Um what did you want to know ?
Transmission: RealTime™ 4WD system
Honda's RealTime™ 4WD system - which automatically engages all-wheel drive only when required - now delivers better acceleration and hill climbing performance on slippery (particularly) snow covered) surfaces, as well as a swifter response when accelerating around corners or turning out of slippery intersections. The new system uses a one-way ball cam and pilot clutch to transmit torque instantaneously and responds to even the slightest amount of wheel spin. Thicker stabiliser bars also contribute to greater stability.
The RealTime™ 4WD system on the CR-V is designed to overcome the traditional drawbacks of a full-time four-wheel drive system - notably lower fuel economy, higher noise and vibration levels, higher weight. The CR-V's RealTime™ 4WD operates automatically and only when needed. It requires absolutely no intervention on behalf of the driver for it to be engaged or disengaged.
The CR-V's RealTime™ 4WD system sends power only to the rear wheels when there is insufficient traction for the front-wheel drive system. The system consists of the conventional front-wheel drive system - a compact transfer system that distributes drive to a propeller shaft running the length of the vehicle, a dual-pump system, the rear differential, and left and right rear wheel driveshafts.
The heart of the system is the dual-pump unit. It consists of two hydraulic pumps - one driven by the front wheels via the propeller shaft and one driven by the rear wheels via the rear differential.
A hydraulically actuated, multi-plate clutch - similar to the clutches used in Honda automatic transmissions - connects the propeller shaft to the rear differential.
When the CR-V is operating with the front and rear wheels turning at the same speed - for example, on dry bitumen - the front and rear hydraulic pumps operate at the same speed.
Hydraulic fluid circulates between the two pumps; however, no pressure is generated. In effect, the fluid fed by the front pump is absorbed by the rear pump.
If the front wheels begin to turn faster than the rear wheels - as would be the case if they were spinning on snow or ice - the two hydraulic pumps would turn at a different rate and hydraulic pressure proportional to the difference in their speeds of rotation would be generated. The resulting hydraulic pressure opens a valve body and feeds pressure to the multi-plate clutch, which engages the front propeller shaft to the rear differential. The rear differential feeds the drive torque to the right and left rear wheels.
System operation is completely automatic - no electronics or driver action is involved. The greater the degree of front-wheel slippage, the greater the amount of torque fed to the rear wheels. RealTime™ 4WD is also practically maintenance- free, requiring only a scheduled fluid change at 120,000 km and every 60,000 km thereafter.

bolt up or are you willing to go crazy?
cause you'll need the latter if you want it that badly just start with an wagon with it oem get an a6 mpfi and 6 speed tranny
