. At the same time the total weight of the transmission was reduced from 72 to 67kg. The development of the improved design was made because of more severe requirements for fuel economy, dynamics and environmental compatibility of cars. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type7DCTRWD2,11,8DCTF105786 Designed on a modular platform, the 7DCT300 transmission is intended for engines with the torque capacity up to 300 Nm. Engineers of this transmission solution think that the most remarkable feature of this transmission is an intelligent power transmission system Smart Actuation. This system facilitated to reducing the powertrain power consumption to 40 volt and made this transmission more efficient. Electric actuators, as a part of the transmission control mechanisms, can operate with the non-running engine and when the car is not moving. The electronic transmission control unit (TCU) is mounted on the transmission case. By means of the wiring harness, the TCU is connected to 5 electric motors, 2 speed sensors, oil temperature sensors, sensor of engaged gear and two pressure sensors in clutch actuators. The TCU software was designed taking into account demands of 23 automakers using Getrag transmissions with 2 clutches. Usually, the transmission is equipped with the open-type differential, so the oil filling operation is performed when the transmission is installed on the car and when the wheel drives are mounted. However, at the request of the car manufacturer, the PowerShift 7DCT300 may be equipped the differential of the closed type. Currently, dual-clutch transmissions produced by Getrag are installed on such cars as Ford Focus, Ford Galaxy, Renault Clio RS, Honda-Acura, Ferrari 458 Speciale, BMW-M, Volvo, Qoros.

Transmission general data The Hydra-Matic range 6L45 - ... 6L90 is the second generation of modular-type 6-speed automatic transmissions, used for RWD vehicles. The 6L80 and 6L90 were the first automatic gearboxes of the Heavy-duty class designed in 2005. Next year 6L50 \6L45 gearboxes of the Medium-Duty class (with a lower torque) up to 450 Nm replaced BMW gearbox, which was popular in repair services. The 6L45E (GA6L45R) is a constructively modified 5L40 (which was actually replaced by the 6L45E in 2007 ). Mainly used with budgetary BMW-3 and X3 with engines 2.5l - 3.0L. 6L50, 6L80 and 6L90 transmissions may be considered as quite reliable RWD 6-speed gearboxes of GM series. European modifications 6L45 /R have been used since 2006 on BMW Х1, Х3 of 1-st 3-rd and 5-th series and manufactured in Strasbourg, France. These gearboxes mainly differ in electrical components. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATRWD4509,86,2Mercon SP These gearboxes usually get in repair services for scheduled ATF change, replacement of the filters with the pan gasket. ATF gets contaminated because of aggressive accelerations and wear-out of the lock-up clutch. It is recommended to change ATF in accordance with its contamination level, but no later than after travelling 80 thousand kilometers. Typical problems The problem detected on the 6L80 (manufactured before 2008) is related to the design of the pump cover and cranking of filler rings resulting in problems with shifting from the 2-nd to the 3-rd gear and delays in switch-on of Forward or Reverse gears. In case of the overhaul, it is recommended to check the leak integrity of the drum 555. There may be some hidden cracks leading to the operation pressure losses in packs causing problems when shifting gears 2-3 and Reverse. Overheating is dangerous for all pistons, which have to be fully replaced. It is the problem inherited from its 5-speed predecessor 5L40E. All pistons and retainers are replaced quite frequently (kit of pistons 6L45-50). Problems with the torque converter (TC) may also occur in these gearboxes. The wheel-hub early gets out of order. Rare and complicated cases of the overhaul show some vulnerability of the pack (4-5-6 Clutch), which in neglected cases leads to burning of all frictions, including steel discs and pistons. The reason is often related to wear-out of the TC bushing and TC itself. The torque converter is often considered to be a soft spot in American gearboxes. After 100-150 thousand kilometers (depending on engine and driving style), it is recommended to test the TC seal for leaks. When there are leakages in the seal or ATF gets rapidly contaminated, then it is desirable to get TC in repair services to prevent problems with the pump or the valve body. This measure particularly should be applied when automatic gearboxes operate jointly with motors (with maximum torques).

Transmission general data The 6DCT250 6-speed transmission has been developed for front-transverse installation in medium and compact cars with the torque capacity up to 280 Nm. This transmission is equipped with a dual wet clutch. Currently, this transmission is installed in almost all Ford models. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6DCTFWD1,81,875w90 A smooth gear shifting is ensured thanks to the parallel operation of two main shafts, actuated by the clutch system. In practice, it is implemented in the following way: one clutch selects the necessary gear, while the other one prepares the next gear for engagement. It is worth mentioning that the gear shifting process in the 6DCT250 transmission rules out the possibility of torque losses. In other words, the automatic transmission successfully combines all conveniences of automatic transmissions and the efficiency of manual transmissions. This transmission may have a separate PTU with AWD system, as well as a start-/stop feature without modification of the hardware. Combined with an E-motor, the gearbox may also be applied in a hybrid drive. Peculiarities of operation: In terms of design, this transmission is a nonstandard solution, which specifies special requirements for the maintenance and operation of the vehicle: - When stopping the car, the driver has to press the brake pedal, using the handbrake lever, and only then shit to “P” parking position; - When using the vehicle in the "Select-Shift" mode, the driver should not keep the button “+/-“ pressed; -When the engine runs idly, the driver should switch the selector into “P” (parking) or into “N” (neutral) mode; - When selecting “R” (reverse), “S” (sport), or “D” (drive) mode, it is not recommended to keep the brakes engaged for a long time; - Transmission repair specialists recommend changing of ATF and filter after each 45 thousand kilometers. It is important that this procedure should be performed at special services. Problems The most common faults in the 6DCT250 Powershift transmission are related to the clutch system. Due to structural stiffness, this transmission component responds to ECU malfunctions, which may lead to wedging and gear failure. In some cases specialists detect ATF leakages in the primary shaft seal. The ATF appearance on the clutch may lead to slippage.

Transmission general data The 4-speed automatic transmission 4L40E produced by GM found application on the most common BMW 318 (since 1998). This automatic transmission was designed on the constructive basis of a reliable 4L60E, but were produced in Europe for the Bavarian automobile factory. This range of automatic transmissions replaced the 4-speed 4L30E and had been in production until 2007, when GM replaced these transmissions with the 6-speed 6L45. In terms of design the 4L40E (5L40) is the most simple, robust and reasonably priced transmission. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATRWD36095,5-6Dexron VI Technical issues and repair guidelines The repair of this transmission mainly lies in the replacement of filter, gaskets and seals (preventing oil leakage), and replacement of burnt friction elements. All parts are interchangeable with 5L40E and 5L50E. Frictions are one-sided as in the popular DP0 transmission. The pack (Direct Clutch; 2nd Coast) burns twice as frequently as other clutch packs.Generally, this gearbox is considered to be reliable and almost “invincible”, when avoiding heavy ATF contamination by friction dust and the abradant which wears out not only friction nodes, but also the valve body. This issue (oil contamination) often results in self-regulating pump becoming “unregulated”, also remaining in the mode of ultimate capacity. It leads to the rapid gear-shifting as well as to increased pressure in packages resulting in pistons damage. Issues with pistons is a typical soft spot for the 5-speed 5L40E and 5L50E (BMW Х5). The rubber-covered piston (forward) most commonly gets out of order because of its design peculiarities.It is usually recommended to take care about the ATF quality for this transmission.

Transmission general data The 10R80 is a 10-speed automatic gearbox designed thanks to fruitful cooperation between Ford and GM (10L90). Both companies pointed out the fact that while the mechanical part of the gearbox was developed collaboratively, the software part of the 10R80 will be different for each manufacturer and, as a result, their corresponding powertrain structures should not necessarily resemble each other in view of gear shifting algorithms. This transmission has 10 forward gears, three of which are overdrive ratios. It's deep 4.69 to 1 first gear ratio is the lowest in its class and it features a relatively tall 0.63 to 1 final overdrive ratio. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type10ATRWD/4WD80012.98Motorcraft ULV A built-in electrohydraulic pump ensures that the "start-stop" feature operates with minimal delay. The 10R80 includes 3 operation modes - "Tow Haul", "Sport", and "Normal", with each mode changing the gear shifting algorithm and characteristics to compliment particular forms of driving behavior. Since the gearbox has 10 forward gears, its running characteristics and, more importantly, fuel efficiency is maximized by the transmission's capacity to get a suitable ratio for current operating conditions, such as engine speed, load, and car speed. This transmission became a standard option for the 2017 F-150 equipped with the 3.5L Eco-Boost engine.
