I'm pretty sure an 02 is a 47re. 48re's only came on third gens to my knowledge
They changed the RE harness in 00, easy fix is to swap the later VB back in... As for the RE swapping with an RH you would need the OD section out of the RH for the governor and feed tubes, plus the OD piston retainer for the ports to accept the governor feed tubes. There is a bushing available to bush the larger RE hole down to the RH plug.
