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.

Technical issues and repair guidelines
These transmissions rarely get in repair services, because of reliable rear drive construction which operates properly for the first 4-5 years of service without serious problems.
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.
