The warning light on the dash has been on for two weeks, which should have given you a clue that something was awry with your luxury SUV. Now your BMW X5 transmission needs repairs, so you have to find some replacement parts. The X5 is the second generation of the maker's mid-size crossover SUV. It had a relatively short production run from 2006 through 2013. There are no manual options for this vehicle; all models come with six-speed automatic transmission with Steptronic. The newer eight-speed 8HP automatic transmission, developed by ZF and BMW, is standard for the 2011 xDrive35i and xDrive50i models. The X5 4.4 transmission holds 9 liters of fluid, which never needs to be replaced according to the manufacturer; however, you if you want to revitalize the fluid, BMW recommends only changing around 45 percent and using the identical product already in the vehicle. If you need a BMW X5 transmission, replacement parts, or transmission fluid, browse the large inventory on eBay to find exactly what you need to get back on the road.Shop the extensive inventory of motors, parts, accessories, and complete auto transmissions for BMW!
