'My 21 HEMI runs great with a ZF8HP. I've driven 4, 5, 6, 8, and 10 speed transmissions. ZF8 is my favorite. If I could, I would tune mine for firmer shifts.

The ZF8 would be fun to drive with a 3.0i or V8 X5. The two OD gears are nice. The 4.11 gears would benefit from 1st-6th gears. The slush box goes through the five gears too fast. It runs in 5th at too low of a speed. If I need acceleration, I slap it to Sport Mode.
