Tips for Keeping the 6HP26 Transmission in Your BMW X5 Running Strong

Posted by on Friday, September 5th, 2014

The 6HP26 is a six speed automatic transmission made for BMW by the ZF Friedrichshafen AG Company. It uses a special planetary gear set that can provide more gear ratios while making the transmission lighter than its predecessor — a five-speed transmission. This transmission is used mainly in high-end luxury vehicles, but it has recently found its way into some not so high-end luxury vehicles such as the Hyundai Genesis. Rated for use in motors that put out as much as 440 Ft Lbs of torque, it is a fairly heavy duty transmission. The 6HP26 comes with a very steep first gear ratio of 4.17:1, which is great for quick jack rabbit starts. It also comes with a 0.69:1 ratio overdrive gear, which helps the car it’s used in get better gas mileage as well.  First put into production in 2001, this transmission is still being produced today.  The 6HP26 can be found in a wide variety of vehicles, including the Jaguar XKR, the Jaguar XJ, the Ranger Rover, the Rolls Royce Phantom, the BMW 5 series, the BMW 3 series, the Maserati Quattroporte, the Kia Mohave, and finally, the BMW X5.
