320cdi 2008 trouble

Hi guys! My little ML 320cdi started having a problem .. it doesnt seem to understand how to shift gears and just tries and fails around 2k rpm. I kick Down the gass and after a while it gets up in speed but takes a while and manages to shift gears. Doesnt help manually shifting gears - same happened. Like the car almost jumps trying to Get in to gear but cant. Some Said it might be an egr vaulve?

Check the transmission fluid level, but budget for a replacement gearbox and TC
