Car transmission ?

[ken masoumi]

my opinion is the car should be at a dead stop before shifting from reverse to drive. This will put much less strain on the drivetrain components such as the constant velocity joints for front wheel drive, the engine and transmission mounts, and the transmission internal parts.

Absolutely right.
I would also add,a car would have less wear & tear in steering components,linkages,hydraulic pump.rack & pinion if in motion while steering rather than from a stock still/ motionless.

Rentals, now there's a car that can go from forward to reverse at any speed. Company vehicles come a close second .

I let my truck roll slowly when I put it in drive. Keeps the U-joints from getting torqued on take-off.
