ask your transmission guys to clear their part. Inform them of packet loss you've found.
especially if the transmission you are using in your network is microwave.

FIrst Xcheck with Ping Jumbo Pipe more than 1500 unfragmented
second xcheck MTU size all path
third xcheck BW setting from node--transmission--RNC
fourth xcheck autonegotiate between node & Transmission should same on both setting

If you don't mind,
Could you share more details how to do your recommended checks
