Hi as some may know i had a new transfer box fitted yesterday under warranty on my 2012 fls hse sd4.Would they have had to mess with the gear box as i went for a ride today and sometimes its not changing gear at 2000 rpm it wouldn,t even go into 6th gear sometimes i was going down the m1 at 70mph on 3000rpm doing about 12mpg on inst mpg.Could they have messed something up or will it settle down after a while.I will be double checking it Sunday morning when its quiet and reporting back to the dealer if still the same.TIA
