Hello guys am new to the group and would like a bit help I've recently purchased a range rover l322 and it's got a problem with the auto box nothing showing on dash you can drive it when it's freezing cold for about five mins then it stops selecting gears no crunching noises and the (D) for drive on the dash won't change either and it won't select anything (apparently has had gearbox service in the last 30.000miles so half ruled that out but not fully) also has a problem with the suspension too but that shows on the dash and says (air suspention inactive) and it won't do anything ive messed with the button and pump makes a noise but not for long I haven't had it plugged on to diagnostic yet but will tomorrow hopefully and will post codes if there is anything else to try let me no it would be a great help
