ZF 6HP26 transmission

From Wikipedia, the free encyclopedia

The 6HP26 was the first 6-speed automatic transmission in a production passenger car. Released by ZF Friedrichshafen AG in 2000, it was manufactured by ZF Getriebe GmbH in Saarbrücken, Germany.

The 6HP26 uses a Lepelletier planetary gearset, which can provide more gear ratios with significantly fewer components. This means the 6HP26 is actually lighter than its 5-speed predecessors. It also has the capability to achieve torque converter lock-up on all six forward gears and disengage it completely when at a standstill, dramatically closing the fuel efficiency gap between automatic and manual transmissions.

The 6HP26 was first used BMW on the 2001 E65 7 Series, though Audi was the first announced user with their 2003 A8.

While the 6HP26 itself is rated for a maximum input torque of 600 Nm, sister products with different ratings exist in the form of the 6HP19 and 6HP32. In addition to this, several versions of the 6HP26 are available depending on application and brand: 6HP26, 6HP26A and 6HP26X.
