Vr auto 4hd to 5hd

[Jesse018394]

Hey guys, new here. Not sure if it has been covered recently but haz anyone succesfully changed the auto from 4hd to later such as 5 or 7hhd? If so what is needed? Wiring inside box change, solenoid change?.
Any help would be greatly appreciated.
Cheers

I know 4 is a 12pin plug, where 5 onwards is 13pin.
Cannot confirm if a swap can be done or not.
