Taking a 1982 Rover SD1 3500 VDP Automatic out for a drive 

The auto was always a 3-speed on the SD1.

i love it , is it on sale , where ? price ?

GM 180 three speed after 1982 and Borg Warner 66 three speed pre 82

Is box a torque converter type

Yes, it's a very early MK2 which still has the Borg Warner box, later ones have a GM gearbox.

SD1Rover thought so with that whine in 1st. Yours sounds exactly the same as my 1992 Ford Fairlane with Windsor V8, as it took of in 1st gear. The gearbox in mine is a derivative of the 3 speed BW-35 but with 4 forward gears and electronic control, made by BTR Australia.

Great car you have! The SD1 is not mine, I was only filming :). The car belongs to a friend who's driving in the video. Meanwhile the car has got a lot TLC including a gearbox rebuild, much smoother now.
