![]() Finally, demonstrating the attention to detail in engineering, the ball bearing contact areas have been reduced between rolling elements to help boost the powertrain’s efficiency. The groove patterns are engineered to optimize the clutch for low drag, while a refined baffle plate minimizes the churning losses of transmission oil. Castrol Transmax ATF 8-Speed, formulated with Smooth Drive Technology, is designed for most modern 8 speed. The new transmission also features a three-pronged approach to friction loss, ultimately boosting economy. The transmission’s damper control multi-disc torque converter is another key technology that enhances fuel economy and drivability.Ī separate system to control the 4-disc damper clutch, instead of a single disc, allows the enlargement of the lock-up range and faster response for damper control. This integral component may reduce the power of most auto transmissions, so the company improved efficiency of the 8-speed automatic transmission by optimizing the teeth and reducing the size of the pump gearing. Other optimized parts include a re-engineered oil pump. The window sticker and the Ram Vin Decoder says it has an 8Speed Automatic 8HP70 Transmission but all of the specs I see for 2019s on the Ram site has the info for a 8Speed Automatic 8HP75 Transmission. By simplifying the structure of the valve body, the new transmission reduces oil leakage and improves the stability of gear shifting. Hello All, Great site I bought a 20 CLASSIC SLT CREW CAB 4X4 LONE STAR Axle ratio 3.21 on Monday. Volkswagen Amarok TDi420 Highline 2H Turbo Diesel Auto 8 Speed Dual Cab. 2013 Jeep Grand Cherokee Laredo (4x4) WK Automatic - 8 Speed Wagon. The unit’s gains in economy and performance come from several sources including a direct control valve body that allows solenoid control of the clutch directly rather than via several valves. 2014 Jeep Grand Cherokee Laredo WK Auto - 8 Speed Wagon (WOVR-Inspected) 2019 Volvo XC40 T4 AWD INSCRIPTION Automatic - 8 Speed Wagon. Even with all these improvements, the weight has also been reduced by 3.5 kg from the 6-speed automatic transmission. By increasing the gear span with a more number of gears, the transmission comes with an improved acceleration performance at the low gear range, and enhanced fuel economy and NVH at the high gear range. The new transmission is based on a unique layout, with an additional clutch to Hyundai Motor’s 6-speed automatic transmission. I cant find any hard specs on the 850RE except gear ratios. This is not the same ZF 8 speed that has been around for a few years behind the Hemi and such. Coupled with better driveability and smoothness of the wider gear span, Hyundai Motor will present a powerful new option with its Lambda, Theta turbo GDI, and R-Engine family engines, targeting the large and luxury car segments. I believe the Wrangler gets a lighter duty version 8 speed auto, the 850RE. The new Hyundai 8 speed automatic transmission has improved fuel economy by an impressive 7.3% when compared with the existing 6-speed automatic transmission unit and will arrive to Hyundai & Kia FWD models suchs as new K7, Aslan and the future Grandeur. ![]()
