Hi all! I'm looking at replacing the gearbox on my 2011 Range Rover 4.4 TDV8 8 Speed. Its an Australian vehicle and the numbers on my existing box are BH4207000-AD (stickered on) and 1097 401 091 below it (stamped on which I assume are ZF numbers). I've found a replacement from the UK with BH4207000-AG and same stamped numbers.

Can anyone advise if the replacement box will suit from the numbers please? More specifically, does the difference in last 2 letter matter (i.e., AD vs AG).

Would appreciated any help/advise.

Thanks
Shane
