What kind of gearbox does the E39 M5 have?
All E39 M5s are equipped with a Getrag Type D six-speed manual gerabox with the following ratios: 4.23 (1), 2.53 (2), 1.67 (3), 1.23 (4), 1.00 (5), 0.83 (6). Though this same gearbox (and ratios) was also offered in the E39 540i, the E39 M5 drivetrain has three unique components: The clutch is reinfoced to cope with the added torque of the S62 powerplant and the rear differential utilizes a shorter 3.15:1 ratio and features a limited slip device (25 percent maximum locking).
